The power of Drosophila genetics in studying insect toxicology and chemical ecology

Abstract

AbstractInsect toxicology and chemical ecology are inherently interconnected disciplines, both dedicated to unraveling the intricate relationships between insects and the diverse array of chemical compounds that pervade their surroundings. Drosophila melanogaster, owing to its genetic and physiological similarities to other insects, serves as a robust model system in the study of insect toxicology. Moreover, state-of-the-art techniques in Drosophila neurobiology have extensively probed the chemosensory system of insects, providing significant insights into their adaptation to chemical environments. In this review, we emphasize the advancements achieved through the application of Drosophila genetics in investigations spanning both of these fields, significantly enhancing our understanding of the mode of action and resistance mechanisms of insecticides, as well as unraveling the molecular and cellular mechanisms underlying insect chemosensation and associated behaviors. The profound insights derived through this tiny fly not only enrich our understanding of the broader world of insects but also hold the potential to develop more effective and sustainable strategies for pest management.
