Influence of microbial symbionts on chemoreception of insect hosts

Abstract:

Symbiotic microorganisms regulate host chemical communication by affecting the synthesis and perception of insect semiochemicals, which in turn influences insect communication, defense, predation, and dispersal behavior. The effect of microbial symbionts on host chemical communication facilitates the spread of microorganisms, but could be beneficial or detrimental to the host, and provides the impetus for the co-evolution of symbiotic systems. In this paper, we review recent studies on the effects of microbial symbionts on insect chemoreception and their mechanisms, and analyze their evolutionary significance, aiming to provide supplementary information to the theory of insect chemical ecology and provide insight into the development of new pest control strategies.
