 Behavioral Resistance to Insecticides

Behavioral resistance of insects to insecticides has been documented for nearly 70 years, yet little research has attempted to understand the mechanisms conferring this resistance. My dissertation research aimed to elucidate house fly (Musca domestica L.) behavioral resistance to the neonicotinoid insecticide imidacloprid. This research was the first of its kind to examine the mechanisms conferring behavioral resistance to an insecticide in the house fly (Hubbard and Gerry 2020, Hubbard and Gerry 2021).

I am currently investigating the nuanced behavior that results in behavioral resistance to imidacloprid. I plan to study fly feeding preferences when exposed to varying concentrations of imidacloprid, the stability of behavioral resistance. Additionally, interested in exploring the prevalence of behavioral resistance across the United States. 

Investigation of the Biology and Behavior of the Little House Fly (Fannia canicularis L.)

The little house fly, Fannia canicularis (L.), is a significant pest associated with livestock and animal systems worldwide. This species commonly develops in poultry production systems. The males of this species are a nuisance to people because they form mating swarms in enclosed spaces.

The pest status of F. canicularis has not lessened because it was identified as a critical arthropod pest of veterinary importance over 50 yr ago. During this period, there has been little research progress to control this pest, especially when compared with other filth fly species.

I am interested in investigating the biology, behavior, and pest status (including nuisance and pathogen transmission risk) of this neglected fly species in order to develop control methods that can be used to control this fly species.
