Abstract
The review of foreign literature analyzes the effects of mycoinsecticides on the adults and larvae of the house fly. The time of death of 50?% of individuals at a high concentration of 1?·?109 conidia varies from 3.8 days for Beauveria bassiana and from 5.2 days for Metarhizium anisopliae. The time required to kill the host is usually 4–6 days for both species of fungi. Currently, more effective strains of fungi are developing in the world. Further increases in kill indices can be achieved by genetically modification of pathogen to accelerate its penetration through the cuticle. The susceptibility of house fly adults to sugar baits with B. bassiana conidia has been established. The reasons for differences in the effectiveness of B. bassiana against house fly larvae (from 0?% to 70?% mortality of larvae) are investigated, for example, variations in strain virulence, fungal cultivation method, conidial dose or concentration, fly instar, nutritional status of the host larvae, method of exposure, properties of the substrate for larval cultivation and differences in the susceptibility of fly cultures. Several mycoinsecticides assigned to control the house fly are produced abroad. Domestic developments are needed for use of entomopathogenic fungi against resistant flies in Russia. Keywords: mycoinsecticides, entomopathogens, house fly, Beauveria bassiana, Metarhizium anisopliae.
