The effect of Imidacloprid and nano-Imidacloprid against Sitophilus granarius under laboratory and store conditions

Description

Abstract: The effects of some natural Imidacloprid and nano-Imidacloprid were tested against the grain weevil Sitophilus granarius under laboratory and store conditions. Results obtained show that the percentage of larval mortality of S. granarius was 59% and 89% after treated with Imidacloprid and nano-Imidacloprid compared to 0% in the control. When the grain weevil S. granarius was treated with the higher concentrations, at 3% the eggs laid/female for the corresponding tested Imidacloprid and nano-Imidacloprid were recorded as 31 ± 1.9, and 5 ± 1.4 eggs/female as compared to 199 ± 6.9 eggs/ female in the control.
