New strategies for control of insecticide-resistant german cockroaches

Abstract

In a review of foreign literature, the issues of biological methods for controlling synanthropic cockroaches, including the use of entomopathogenic fungi such as Metarhizium and Beauveria, are considered, due to high biodegradability and species-specificity, is a potential alternative to the chemical method. It has been shown that the combination of chemical and biological agents in cockroach control can slow down the emergence of insect resistance and enhance the insecticidal effect. The densonucleosis viruses BgDNV and PfDNV may be required for the biological control of cockroaches due to such features as rapid replication, high specificity, and pathogenicity for the host. In view of the close relationship between symbiotic microorganisms and host physiology, insect control strategies using transgenic symbionts have become the subject of research. Significant differences in the composition of the intestinal microbiota between the pyrethroid-resistant and insecticide-susceptible strains of the German cockroach were found. A new potential direction for insect resistance management has been identified. Keywords: entomopathogenic fungi, German cockroach, microbiota, symbiotic microorganisms.
