The role of the protection of beneficial insects in the garden

August 12, 2017 17:52 | General Information About Plants

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

Ladybug - well-known beneficial insects in the garden.It refers to the round beetles and, depending on the length is 4-9 cm. The most common Coccinella septempunctata.His name Beetle was 7 black dots on red elytra.But also there are beetles with elytra yellow and black dots or black beetles with bright spots or no.Also, the number of spots or drawing of wings can be varied.In total, we can find about 70 species of ladybirds, among which about 50 species feed on leaf aphids, and the rest - armor-clad aphids and spider mites.Ladybugs, along with other fighters leaf aphids are important helpers in the garden.

Adults ladybug winter on the open field, for example, under leaves or dry grass.Spring ladybugs lay 10-20 eggs on the branches of a group of vertically or on the inner side of t

he sheet near the colonies of aphids.The larvae from the eggs are 4

stage.they usually painted in dark gray with a yellow or red pattern.After the larvae stage ladybugs proceed to pupation and acquire, as a rule, yellow color.After leaving the beetle pupa must be 2-3 days before the acquisition of the final color.Particularly important it is that the larvae and beetles themselves belong to the species of predatory insects, aphids feed.Known

our seven-spotted ladybug consumes per day up to 150 aphids, smaller species - up to 60. Even as larvae, insects devour a total of up to 800 aphids.Thus, the female beetle kills for his life about 4 million adult aphids.

When using a ladybug as a plant protection should take into account the cycles of its development!

to provide wintering insect refuge (leaves, stones, bark, etc.).

gall midges. Different types of gall midges family better known amateur gardeners as harmful insects (larvae of some species develop in the tissues of plants, causing the formation of galls) than helping in the fight against the pest.The body length of gall midges varies from 1 to 5 mm.Known pests in the garden belongs to, for example, pear midge.Useful as midges feed on aphids larvae stage.The most important species is Aphidoletes aphidimyza.The female (the size of about 2-3 mm) lay a single life term of 1 week, 50-60 eggs near aphid colonies.On the day of hatch 4-7- orange-red larvae.The last bite aphids per stem and inject paralyzing liquid.Bitten aphid larva dies and is used for food.After 2 weeks of fully formed larva drops to the ground and turns on the ground in a cocoon.After 3 weeks of the second brood hatches, whose larvae overwinter in cocoons on the ground and hatch in the spring, when he was already adult.

No special conditions are required, in addition to completely eliminate the use of chemicals in the garden.

larvae ground beetles feed on the eggs of vegetable flies, small insects and their larvae, worms, slugs.These beetles are rarely seen during the day in the garden, they are hiding in shelters.The length of the ground beetle up to 4 cm, it is very mobile.Many species can not fly and therefore active at night.Color carabids very varied: there are large black and yellow brand shimmering views.Adult insects overwinter in the garden in secluded corners protected, for example under the house or the woodpile.Large ground beetles lay their eggs at 40-60 separately shallow hole in the ground.Of the eggs hatch in a few days the larvae.A couple of weeks the larvae burrow into the ground, where after a few days (or after wintering) pupate.After a period of pupa lasts approximately 2-3 weeks of them hatched adults (advanced), ground beetles.Along with ground beetles that live primarily on the ground, there are also wood and flying species.They feed on small insects and worms, and therefore live in decaying organic matter such as compost.

should provide a haven of ground beetles (leaves, sawdust and shavings, small heaps of stones), they live in the open ground, hiding sometimes earthy crevices.

Pesticides - the worst enemy of ground beetles!

hoverflies are important in horticulture because their larvae feed on aphids.Larvae develop in different conditions - soil, liquid manure or plants.Visually similar to a wasp hoverfly, the length of an adult - 8-15 mm.Hover feature, reflected in their name - they are in flight, as it were hang in place, while uttering a sound, remotely reminiscent of the sound of water.Delaying the eggs occurs in aphid colonies.Eggs magnitude of 1 mm, oblong, white.Hatched larvae have no legs and move like snails.They are colored in white or yellow color similar to the fly larvae.

For hunting for aphids hoverflies use their hooked jaws that firmly hold the prey by sucking it.The development of the larvae to pupa stage lasts for 2 weeks.During this time, the larva eats up to 700 aphids.The larvae of hoverflies are active mostly at night and go hunting until twilight.The pupal stage is experiencing a hoverfly in the shell in the form of droplets, are placed near the colonies of aphids on the leaves or on the ground.Certain types of output for several generations, most - up to 5 per year.In some species overwinter females as well as larvae or pupae.Sami hoverflies feed on flower and honeydew, and the secretions of aphids.

hoverflies most suitable areas with flowering plants, but not well-kept lawns.Especially like hoverflies plants, blooming yellow flowers.

for overwintering hover can leave small wooden boxes filled with dry grass or shavings.

Goldeneye along with ladybirds is the enemy of aphids.In our gardens the most frequent kind of green with yellow eyes.The name of the beetle got it over the eyes.The adult has a wingspan of up to 3 cm. Green oblong insects are transparent veined wings in the form of a house, putting them at the bottom of a long torso.

female lays about 20 eggs separately or greenish band on the bark or leaves.Hatched larvae develop, depending on weather conditions for 2-3 weeks.Their length of only 7 mm, jaw long, sickle-shaped and sharpened.Larvae feed on small insects, especially aphids.Some individuals are able to destroy during the development of up to 500 aphids.

After 18 days, the larvae hide in a safe place, and turn wrapped in white round cocoon.After the release of the lacewing cocoon begins the next generation.Just a year may appear 2 generation.The adults feed on, as a rule, honeydew and pollen, on occasion, not disdaining small insects.Wintering adult lacewing in the nooks, because sometimes it can be found in a residential area.During wintering insect can get yellow or brown color, but spring turns green again.

Tliny lion

Along with lacewing ordinary, we found about 42 more species tlinyh Lions, who, like lacewings belong to this lacewing.One of the most known species has a wingspan (brown specific form) of about 3 cm. The adults and larvae feed on aphids and contribute to the biological balance in the fight against this threat.

Prefer rich flowering plants sites.

Zelenoglazkam necessary shelter for the winter in a small wooden house, stuffed with straw.

Using lacewing targeted for biological protection of plants in greenhouses and greenhouses were tested and gave good results.To do this, on every square meter of surface to put on 20 lacewing eggs, which can be purchased in special biolaboratories .:

Riders develop as parasites on various host, which may be many insects, except spiders.For gardeners riders are of great importance, as they destroy the butterfly caterpillars, larvae of flies and aphids.Appearance riders resemble wasps and in most cases have a dark or variegated color.Their size varies, ranging from less than 1mm to over 10mm.As an example, mention should be made 2 different types of rider, of particular importance.The first type is parasitic on caterpillars, cabbage butterfly, the second - on aphids.Eggs rider puts on the insect and its larvae, caterpillar, or in their bodies using a special sting that lightning pierces the victim's body.Of the eggs hatch the larva of the respective type of rider and sucks the "host."

Riders can hibernate as larvae, pupae or adult.For 1 time the female lays about 30 eggs in the caterpillar cabbage.In total, she can lay up to 200 eggs.After hatching, larvae caterpillar shell of her body bursts, releasing larvae that later turn into pupae.

Species parasitizing aphids lay eggs in the body of the aphid.Larvae emerging from eggs, sucking aphids from inside, so feeding and pupate in a cocoon of fine web.After pupation the rider leaves the cocoon through a small hole in the shell aphids.From each female affects about 200 aphids.The development of insect from egg to pupal stage lasts about 10 days, so that several generations can occur throughout the year.Aphids, startled riders, has a distinctive bronze color, and a cylindrical body.

necessary to arrange wintering "apartments" in the tall grass or the roots of a shrub, etc.,

Rider loves to settle in the umbrella plants (fennel, coriander, lovage, caraway, chervil, etc.).

common earwig, relating to the order earwig, well-known gardeners.body length 3.5 to 5 mm, front wings solid rear - webbed.There are also wingless forms.Impress her claws are located at the back of the torso.Earwig hunts mainly at dusk and at night, and during the day hiding in the dark narrow gaps.

Exterminating harmful insects, such as Georgievich-Ganov woodlice, earwig can damage tender young plants dahlia;

spring and autumn female lays in a hole that pulls itself up to 100 eggs, protects and cares for its offspring - the eggs first, and later on the larvae.Earwigs overwinter in shelters - in the bark of trees, buildings cracks in the soil of flower pots filled with fine chips or any other material, such as moss.

as shelters can use flower pots filled with wood shavings, hay or moss.These pots are set between vegetable crops and are posted on trees, in winter pots should be cleaned out, and in the spring to fill again.

digging tree trunks of trees contributes to normal insect activity.Often as earwigs are looking for a shelter in the winter it is under trees, in its fallen leaves.

predatory bugs belongs to a class of weevils.Its various types have certain sources of supply.For some, it is the juice of a plant, for others - the insects.For the gardener are primarily interested in the latter, which, among other things, destroying aphids.These are spineless and false bugs, including some species feed primarily spider mite.

Flowering bugs - small predatory insects 3-4 mm long.For 1 time the female lays up to 8 eggs, mainly on the edges of the leaves.For the year bedbugs output 2 generations, and in areas with warm climates, even 3 - predatory bugs hibernate by adults.Larger species of flowering bugs feed on midge larvae also.
