Entomopathogenic activity of bacterial and viral strains from the bioresource collection “State Collection of Entomoacariphages and Microorganisms”

Abstract

As a result of a series of experiments to study the entomopathogenic activity of bacteria and viruses from the “State Collection of Entomoacariphages and Microorganisms”, it was revealed that the large wax moth Galleria mellonella L. it is sensitive to new strains of bacteria and viruses. In the future, the strains can be used in the subsequent stages of screening of microorganisms that are promising as agents of biological pest control. The maximum biological efficacy on the fifth day against the tested insect was observed when using bacterial strains Bacillus spp. BZR 1159 (94.6%) and BZR 936 (95.0%) and a granulovirus strain of the codling moth (CpGV) BZR L-5 (100%). Larvae of G. mellonella L were susceptible to melanization in the process of infection with new bacterial and viral agents.
