Imago and larvae are active, they destroy the caterpillars of the American white butterfly, the Colorado potato beetle (imago destroys an average of 72 eggs or 15 second-instar larvae per day), etc. The perillus destroys the larvae of the Colorado potato beetle and some leaf beetles. During its development, one perillus larva sucks out an average of 240-250 Colorado potato beetle eggs. Currently, methods of mass breeding and methods of releasing these types of predatory bugs are being developed in Russia. The most extensive order of beetles in terms of the number of species also has many predators — omnivorous and specialized. There are especially many entomophages in such families as ground beetles, ladybirds, carapuses, soft-bodied, dead-eaters and others.
For example, the golden-point ground beetle, living in open spaces, actively destroys caterpillars of the meadow moth and gnawing scoops, as well as larvae and pupae of the Colorado potato beetle. The large Crimean ground beetle usually feeds on snails, including grape ones, which, trying to defend itself, is drawn into the shell, releasing a light foam at the same time. The alichora double—striped staphylin beetle is one of the natural enemies of agricultural pests. The imago beetle is eaten by the eggs and larvae of many phytophages, and the larvae parasitize the spoonbills of cabbage, onion, winter and other flies. In the order Reticuloptera from the family of golden—eyes, the common golden-eye is a ferocious predator. Imagos prey on many insects, and their larvae eat aphids. The larvae of the golden-eyed beetle also destroy the eggs of the Colorado potato beetle. This effective entomophage is specially bred in industrial bio-laboratories to control harmful insects of vegetable and green crops in protected soil. A relatively small group of camels is also represented by voracious predators. Living in forests, they destroy many aphids, caterpillars, bark beetles, sawfly larvae, and their larvae, developing under the bark, feed on eggs, larvae, and pupae of bark beetles, barbels, golden moth, and others. The order Hymenoptera includes many representatives used in biometrics. The family of horsemen is especially rich in parasites.
The talless rider, possessing a long ovipositor, searches for larvae of the horntail, a pest of tree species living deep in the trunks, and lays eggs in them. The female apanthelis (about 3 mm in size) lays up to 75 eggs in the caterpillar of the cabbage white. Ophion yellow parasitizes pine silkworms, pine, winter, exclamation scoops and many others. The bent sickle parasitizes the caterpillars of the pine owl, pine hawk moth, grass cocoonworm and other species. Aphelinus was first imported to Russia from Italy in 1926 to extinguish the foci of the most dangerous pest of apple trees — blood aphids. The introduction was successful in the very first year. Now the parasite has successfully spread throughout the range of the blood aphid. Encarsia formosa was introduced from Canada in 1960 as a specialized parasite of greenhouse whitefly larvae and is now being successfully bred in industrial biological laboratories. Representatives of the genus trichogramma are especially widely used in the practice of biomethod. The sandy ammonophila from the burrowing family successfully develops at the expense of winter caterpillars and other scoops, and sometimes locusts and moths. Thus, the larvae of the phytomyza mining fly feed on the infestation, a flower parasite of many valuable technical fodder and vegetable crops.
