| Abstract | ||||
| This study aimed to evaluate the efficiency of hydrophilic silica nano-particles at 500 ppm concentration compared with recommended chemical insecticide “Malathion” against Callosobruchus maculatus Fab. (Coleoptera: Chrysomelidae) under laboratory stored conditions. C. maculatus is a major pest of cowpeas in Egypt. Hydrophilic silica-nano-particles showed that the number of C. maculatus, mortality were 99 ± 1.2, 96 ± 3.2, 100 ± 0.0 and 100 ± 0.0 % six, four, two months and zero time post treatment; respectively, reduced to 5 ± 4.2, 12 ± 6.2 , 24 ± 3.2 and 63 ± 1.2 in case of using Malathion. Biological parameters revealed decrease of egg number and seed damage % with hydrophilic silica nano-particles. This investigation recommends Silica nano-particles as an effective matter in control C. maculatus under laboratory condition with low damage in cowpea seeds. Also, we need more study on the effect of using different degrees of temperature during using silica nanoparticles on pest suppression. | ||||
