【 摘 要 】

Pestcontrol services dealing with mass pests such as locusts and grasshoppers areforced to use insecticides of various origins to prevent crop damage. In most cases, mainly chemicalinsecticides are used. This method of regulating pest populations has manynegative consequences. As a result of chemical treatments with broad-spectruminsecticides, not only pests are killed, but also non–target organisms,primarily entomophages and pollinators. One of the alternatives to the chemicalmethod of control is the use of biopesticides based on entomopathogenicviruses, bacteria, and fungi. The impact of the biopesticide "Entolek KPlanteco®" based on the fungus Akanthomyces lecanii on differentspecies of locusts, grasshoppers, and katydids was evaluated in soybeanplantings of southeast Kazakhstan. Locust and grasshopper mortality was 70% onthe 3rd day after treatment and 98% on the 7th day, whilekatydid mortality on the same days was 50 and 70% respectively. Thus"Entolek K Planteco ®" proved efficient for controlling harmfullocusts, grasshoppers and katydids. This is especially important in sensitiveareas where the use of chemical insecticides is legally prohibited (waterprotection zones, specially protected natural areas, agricultural land forgrowing organic products.
