| Abstract | ||
| Nano particle of Zinc oxide size (5nm) and (100nm) and silver nano Particle (100 nm) were used in This study at concentrations (100, 250, 500, 750 and 1000) ppm to know their effect on some biological aspects of the southern cowpea beetle Callosobruchus maculatus (Fab.) through treating the food of these insects (chick pea seeds) by these nanoparticles. The study proved that the above Particles had a significant effect on the parentage of eggs hatching as it reached 49.4% compared to 86.9% of control Also, the some treatment led to high at 1000 ppm concentration mortality percentage 98%. Moreover, the treatment had an effect on the pupa stage and on the period of insect development, which was elongated significantly in the treatments of the zinc oxide size (100 nm). The maximum period was 40.60 days at the concentration of 1000 ppm Which differed significantly from its comparative coefficient. The productivity of insect decreased significantly to 16.6%in zinc oxide nano Particle size (5 nm) clearly. This study showed that the treatments effected the vitality of the first-generation females as the percentage of egg hatching decreased to 50% more than that egg retention was observed on these females which reached to 50% at treatment of zinc oxide size (5 nanometer). | ||
