Chernyshev, О.V.
The data on the regulatory role of natural populations of entomophagous in the integrated protection of greenhouse plants from sucking pests using mainly low-emission insectoacaricide, which provides for the replacement of highly toxic compounds insectoacaricide 3–4 grade of toxicity in the winter, the use of drugs of biological origin in the spring and early summer for reduce the number of scale insects, aphids, mites, mealybugs, whiteflies and create optimal starting conditions for the settlement of natural populations of entomophagous greenhouses, maintenance and conservation of natural populations afidius, afidimiza and encarsia against aphids and whitefly in the summer and autumn. The developed system was tested in the greenhouses of citrus, camellias, azaleas, cymbidium, crotone, bromeliads and orchids. It allows you to reduce the amount of spraying chemicals against scale insects and mealybugs on 3–4, and against aphids, mites and whiteflies – to 8. This is achieved by active protection against major pests, and to maintain high decorative collections while reducing the negative impact on them of pesticides .
