Abstrakt: This review briefly summarizes the data on the virulence mechanisms of entomopathogenic ascomycetes and the defense reactions of insect hosts. Special attention is paid to the influence of environmental factors (temperature, toxicants, concomitant infections, symbiotic microorganisms and parasitoids) on the physiological aspects of the relationship between insect hosts and entomopathogenic fungi. Based on our analysis, it may be supposed that prolonged influence of stress factors (low temperatures, natural and synthetic toxicants, bacterial infections) suppresses the set of cellular and humoral defense reactions and may also induce ontogenetic disorders in insects, thereby increasing their susceptibility to fungal infections. Understanding these mechanisms is important for the development of new approaches to biological control of economically important insect species. [ABSTRACT FROM AUTHOR]
