The common green lacewing (Chrysoperla carnea) is one of the most effective biological agents in the control of various pests.
In natural conditions, the insect is widely distributed in many countries of Europe, Asia and other continents. It is a broad polyphagous that feeds on many species of insects and mites.
In order to increase their numbers in agroecosystems, goldfinches are applied by the method of seasonal colonization. In the spring, at the beginning of the development of pests (aphids, young larvae of butterflies and beetles, mites, etc.) the rate of consumption is usually 1500–2000 pieces per 10 decares of area. It is sown manually in the form of textile strips or discs on which the green lacewing eggs are glued (see photo).
