Abstract :In the present study, the effects of deltamethrin on cell-mediated immune response and genotoxic damage of Galleria mellonella insert ignore into journalissuearticles values(Lepidoptera: Pyralidae); were investigated. Different concentrations of deltamethrin insert ignore into journalissuearticles values(5, 20, 50, 100, and 150 µg); were administered to G. mellonella at 24, 48, 72, and 96 h. Five types of hemocytes were identified in G. mellonella: prohemocytes, plasmatocytes, granulocytes, spherulocytes, and oenocytes. Total hemocyte counts insert ignore into journalissuearticles values(THCs); were significantly affected by deltamethrin. At 72 h, THCs of the treated group had significantly decreased compared with the control groups at high deltamethrin concentrations insert ignore into journalissuearticles values(50, 100, and 150 µg);; however, at 96 h, THCs had significantly increased at deltamethrin concentrations of 100 and 150 µg. Micronucleus formation was significantly affected by deltamethrin; in particular, high concentrations of deltamethrin insert ignore into journalissuearticles values(100 and 150 µg); caused an increase in micronucleus formation at all time points. We conclude that deltamethrin affected THCs and caused the induction of micronucleus formation via genotoxic damage in G. mellonella.
