Control of the Khapra Beetle Trogoderma granarium (Everts.) (Coleoptera : Dermastidae) using Nanoparticles of Neem Leaf Extract

The effect of four concentrations (0, 3, 1, 5%) of the nanopesticide of neem leaf extract was tested on the four stages of hairy grain beetle at five time times (1, 2, 3, 5, 7) days. The results showed that there is Significant differences between the three concentrations (1, 3, 5) compared to the fourth concentration, which represents the control treatment, where it was noted that the hatching rate of the egg stage was the lowest at the 5% concentration. As for the larva and pupal stage, the killing rate was highest at the 5% concentration on the second day While the highest killing rate for adult females was at a concentration of 5% on the first day of the treatment procedure, from this it becomes clear that the higher the concentration of the pesticide, the higher the killing rate.
