| Abstract | ||||
| The house fly, Musca domestica transmits many diseases to humans, so that controlling it without side effects on human health is extremely important. Therefore, the current study aimed to compare the toxicity of tested chitin synthesis inhibitors (CSIs) lufenuron, flufenoxron, and hexflumuron against 3rd instar larvae of the house fly, and to assess the lethality effects by serial concentrations (1000, 500, 250 & 125ppm) of each tested compound on the developmental parameters and growth indices of the immature stages of M. domestica. The least toxicity values of sub-lethal concentrations (LC25, LC50 & LC75) displayed for lufenuron (158.23, 332.46 & 698.56, respectively). Also, hexaflumuron scored (64.06ppm at LC25), followed by flufenoxuron (140.95 & 283.62ppm at LC50 & LC75, respectively). Flufenoxuron was the most toxic, followed by hexaflumuron and lufenuron. CSIs showed a toxic efficiency on 3rd instar larvae of M. domestica by decreasing developmental and growth indices rates at higher concentrations of each one. Flufenoxuron exhibited a marked significant decrease in larval development and growth index rates (15.50 & 2.71% at 1000ppm, respectively), highest water loss (69.79%) compared to hexaflumuron and lufenuron. Flufenoxuron was the most toxic one against pupae as compared to others, it prolonged pupal duration (14.71day) and induced pupal water loss (53.77%), its pupation, developmental and weight rate reduced (17.5 & 6.8%, & 53.77mg respectively). But, growth index did not cause mortality with the highest concentration. Adult emergence displayed non-adult emergence and a high percentage of the malformation rate at 1000ppm when treated with flufenoxuron compared to other compounds. | ||||
