Effect of Food Treated with Silica Gel on Three Types of Storehouse Insects

Abstract

Abstract Silica gel was tested as a protective material for the seeds of cowpea, wheat and groats and mixed with five concentrations (1-5%) against the three insect species of stock and this affected their killing, the development of their first generation and the rate of loss in food weight after a month of treatment. The results showed that silica gel A generation that caused a killing rate of 100% for the southern cowpea beetle after 144 hours of treatment and for all the concentrations used, and a killing rate of 100% for the capillary beetle at a concentration of 5% and after 192 hours of treatment from the treatment at a concentration of 5%, while the killing rate reached 10% in the rusty flour beetle after 192 hour at a concentration of 5%. According to what was mentioned above, this study came for the purpose of identifying the effect of silica gel on three types of storage insects, which are the southern cowpea beetle Callosobruchus maculates, Trogoderma granarium and the rust flour beetle Tribolium castaneum.
