INFLUENCE OF INSECTICIDE BREEDING ON BIOLOGICAL PARAMETERS OF MUSCA DOMESTICA L. (DIPTERA: MUSCIDAE)

The goal of the current research was to evaluate the biological parameters of insects when they were exposed to insecticides for several generations. In the experiments, the adults of the house fly Musca domestica L. were feed with one of two insecticides (chlorfenapyr or fipronil) in each generation. The duration of development stages, fecundity, the weight of larvae, pupa, and adults, as well as the sizes of females and males, were evaluated. The statistical significance of differences in biological parameters was assessed by the non-parametric Kruskal-Wallis and Dunn criteria. The duration of the larva stages lasted 2.2 times more in the fourth generation of chlorfenapyr- and fipronil-exposure strains compared to the control laboratory strain of M. domestica. Increasing the period of preimaginal stages of the insect life cycle can be considered as a sublethal effect of insecticides.
