| Abstract | ||||
| Green synthesized nanoparticles have been studied as new and more effective biopesticides against insects of medical importance and this for their eco-friendly aspects. In the current study Moringa oleifera leaf extract (Mo-LE) was used to synthesis silver nanoparticles (Mo-AgNPs) and zinc oxide nanoparticles (Mo-ZnONPs). Low concentrations of Mo-LE, Mo-AgNPs andMo-ZnONPs showed the larvicidal and pupicidal toxicity against Musca domestica. In larvicidal bioassay, the values of LC50 were 16.50, 2.03 and 6.41 mg/ml for Mo-LE, Mo-AgNPs andMo-ZnONPs, respectively. In addition, the LC50 was determined against pupae, which were129.77, 9.604 and 17.10 mg/ml for Mo-LE, Mo-AgNPs andMo-ZnONPs, respectively. Moreover, treatment larvae with LC50's of Mo-LE, Mo-AgNPs andMo-ZnONPs produced a significant reduction (P<0.05) in the fecundity of female and a highly significant reduction (P<0.01) in the egg hatchability. The total protein content and activities of nonspecific esterases, acetylcholine esterase, and glutathione S-transferase enzymes were significantly declined after larvae had fed on LC50 Mo-AgNPs andMo-ZnONPs treated diets as compared with the control. This study indicates that it is feasible to use M. oleifera synthesized nanoparticles as effective candidates to develop newer and cheap control tools for immature stages of M. domestica. | ||||
