Abstract

More than 150 locust species are widespread in Uzbekistan, among them about 15 species can cause damage to agriculture every year, and they considered harmful. Among the harmful species of locusts, there are 3 species that can make a swarms. We have researched swarming locusts in the Andijan region of the Republic of Uzbekistan. Various types of chemical and microbiological insecticides are using to control of swarming locusts. In Uzbekistan, mainly used insecticides based on the Pyrethroid and Neonicotinoid groups. We have provide experiments to check the biological efficiency of insecticides "Aikido-Super" 10% e.c. and KARAT IKS 20% c.s. based on lambda-cygalothrin in various doses. According to the results of the experiment, insecticide Aikido-Super 10% e.c. and KARAT IKS 20% s.c. showed 97.6 and 96.3% biological efficiency at consumption rate  of 0.065 and 0.0375 l/ha.
