Abstract:
Zinc oxide nanoparticles (ZnO-NPs) have emerged as a promising tool in sustainable agriculture due to their unique properties and potential for pest management. This study evaluates the impact of different ZnO-NP concentrations (0, 50, 100, 200, and 400 ppm) on the reproductive parameters of Spodoptera frugiperda, a notorious pest affecting maize and other cereal crops. We assessed the effects on the percentage of ovipositing females, fecundity, and egg hatching percentage. The results reveal a significant decrease in reproductive parameters with increasing ZnO-NP concentrations. Specifically, the percentage of females ovipositing eggs dropped from 90% in the control group to as low as 32% at 100 ppm. Fecundity, measured as the total number of eggs laid, also declined from 1422.5 eggs in the control group to 409.2 eggs at 100 ppm. The hatching percentage of eggs showed a similar trend, decreasing from 93.4% in the control to 15.24% at 100 ppm. These findings suggest that ZnO-NPs can significantly impair the reproductive success of S. frugiperda, affecting both egg-laying capacity and hatchability. The substantial reduction in fecundity and hatching percentage indicates that ZnO-NPs could be effective in managing pest populations by targeting reproductive health. This research underscores the potential of ZnO-NPs as an alternative to conventional pesticides, offering a more environmentally friendly approach to pest control.
