ABOUT THE RESULTS OF TESTS OF BIOPREPARATIONS AGAINST HARMFUL ENTHOMOFAUNS OF WALNUT FRUIT FORESTS

Abstract

           The article is dedicated to the research of the leaf-eating phytophages of the walnut forests of Kyrgyzstan: cherry slimy sawfly (Coliroa limacine Retz), oak mining sawfly (Profenusa pygmaea klug), gypsy moth (Lymantria dispar L.). The subject of the research is the effect of biological preparations of the type Bactocide VK and Entolek (developed in Russia) on the number of individual pests of leaf-eating phytophages.Modern methods of pest control in walnut fruit forests still use chemical insecticides extensively. Their advantage is a high speed of action and effectiveness; also, when using chemical preparations, insect pests are often able to develop resistance to insecticides, which is expressed in a change in the permeability of the covers, detoxification and a change in sensitivity to insecticides. Quantitative and experimental research methods were used in the research. Field tests were carried out in field and laboratory conditions in the vicinity of the city of Jalal-Abad and the arboretum of the Jalal-Abad National Center of the Southern Branch of the National Academy of Sciences. The results of the use of the preparations Bactocid VK and Entolek showed 96% -100% efficiency in the fight against larvae of oak mining sawfly and cherry slimy sawfly. According to the results of the research, it is recommended to register drugs on the territory of the Kyrgyz Republic to combat leaf-eating phytophages.
