Abstract
In 2018-2020, domestic and foreign biological insecticides were tested against three species of herd locusts; Dociostaurus maroccanus Thunb., Locusta migratoria migratoria L. and Calliptamus italicus L. Scientific research was carried out in the main regional locust foci in Almaty, Zhambyl, Turkestan and Kyzylorda regions. The spring-autumn examination of locust pods was carried out according to generally accepted methods in entomology. The examined deposits of pods were recorded by a GPS device. Tested drugs: 1) Actarophyte 1% is a complex of natural avermectins, 2) Actarophyte 1.8% is produced from the same soil fungus, DV - Bifenazate. 3) Green barrier, S.P. is developed on the basis of the fungus Beauveria bassiana, 108 CFU/g. 4) Mikolar B, Mikolar M. are based on strains of entomopathogenic fungi of boveria and metarizium from the collection of the biotechnology laboratory of Kazniizikr LLP. 5) Novacrid is a drug manufactured by Elephant Vert. The drug is pure spores of the entomopathogenic fungus Metarhizium anisopliae. 6) Greene gold, 0.3% by weight (azadirakhtin, 0.3%). In general, all the tested means have shown one or another effectiveness in the fight against locust larvae. The most rapid and strong toxic effect was shown by the drug actofit based on avermectins - up to 90-99% mortality on day 1-3, up to 100% mortality on day 10. The herbal preparation Greene Gold showed a slightly smaller effect on all three types of locusts. Mycola B and Mycola M did not show high efficacy, which is due to the lack of preparation forms. In experiments on the use of the So-450 sprayer and the Gaia 160 AG UAV as a treatment technique against locust larvae, identical results were obtained in all experiments, which will further simplify the test procedure using only one of the types of equipment, depending on the circumstances.
