Presentation on the topic: "Insects are harmful and beneficial. The nose is long, the voice is thin. Whoever kills him will shed his blood

March madness - this is how those who grow seedlings of their favorite vegetables themselves perceive the first calendar month of spring. In March, they sow their favorite tomatoes and peppers, carry out the first crops in the greenhouse and even sow vegetables in the beds. Growing seedlings require not only timely diving, but also considerable care. But only her efforts are not limited. It is worth continuing to sow in greenhouses and on window sills, because fresh herbs from the beds will appear not so soon.

While the buds have not yet woken up on the plants, or at the very beginning of growth, seedlings and delenki adapt much better. Although the main attention in March is still riveted to completely different plants - seasonal ones. Growing your own seedlings allows you to save money, find new varieties and ensure plant health. Moon calendar in March, for ornamental crops, it recommends choosing days more carefully, because unfavorable periods cover almost half a month.

In the month of March, most of the flowering annuals are sown, which need seedling method cultivation. Usually, these flowers take no more than 80-90 days from germination to flowering. In this article, I would like to focus on interesting annuals, which are a little less popular than ageless petunias, marigolds or zinnias, but they have no less advantages. And they are also worth trying to plant for flowering next season.

With the approach of spring, indoor plants gradually come out of dormancy and start growing. Indeed, already in February, the day becomes noticeably longer, and the sun warms up in a completely spring-like way. How to help flowers wake up and prepare them for the growing season? What should be paid attention to and what measures should be taken so that the plants are healthy, bloom, multiply and please? We will talk about what houseplants expect from us in the spring in this article.

Coconut buttercream cake with whipped cream is a real treat. I made this cake based on the traditional German coconut pie - kuchen. Coconut cake "Kuhyun" is easy and quick to bake. The cake is soaked in heavy cream, so the cake based on it turns out to be moist and very tasty. In this dessert, coconut is everywhere - in the biscuit, in the cream, even in the whipped cream, I added a few drops of coconut extract. All in all, it was a heavenly delight!

One of essential rules growing strong and healthy seedling- the presence of the "correct" soil mixture. Usually, gardeners use two options for growing seedlings: either purchased soil mixture, or made independently from several components. In both cases, the fertility of the soil for seedlings, to put it mildly, is doubtful. This means that the seedlings will require additional nutrition from you. In this article we will talk about simple and effective top dressing for seedlings.

After a decade of dominance in the catalogs of the original variegated and bright varieties of tulips, trends began to change. At exhibitions, the world's best designers offer to recall the classics and pay homage to the charming white tulips. Glittering underneath warm rays spring sun, they look especially festive in the garden. Meeting spring after a long wait, tulips seem to remind you that white is not only the color of snow, but also the joyful celebration of flowering.

Sweet Indian pumpkin chutney with lemon and orange originated in India, but the British contributed to its popularity around the world. This sweet and sour spicy seasoning of vegetables and fruits can be eaten right away or prepared for future use. For harvesting for the future, use fruit or wine 5% vinegar. If you keep chutney for 1-2 months, then its taste will become softer and more balanced. You will need butternut squash, ginger, sweet orange, juicy lemon and spices.

Despite the fact that cabbage is one of the most popular vegetables, not all summer residents, especially beginners, can grow its seedlings. In the conditions of the apartment they are hot and dark. Quality seedlings in this case, it is impossible to obtain. And without strong, healthy seedlings, it's hard to count on good harvest. Gardeners with experience know that it is better to sow cabbage for seedlings in greenhouses or greenhouses. And some even grow cabbage by direct sowing of seeds in the ground.

Flower growers tirelessly discover new indoor plants for themselves, replacing one with another. And here the conditions of a particular room are of no small importance, because the requirements for their content in plants are different. Difficulties are often faced by lovers of beautiful flowering plants. Indeed, in order for flowering to be long and plentiful, such specimens require special care. There are not very many unpretentious plants blooming in rooms, and one of these is streptocarpus.

Chicken rolls "Cordon Bleu" with bechamel sauce - an excellent dish for holiday table and daily meals! It is prepared simply and quickly, it turns out juicy, and also a thick bechamel sauce - you will lick your fingers! With mashed potatoes, pickled cucumber and a slice fresh bread you will have a hearty and delicious dinner. Cheese for this recipe, choose according to your taste, it can be processed, it can be with blue mold. It is important that the cheese and ham are cut very thinly, this is the secret of success!

Calendula (marigold) is a flower that stands out among others with its bright color. Low bushes with delicate orange inflorescences can be found on the side of the road, in the meadow, in the front garden next to the house, or even in vegetable beds. Calendula is so widespread in our area that it seems that it has always grown here. About interesting ornamental varieties calendula, as well as the use of calendula in cooking and medicine, read our article.

An elegant and sophisticated orchid is a unique plant, it cannot be classified as an ordinary flowering crop. Growth form, requirements for growing conditions, type of rhizome - this plant is all different from other types of representatives of the flora! Some orchids grow in room conditions, hardy and not very whimsical, others - capricious plants in need of special showcases, greenhouses. Exquisite flowers and care require special, competent feeding and watering.

I think many will agree that the wind is well perceived by us only in a romantic aspect: we are sitting in a cozy warm house, and the wind is raging outside the window ... In fact, the wind walking through our sites is a problem and there is nothing good in it. By creating windbreaks with plants, we break strong wind into several weak streams and significantly weaken its destructive power. How to protect the site from the wind will be discussed in this article.

Irina Leonidovna Ermolaeva, a specialist in plant protection against pests and diseases, tells.

In our gardens there are not only visible enemies, but also friends. These are various predatory beetles, ground beetles, hoverflies, ladybugs, ants and spiders, which, while eating, invisibly help us, destroying pests at different stages of development.

To attract beneficial insects and to stimulate their active work, nectarifers should be sown, i.e. plants that attract such helpers. These are phacelia, mustard, buckwheat, carrot seeds, onions, etc. Moreover, it is necessary to create a flower-nectar conveyor - sow them in different dates between rows or empty spaces.

fly tahina

One of the many beneficial insects is the tahina fly. The range of pests that it destroys is simply huge, and its effectiveness is high. Suffice it to say that the number of silkworms, sawflies, leafworms, moths, tahini moths is kept under constant control. The survival and accumulation of these flies is facilitated by the presence of flowering carrots, parsnips, goutweed and other umbrella crops.

The body of tachin flies is usually covered with strong bristles, and therefore they are also called sand flies. The family of flies-tachin has about 5 thousand species.

Tahini flies find their hosts in different ways. Some types of flies lay their very small eggs on the surface of the leaf where the caterpillar feeds. Caterpillars, eating the leaf, swallow the eggs, then larvae appear inside the caterpillar, which feed on the body of the host insect, which leads to its death. Other species lay their eggs directly into the body of the insect host. And, finally, there are types of tahini, the larvae of which themselves find the owner and bite into his body.

Tahini flies lay a large number of eggs, and therefore one fly can kill many caterpillars.

Ants and spiders

Ants and spiders do a great job of destroying pests. Coriander and anise can be sown next to cabbage. When sown at the same time, they bloom from May to September. Their flowers feed many beneficial insects and do not attract butterflies whose caterpillars damage cabbages.

Ants are nurses. They build their houses in the soil and above it and are of great benefit. Numerous passages of ants make the soil looser, and this improves the breathing conditions for plant roots. Getting their own food, ants bring a huge number of insect pests and their larvae into the passages and chambers of the anthill: the inhabitants of only one anthill destroy an average of up to 20 million garden pests per year. But it is worth watching for an increase in the number of ants, this can lead to oppression of the garden, and because of the favorite delicacy of ants that aphids secrete, they also contribute to the settlement of aphid colonies. Here you need to think about whether to leave the ants in their areas or not.

Spiders. A significant part of the prey of spiders of the families of jumping spiders (Salticidae), funnel spiders (Agelenidae), wolf spiders (Licosidae), sidewalk spiders (Thomisidae) are such dangerous pests, like a harmful turtle, Colorado potato beetle, meadow moth, different kinds moths, many Diptera.

Attention! I want to warn you that beneficial insects, like pests, overwinter in the bark, leaves, in the soil on garden plot. And in the summer, you should not catch all the insects you see in the garden, because you can leave the garden without defenders - beneficial insects, which are called entomophages.

ladybugs

Everyone knows what a ladybug looks like, but not everyone knows what benefits it brings. She is fertile and lays eggs in small groups of 30, the eggs are yellow, similar to eggs. colorado potato beetle and hawthorn butterflies.

An adult beetle eats 100-200 aphids per day, the larvae are ten times more voracious than mites, whiteflies (Aleyrodidae) and mealybugs (Coccoidea).

Ladybugs will be attracted to our garden by plants of the Compositae family: daisies, tansy, or yarrow.

Ladybug Larva

ground beetles

These workers can be seen in the process of digging or loosening the soil. These are nocturnal predators that prey on insects living in the soil: moth pupae, moths, larvae of click beetles (wireworms), gall midges. Destroy slugs and caterpillars. The menu of one ground beetle per day is about one hundred moth larvae, 5 adult moth caterpillars and 5-6 weevil larvae. And the larvae are much more voracious than adults, they sit in dug holes and grab insects crawling past.

To have more ground beetles in the garden, take care of soil fertility. Those. apply in spring and autumn organic fertilizers, humus, etc.

lacewing

This is a gentle and slender insect. The color is pale green. Adult insects feed on the nectar of flowers, aphids, pollen, as well as the mites and aphids themselves, destroying up to 4000 individuals per day. The larvae suck out spider mites and aphids. The lacewing prefers cool shady places covered with thickets of ferns for breeding.

flies-ktyrs

A two-centimeter ktyr cannot be confused with any other fly. Powerful paws armed with bristles and suckers. A strong proboscis, pointed at the end, protrudes from the flattened head. They ktyr can pierce even such a strong shell as beetles have.

Ktyri, destroying the mass harmful insects, are undeniably beneficial. Their menu includes beetles, flies, fillies, leafhoppers, butterflies and even caterpillars. Not only adult insects are useful, but also larvae that live in the soil and destroy the larvae of click beetles, beetles and dark beetles, locust eggs and caterpillars that gnaw on the scoop.

Interesting. The largest ktyri reach 5 centimeters. You should not touch the ktyri with your hands - their bite is as painful as a prick of a bee sting.

Such flies are attracted to plants from the aster family - goldenrod, chamomile, daisies, as well as various types of mint - catnip, peppermint and spearmint.

Trichogramma

This is an egg-eater, the mass reproduction of which has already been put on an industrial basis. Trichogramma females lay their eggs in the eggs of many pests - apple codling moth, yellow and pale-footed gooseberry sawfly, meadow moth, cabbage scoop, cabbage whites and others.

Since these insects are very small, they take nectar from small open flowers such as anise, dill. A good shelter for them are plants of the celery family.

From the above, it follows that the more nursery plants in the garden, the less pest problems you will have. These plants can be placed along the edges of the garden or border areas with vegetables. It is necessary to select plant species in such a way that they bloom for a long time, replacing each other. Marigolds, alyssum, tansy, chamomile, daisies are suitable for this. Savory, lavender, hyssop, basil, rosemary, oregano bloom for a long time.

You can name many more useful insects - our helpers. But their number is still less than pests. Birds, frogs and toads, dragonflies, spiders - many animals help to keep the garden and vegetable garden clean from pests and healthy. But they themselves are not protected from chemicals.

Chemical treatments primarily destroy beneficial insects, since for a number of reasons they are more sensitive to chemistry and, in addition, their numbers are much smaller. Against the background of an abundant food base and the absence of natural enemies, the pests remaining after processing begin to multiply intensively. First of all, this applies to sucking pests - aphids and mites, which give several generations during the growing season.

This information is for lovers of chemistry and for those who consider it necessary to destroy everything that flies, crawls, jumps around the site.

With this good mood, we will begin our lesson. And we'll go to the forest clearing.

Speech gymnastics.

(slide number 3)

I propose to start our lesson with speech gymnastics.

(in chorus)

Came to us yesterday

Striped bee.

And behind her - a spider

And a cheerful moth

Two beetles and a dragonfly

Like flashlight eyes.

They circled, they flew ....

Were tired...

4. Communication of the topic and purpose of the lesson.

Look at the picture and find those representatives of the animal world that you met in the poem?

(bee, spider, moth, dragonfly, ladybug, weevil)

How can you call them in one word?

These are insects.

Do you think the world around us can do without insects?

(children's answers)

Do they benefit or harm the environment?

(children's answers)

(slide number 4)

What do you think the topic of our lesson will be?

Topic: Insects harmful and beneficial.

Then let's try to formulate the purpose of our lesson.

The purpose of the lesson: to learn new things about insects, to be able to distinguish between harmful and beneficial insects.

We already know that there are a lot of insects in the world. They are quite small and large. Some fly, others crawl or jump. Some live for several years, others - one day. Some are beneficial, others are harmful.

Today we will review what we know about insects, as well as find out what two groups insects can be divided into, we will learn to work in pairs, discuss various tasks and evaluate ourselves.

(slide number 5)

- On the desks you have self-assessment sheets, in which we will evaluate ourselves as we complete the tasks. If everything is clear to you, you will make a mark with a green circle, if you didn’t understand everything, there were difficulties - a yellow circle, if you didn’t understand anything - red.

Grade

Everything is clear, no errors (5 points)

Understandable, but not all, difficulties arose (1-2 errors) (4 points)

Didn't understand anything (3-4 mistakes) (3 points)

5. Learning new material.

a) familiarity with the appearance of insects

Guys, we already remembered a few insects. What other insects do you know?

(children's answers)

Correctly. You named a lot of insects. How do you distinguish them from other representatives of the fauna?

By appearance.

Quite right. It is possible to distinguish insects from other representatives of the fauna in appearance.

Purpose: I suggest that you look carefully at the presented insects, and try to identify their body parts.

(slide number 6)

(children's answers)

Insects have: body (chest and abdomen), head, antennae, wings (not all), andsix legs .

(slide number 7)

Insects are the most large group animals. There is a whole science that studies insects, it is called"entomology".

Do you know why these animals were called "insects"?

(children's answers)

Word "nase coma" is translated from Latin as "havingnase chki”, “one who has incisions”. If you look closely at insects, you will see that their torso is, as it were, divided into three parts (head, chest, abdomen), the abdomen and legs have notches, and even on the wings there is venation.

So what have we learned about appearance insects? And why were they named that?

Conclusion: We learned that insects have: eyes, antennae, head, six legs, wings (not all), torso (chest and abdomen).Insects are so named because their body has notches.

(slide number 8)

b) The game "Test yourself"

(work in pairs)

I propose to check how well you remember the body parts of insects. You will work in pairs. On the desks you have cards number 1. You will need to connect the parts of the body of the insect with the name of this part with arrows.

(do work)

We check.

(children's answers)

We evaluate. In the task 1 column, we set points.

(evaluate)

(slide number 9)

Fizminutka

Chok-chok, heel! (Stomp your feet)

A cricket is spinning in the dance. (Spin around)

And the grasshopper performs a waltz on the violin without error. (Hand movements, as when playing the violin)

Butterfly wings flicker (Movement of hands, like wings)

She flutters with an ant. (Spin around)

Under a cheerful hopachok, a spider famously dances. (Dance moves)

Clap your hands loudly! (Clap your hands)

Everything! Our legs are tired! (quietly sit down)

b) harmful and beneficial insects

(work in pairs)

Do you think insects are good or bad? Why?

(children's answers)

Now, I propose to find out:Insects are harmful or beneficial.

You will work in pairs. Each pair has a card describing the life of an insect. Read and determine the harm or benefit brings given insect where it should be placed in our table.

Harmful insects

Beneficial insects

Colorado beetle

I am a foreign guest. Came to you from distant America, Colorado. I love to eat the grass of young potatoes, tomatoes, eggplants and other plants. Although my coloration is bright, orange-black, the birds do not touch me. My only feathered enemy is the pheasant. But he doesn't live everywhere.

Ant

I am an ant. We are called forest nurses. We destroy harmful insects that harm the forest. Ants in one nest destroy 15,000 insects a day. To get such a number of insects, the woodpecker has to work 20 days. Don't destroy the anthill! We are friends of people!

Aphid

I am aphid, very small insect but all the plants are afraid of me. I exhaust them, sucking out the juices, and pollute the leaves with their secretions, as if the soul of the plant. The leaves curl up and dry out.

Bee

I am a bee giving honey. Natural honey and bee venom have valuable healing properties. I also pollinate plants. But many animals, birds and animals die from my bites. Here the hedgehog does not react at all to my bite.

Ladybug

I am a ladybug, only at first glance I seem like a harmless bug, but in fact I am a terrible predator. I quickly run through the twigs and leaves in search of food. My food is aphids, mites, Colorado potato beetle larvae and other pests. My appetite is good - I can eat 200 aphids a day.

(children determine the place of insects in the table and justify their answer)

Mosquito (read by teacher)

I am a mosquito. Who among you has not cursed our annoying mosquito tribe? Especially in nature, where the attacks of winged bloodsuckers are quite capable of ruining all the charm of a quiet summer evening. And sometimes there is no life from us in the city. But the masses of mosquito larvae living in the water of ponds and lakes serve there as one of the main sources of food for fish, especially young fish.

Guys, help me determine the place of the mosquito in our table. What kind of insect is it, harmful or beneficial?

(children's guesses)

Most often, we evaluate the harmfulness or usefulness of an insect from a human point of view, but sometimes insects harm humans, but benefit nature.

Is it possible to say unambiguously about all insects whether they bring benefit or harm? Why?

(children's answers)

So is the mosquito, for humans it is a harmful annoying, stinging insect, which leaves irritation on the skin, the mosquito is a carrier of infection, and for nature it is a beneficial insect whose larvae feed on fish. Therefore, I propose to make the third column in our table and put the mosquito there.

What do you think, was it right to destroy all harmful insects? Why?

(children's answers)

Conclusion: There are insects that bring only benefits; There are insects that bring only harm, and there are insects that can bring both benefit and harm.

(evaluate)

c) The game "Stomp - clap"

I offer youcheck how well you understand what benefits and what harm insects can bring.

If I talk about benefits, you clap your hands, if about harm, then stomp your feet:

Collect honey; (clap hands)

They eat harmful insects; (clap hands)

They are food for other representatives of the animal world; (clap their hands)

Carry infectious diseases; (stomp feet)

Bring joy and good mood; (clap hands)

They eat young greens; (stomp feet)

They give raw materials for medicines; (clap their hands)

Pollinate plants; (clap hands)

They eat the remains of dead animals. (clap hands)

Well done!You have learned well what benefits and harms insects bring.

(evaluate)

6. Consolidation of the studied material.

(slide number 10)

a) classification of harmful and beneficial insects

And now I invite you to work on your own and test your knowledge. On the cards you have representatives of the animal world. I will give you riddles, and your task is to find the insect in question and, if it is useful, circle it in green, and if harmful - red.

Raise your hand, who got a score of "5", "4", "3".

Well done!

And now I would very much like to know how well you felt at the lesson, whether you remembered everything. I suggest you populate daisies with insects. You have green, yellow and red butterflies on your desk. If you liked the lesson today, you understood everything and can teach this to your friend, you fasten - a green butterfly, if you were interested, but you didn’t quite remember something, you fasten - a yellow butterfly. And if you were bored, you didn’t remember well what we talked about, you fasten it - a red butterfly.

Well done! Look what a beautiful clearing we got.

Close your eyes. Mentally transport yourself from the beautiful clearing to the classroom. Open your eyes.

One of biological methods natural plant protection in the garden involves the use of beneficial insects as natural enemies harmful organisms, their study and assistance in settling in the garden and life in it.

Beneficial insects

Ladybug

The ladybug is a well-known beneficial insect in the garden. It belongs to round beetles and, depending on the species, is 4-9 mm long. The most common is the seven-spot ladybird. The beetle got its name for 7 black dots on the red elytra. But there are also beetles with yellow elytra and black dots, or dark beetles with light spots or without them at all. Also, the number of spots or the pattern of the wings can be varied. In total, we have about 70 species of large ladybugs, among which about 50 species feed on leaf aphids, and the rest on shell aphids and spider mites. Ladybugs, along with other leaf aphid killers, are the most important helpers in the garden.



Adult ladybugs hibernate on open field, for example, under foliage or dry grass. In spring, ladybugs lay 10-20 eggs vertically in a group on branches or on the inside of a leaf close to aphid colonies. The larvae from the eggs go through 4 stages. They are usually painted in dark gray with a yellow or red pattern. At the end of the larval stage, ladybugs begin to pupate and, as a rule, acquire a yellow color. After leaving the pupa, the beetle needs another 2-3 days before it acquires the final color. It is of particular importance that both the larvae and the beetles themselves belong to the species predatory insects, feed on aphids.


The seven-spot ladybug known to us destroys up to 150 aphids per day, smaller species - up to 60. While still being larvae, insects devour a total of up to 800 aphids. So, the female beetle destroys about 4 thousand adult aphids in her life.

When using a ladybug as a plant protection, its development cycles should be taken into account.

Stetorus, or tick ladybird

Active exterminator of spider mites. This is a very small, mobile, like mercury, beetle with shiny black elytra, a rounded body shape and a very small size for a beetle - 1-1.5 mm. The larva is small, gray, very mobile. Both beetles and larvae actively feed on mites and their eggs, destroying from 800 to 2000 pest individuals in their lifetime.

You can find beetles in places of accumulation of spider mites, most often on raspberries, on reverse side leaves. There were cases when even under production conditions, with a strong infection of raspberries with a spider mite, a predator completely exterminated the pest in a few days, and the need for chemical treatment fell away. In the garden, the conditions for stetorus are more favorable, and if, when a spider mite is found, you notice tiny black bugs on the back of the leaves, you should not worry: it will do its job - it will clean the plants from the spider mite quickly and efficiently.

By the way, and ladybugs, and stetorus can be collected somewhere else and released in your garden, they take root perfectly.

Osmia

These are fluffy solitary bees - and completely harmless. Here is a huge benefit to the garden. They fly out to collect nectar at air temperatures at which an ordinary domestic bee does not even show its nose from the hive. If you do not have buildings with a thatched roof on the site, we recommend making houses for osmium. Not only marsh plants, but also banal pieces of wood with drilled holes are suitable as houses. You can also use elderberry branches, inside they have a soft core that must be removed, and a hollow tube will remain - a house for osmium.

Osmia settle in the most unexpected places - in the hole from under the old nail, in the crevices. If a house is installed, osmia will take root, and you will be with apples, the garden will be pollinated perfectly.

bees

Bees are the true friends of the garden, as they bring him great benefits. They are the only reliable helpers of agronomists and gardeners. It is known that the vast majority of varieties of apple, pear, plum, cherry, raspberry, gooseberry are self-fertile, that is, their ovaries cannot be fertilized by their own pollen.
Thus, bees in the garden bring great benefits to humans in that, while collecting pollen from flowers, they simultaneously cross-pollinate plants.

bumblebees

Bumblebees are one of the most cold-resistant insects, well adapted to life in the harsh conditions of the north, where other pollinators either cannot live or fly for a short time.

Thanks to their long proboscis, they can extract nectar even from flowers with narrow corollas, thereby collecting pollen from plants inaccessible to other insects.

Bumblebees collect not only nectar, but also pollen from plants. Bumblebees help bring this delicacy to the nest special devices which are located on the hind legs. But pollen gets not only into special recesses on the paws. Sometimes dust particles linger on the abdomen, and then transferred to another flower.

Bumblebees can collect pollen and nectar from plants very, very quickly. Biologists have calculated that only one field bumblebee visits 2634 flowers during a flight lasting 100 minutes. Therefore, bumblebees are considered to be the best pollinators of this valuable fodder plant.

Gallica

Various species of the family of gall midges are better known to amateur gardeners as harmful insects (the larvae of a number of species develop in plant tissues, causing the formation of galls) than help in pest control. The body length of gall midges varies from 1 to 5 mm. Known pests in the garden include, for example, pear gall midge.

Useful gall midges feed at the stage of aphid larvae. The most important view is Aphidoletes aphidimyza. The female (about 2-3 mm in size) lays 50-60 eggs in one life span of 1 week not far from the aphid colony. Orange-red larvae hatch on the 4-7th day. The latter bite the aphids by the legs and inject a paralyzing fluid. The bitten aphid dies and is used by the larva for food. After 2 weeks, a fully formed larva falls to the ground and turns into a cocoon on the ground. After 3 weeks, a second brood hatches, whose cocooned larvae overwinter on the ground and hatch in the spring as adults.

Ground beetle

With early spring and until late autumn, quickly escaping beetles are found in gardens - these are predatory ground beetles that destroy eggs, larvae (caterpillars), pupae and adults of many harmful insects. One ground beetle per day can destroy three to five caterpillars gooseberry moth, up to ten caterpillars of the sawfly, up to one hundred larvae of gall midges.

They hunt at night, so they are rarely seen during the day. Beetles overwinter in the soil.

ground beetle larvae

Ground beetle larvae feed on the eggs of vegetable flies, small insects and their larvae, worms, slugs. These beetles are rarely seen in the garden during the day, they hide in shelters. The length of the ground beetle is up to 4 cm, it is very mobile. Many species cannot fly and therefore are active at night. The color of the ground beetle is the most varied: large black and completely yellow shimmering species are known. Adult insects hibernate in the garden in secluded protected corners, for example, under the house or woodpile.

Large ground beetles lay 40-60 eggs separately in shallow holes in the ground. The eggs hatch into larvae after a few days and hatch, depending on the species, 2-3 years before the pupa. After a pupal period lasting approximately 2-3 weeks, adult (developed) ground beetles hatch from them. Along with ground beetles, which live mainly on the ground, there are also arboreal and flying species. They feed on small insects and worms and therefore live in decaying organic matter, such as compost.

The ground beetles should be provided with shelter (foliage, sawdust and shavings, small heaps of stones), they live on open ground, sometimes hiding in earthen cracks.

Pesticides are the most terrible enemy of ground beetles!

Hoverflies

Hoverflies have great importance in horticulture, as their larvae feed on aphids. The larvae develop in different conditions– in soil, slurry or on plants. Visually, the hoverfly looks like a wasp, the length of an adult is 8-15 mm. The peculiarity of hoverflies, reflected in their name, is that in flight they can, as it were, hover in place, while making a sound that vaguely resembles the murmur of water.

Egg laying occurs in aphid colonies. Eggs 1 mm oblong white color. The larvae hatched from the eggs do not have legs and move like snails. They are white or yellow in color and look like fly larvae.

To hunt for aphids, hoverflies use their hook-shaped jaws, with which they firmly hold prey, sucking it out. The development of the larva to the pupal stage lasts 2 weeks. During this time, the larva eats up to 700 aphids. Hoverfly larvae are active mainly at night and do not go hunting until dusk. The hoverfly survives the pupal stage in a shell in the form of a droplet, located near the aphid colony on leaves or on the ground. Separate types several generations are bred, most - up to 5 per year. In some species, females hibernate in the same way as larvae or pupae. The hoverflies themselves feed on flower and honeydew, as well as aphid secretions.

Areas with flowering plants are most suitable for hoverflies, but not well-groomed lawns. Plants that bloom are especially fond of hoverflies. yellow flowers.

For overwintering hoverflies, you can leave small wooden boxes filled with dry grass or shavings.

Spiders

Everyone knows these insects with a rounded abdomen and a fused cephalothorax. However, not everyone knows about their role in nature. Most of them are predators. There are spiders in the soil, under fallen leaves, on herbaceous plants and trees. Often the web woven by spiders is confused with the web left by the common spider mite.

Trichogramma

Trichogramma females, 2-3 hours after birth and mating, begin to search for butterfly eggs, and when they find them, they pierce them with their ovipositor and lay their eggs in them. Depending on the size of the host egg, from 1 to 60 egg-eaters can develop in it. The duration of development depends, first of all, on temperature conditions and lasts from 8 days at 30ºС, 11 - at 25ºС, up to 53 days at 11ºС. The life span of an adult entomophage depends on temperature, humidity and carbohydrate nutrition (2-5 days without food, up to 7-15 days with feeding).

Goldeneye and its larvae

The lacewing, along with ladybugs, is an enemy of aphids. In our gardens, the most common species is green with yellow eyes. The beetle got its name precisely for these eyes. An adult has a wingspan of up to 3 cm. Green oblong insects wear house-shaped, transparent veined wings, folding them on the lower part of a long body.

The female lays about 20 greenish eggs individually or in groups on the bark or leaves. The larvae hatched from eggs develop depending on weather conditions within 2-3 weeks. Their length is only 7 mm, the jaws are long, sickle-shaped and pointed. The larvae feed on small insects, especially aphids. Individual individuals are capable of destroying up to 500 aphids during development.

After 18 days, the larvae hide in a protected place, wrap themselves around and turn into a white round cocoon. After the lacewing emerges from the cocoon, the next generation begins. In total, 2 generations can appear in a year. Adults feed, as a rule, on honeydew and pollen, on occasion they do not disdain small insects. The adult lacewing hibernates in secluded corners, so sometimes it can be found in residential areas. During the wintering period, the insect may acquire a yellow or brown color, but in the spring it turns green again.

aphids lion

Along with the common lacewing, we also have about 42 species of aphid lions, which, like the lacewing, belong to true lacewings. One of the most known species has a wingspan (brown of a specific shape) of about 3 cm. Adults and larvae feed on aphids and contribute to the biological balance in the fight against this pest.

Use for targeted biological protection plants in greenhouses and protected ground was tested and gave good results. For this, it is necessary for each square meter surface, place 20 lacewing eggs, which can be purchased at special biological laboratories.

Riders

The rider likes to settle in umbrella plants(dill, coriander, cumin, kupyr, etc.).

earwig

The common earwig, belonging to the leather-winged order, is well known to gardeners and gardeners. The length of the body is 3.5-5 mm, the front wings are solid, the hind wings are membranous. There are also wingless forms. Its claws located in the back of the body are impressive. The earwig hunts mainly at dusk and at night, and during the day it hides in dark narrow crevices.

By exterminating harmful insects, such as dahlia woodlice, earwigs can damage delicate young dahlia plants.

In spring and autumn, the female lays up to 100 eggs in a mink, which she pulls out herself, protects them and takes care of her offspring - first the eggs, and later the larvae. Earwigs overwinter in shelters - in the bark of trees, cracks in buildings, in the soil, flower pots filled with small chips or some other material, such as moss.

Can be used as shelter flower pots filled with wood shavings, moss or hay. These pots are placed between vegetable crops or hung on trees.

For the winter, the pots should be cleaned out, and refilled in the spring.

digging in trunk circles trees contributes to the normal functioning of the insect. Often, earwigs also seek shelter for the winter precisely under the trees, in its fallen leaves.

bedbugs

The predatory bug belongs to the class of weevils. Its various species have specific food sources. For some, it is the juice of a plant, for others, insects. For a gardener, the latter are of interest, first of all, which, among other things, destroy aphids. These include soft-bodied and false bugs, among which some species feed mainly on spider mites.

Flower bugs are small predatory insects 3-4 mm long. For 1 time, the female lays up to 8 eggs, mainly along the edges of the leaves. For a year, bugs breed 2 generations, and in areas with a warm climate even 3. Predatory bugs overwinter as adults. More large species flower bugs also feed on gall midge larvae.

How to attract insects to the garden?

If we take a lot of useful insects from somewhere and release them into the garden, then the effect will be only short-term. It is much more important that beneficial insects take root in the garden. To do this, you need to create for them suitable conditions. First of all, it is a food base and places for shelter and reproduction of beneficial insects.




For reproduction and increase in the species composition of beneficial insects, including predatory (entomophages), it is important to take into account their features:

Predatory insects are attracted to flowering plants, not pests (phytophages);
- Predatory insects use for reproduction and destroy the type of "host", i.e., the pest on which they themselves developed.

So, beneficial insects are attracted to the garden by flowering plants (flowering weeds), not pests.

The presence in the garden and on the lawns, in the fields of natural nectar-bearing flowers, even in small quantities, allows predatory insects to carry out additional nutrition in the breeding stages. Moreover, some predatory insects are able to reproduce effectively only by combining feeding on nectar or honeydew and insect prey. Therefore, the presence of flowering weeds, even in the fields where crops are grown, at a level below the economic threshold of harmfulness, increases the effectiveness of predatory insects and is considered appropriate.

There must always be a certain number of different pests in the garden in order for beneficial insects to survive.




Specialized predatory insects look for their "owner", i.e., the pest, no matter how numerous it is. Therefore, once again, there should always be a certain number of different pests in the garden, no matter how paradoxical it sounds! Usually, plants are planted in a hedge around the garden, on which pests develop and predatory insects survive. Only in this case can they prevent pest outbreaks. Polyphagous predatory insects show interest in one or another type of pest only when its abundance is high, so they are usually late.

Therefore, a variety of predatory insect species is necessary for sustainable pest control. And to expand the species composition and reproduction of predatory insects, their fodder nectar-bearing plants should be sown. These are usually compound umbelliferous and paniculate plants whose many small flowers provide many sources of nectar and together form a place where beneficial insects, including bees, and butterflies can sit.

Plants that attract beneficial insects

Tansy

The advantage of tansy is that the infusion of tansy leaves repels the Colorado potato beetle. I’ll add from myself, abundant herbage of tansy is good to use in composts. In such compost, the larvae of the bear and the May beetle do not start.

Decoctions from the leaves and flowers of tansy contain many different vitamins, essential substances, improve the taste of kvass, dough, and jam is made from flowers.

Chamomile

Perennial attractive to wasps and flies. During the flowering period, it is covered with many yellow flowers.

Lemon marigolds

Attracts small wasps and spiders. Seedlings are planted in the ground at a time when the danger of frost has passed.

Caraway

Attracts cunning bugs, spiders, small wasps, hoverflies and lacewings during the flowering period. Its fragrant seeds are used in bread baking and for making marinades.

Dill fragrant

Attracts ladybugs, hoverflies, small wasps and spiders.

Buckwheat

It is an effective soil-forming plant that increases the content of organic matter when plowed.

honey plant

It attracts not only pollinating bees, but also flies, ladybugs, hoverflies, predatory bugs.

Spearmint

It is used to make refreshing tea and as a fragrance. Mint is attractive to flies and spiders.




Many types of legumes have the ability to attract beneficial insects, for example: crimson clover, creeping clover, vetch. They provide beneficial insects with constant food and moisture, enrich the soil with nitrogen.

In order to ensure the presence of flowering plants that are attractive to beneficial insects for the whole season, you need to start with those that bloom earlier, for example, with buckwheat, which will be replaced by fragrant dill. Immediately you need to plant marigolds, calendula, so that they bloom in the middle of summer. You should grow tansy, sweet clover and navel, which bloom for a long time from year to year.

The task of using beneficial insects is not to completely destroy pests, but to control their numbers.

By creating conditions that would combine a favorable environment for beneficial insects and decorativeness, a natural balance can be achieved between the number of harmful and beneficial insects.

Ladybug is a well known beneficial insect in the garden. It belongs to round beetles and, depending on the species, is 4-9 cm long. The most common is the seven-spot ladybird. The beetle got its name for 7 black dots on the red elytra. But there are also beetles with yellow elytra and black dots, or dark beetles with light spots or without them at all. Also, the number of spots or the pattern of the wings can be varied. In total, we have about 70 species of large ladybirds, among which about 50 species feed on leafy aphids, and the rest on shell aphids and spider mites. Ladybugs, along with other leaf aphid killers, are the most important helpers in the garden.

Adult ladybugs hibernate outdoors, such as under foliage or dry grass.. In spring, ladybugs lay 10-20 eggs vertically in a group on branches or on the inside of a leaf close to aphid colonies. The larvae from the eggs go through 4 stages. They are usually painted in dark gray with a yellow or red pattern. At the end of the larval stage, ladybugs begin to pupate and, as a rule, acquire a yellow color. After leaving the pupa, the beetle needs another 2-3 days before it acquires the final color. It is especially important that both the larvae and the beetles themselves belong to the species of predatory insects and feed on aphids.

The seven-spotted ladybug known to us destroys up to 150 aphids per day, smaller species - up to 60. While still larvae, insects devour a total of up to 800 aphids. So, the female beetle destroys about 4 thousand adult aphids in her life.

Settlement in the garden.

• When using a ladybug as a plant protection, her development cycles should be taken into account!
• For wintering, provide an insect with a shelter (foliage, stones, bark, etc.).

Gallica.

Various species of the family of gall midges are better known to amateur gardeners as harmful insects (the larvae of a number of species develop in plant tissues, causing the formation of galls) than help in pest control. The body length of gall midges varies from 1 to 5 mm. Known pests in the garden include, for example, pear gall midge. Useful gall midges feed at the stage of aphid larvae. The most important species is Aphidoletes aphidimyza. The female (about 2-3 mm in size) lays 50-60 eggs in one life span of 1 week not far from the aphid colony. Orange-red larvae hatch on the 4-7th day. The latter bite the aphids by the legs and inject a paralyzing fluid. The bitten aphid dies and is used by the larva for food. After 2 weeks, a fully formed larva falls to the ground and turns into a cocoon on the ground. After 3 weeks, a second brood hatches, whose cocooned larvae overwinter on the ground and hatch in the spring as adults.

Settlement in the garden.

• No special conditions are required, except for the complete exclusion of the use of chemicals in the garden.

Ground beetle larvae.

Ground beetle larvae feed on vegetable fly eggs, small insects and their larvae, worms, and slugs.. These beetles are rarely seen in the garden during the day, they hide in shelters. The length of the ground beetle is up to 4 cm, it is very mobile. Many species cannot fly and therefore are active at night. The color of the ground beetle is the most varied: large black and completely yellow shimmering species are known.

The eggs hatch into larvae after a few days and hatch, depending on the species, 2-3 years before the pupa. After a pupal period lasting approximately 2-3 weeks, adult (developed) ground beetles hatch from them. Along with ground beetles, which live mainly on the ground, there are also arboreal and flying species. They feed on small insects and worms and therefore live in decaying organic matter, such as compost.

The adult lacewing hibernates in secluded corners, so sometimes it can be found in residential areas. During the wintering period, the insect may acquire a yellow or brown color, but in the spring it turns green again.

Slimy lion.

Along with the common lacewing, we also have about 42 species of secret lions, which, like the lacewing, belong to real lacewings. One of the most famous species has a wingspan (brown with a specific shape) of about 3 cm. Adults and larvae feed on aphids and contribute to the biological balance in the fight against this pest.

Settlement in the garden. They prefer areas rich in flowering plants. Green-eyed birds need a shelter for the winter in the form of small wooden houses stuffed with straw.

The use of lacewing for targeted biological plant protection in greenhouses and protected ground has been tested with good results. To do this, it is necessary to place 20 lacewing eggs for each square meter of surface, which can be purchased at special biological laboratories.

Riders.

Riders can hibernate as larvae, pupa, or adults.. For 1 time, the female lays about 30 eggs in the cabbage caterpillar. In total, she can lay up to 200 eggs. After the larvae hatch in the caterpillar, the shell of its body cracks, releasing the larvae, which turn into pupae a little later.

Settlement in the garden.

• It is necessary to arrange wintering "apartments" in tall grass or in roots under bushes, etc.
• The rider likes to settle in umbrella plants (dill, coriander, lovage, cumin, kupyr, etc.)
