FUNDAMENTAL ASPECTS OF THE APPLICATION OF ENTOMOPATHOGENIC FUNGUS BEAUVERIA SP. AS A PERSPECTIVE AGENT FOR PLANT BIOPROTECTION Maulenova R.S. al-Farabi Kazakh National University mraushans@gmail.com The large-scale use of pesticides has a number of significant shortcomings, the most important of which are the emergence of resistant pest populations and environmental pollution. Due to the deterioration of the environment and the problem of environmental protection, the current and important task of government is the widespread use of biologics of domestic production in the protection of plants instead of chemical pesticides. Entomopathogenic fungi are an inexhaustible biological resource of natural and selection strains with a selective spectrum of virulence for individual groups of arthropod pests and most of them are harmless to the environment. Therefore, the creation of mycoinsecticides is a direction in biotechnology, which in many countries of the world shows unflagging interest. It is known that fungi were the first organisms proposed by I.I. Mechnikov and I.M. Krasilshik for factory production in order to use them against harmful insects at the end of the last century. Several species of fungi are recommended for mass production in the world, of which Beauveria bassiana (Bals.) Vuill. is ranked at the first place. At present, there are no biological preparations based on entomopathogenic fungi in Kazakhstan to control the number of harmful arthropods, and locusts in particular. Kazakh Scientific Research Institute of Plant Protection and Quarantine together with the All-Russian Institute of Plant Protection had the projects on screening new strains of the Beauveria fungus on the basis of virulence on the Moroccan locust, on sucking pests in greenhouses (in manufacturing conditions), assessing the biological activity of strains in the 182 field, combating with the Colorado potato beetle using local strains, determination of the age and phase sensitivity of the Colorado potato beetle to selected strains, and also the efficacy of strains of the entomopathogenic fungus of the genus Beauveria in suppressing the number of larvae of the Colorado potato beetle, etc. Thus, the entomopathogenic fungus B. bassiana is attracting increased attention as a potential tool for biological control of insect pests. Understanding the mechanisms of fungal pathogenesis in insects will provide a rational basis for strain selection and improvement. Scientific adviser: Ph.D. of Biology and Biotechnology Akimbekov N.
