摘　　要：The house fly,Musca domestica,is a cosmopolitan species known for its pestif-erous nature and potential to mechanically vector numerous human and animal pathogens.Control of adult house flies often relies on insecticides formulated into food baits.How-ever,due to the overuse of these baits,insecticide resistance has developed to all insecti-cide classes currently registered for use in the United States.Field populations of house flies have developed resistance to imidacloprid,the most widely used neonicotinoid in-secticide for fly control,through both physiological and behavioral resistance mecha-nisms.In the current study,we conducted a comprehensive analysis of the inheritance and dominance of behavioral resistance to imidacloprid in a lab-selected behaviorally re-sistant house fly strain.Additionally,we conducted feeding preference assays to assess the feeding responses of genetic cross progeny to imidacloprid.Our results confirmed that behavioral resistance to imidacloprid is inherited as a polygenic trait,though it is inherited differently between male and female flies.We also demonstrated that feeding preference assays can be instrumental in future genetic inheritance studies as they provide direct insight into the behavior of different strains under controlled conditions that reveal,interactions between the organism and the insecticide.The findings of this study carry significant implications for pest management and underscore the need for integrated pest control approaches that consider genetic and ecological factors contributing to resistance.
