Does behaviour play a role in house fly resistance to imidacloprid-containing baits? uri icon

abstract

  • The objective of this research was to examine the role and type of behavioural mechanisms that function in house fly, Musca domestica L. (Diptera: Muscidae), resistance to an imidacloprid-containing commercial fly bait, QuickBayt() , using an insecticide-susceptible and an imidacloprid-resistant strain. Mortality and feeding behaviour were observed through choice bioassays of three post-imidacloprid selected house fly generations to determine whether flies would consume the bait in the presence of an alternative food source. Mortality rates in choice containers progressively decreased in post-selection flies as QuickBayt() no-choice selections proceeded. There were no differences between the proportions of flies observed contacting QuickBayt() and sugar, respectively, a finding that eliminates repellency as a mechanism of stimulus-dependent behavioural resistance. However, differences in QuickBayt() consumption and subsequent mortality between choice and no-choice containers provided strong support for the evolution of consumption irritancy- or taste aversion-related behavioural resistance. The results of this study support the responsible rotation of insecticide bait formulations for house fly control.
