A Study on Some Stored Products Infected by Caloglyphus Berlesei

Abstract

his experimental work was carried out to study the effect of infection by Caloglyphus berlesei on some stored products (soybean, wheat, maize and fishmeal) on some chemicals change. Also, Soybean, wheat, maize and fishmeal stored for three months, treated with basil and thyme at the level of 0.5%, 1.0% and 1.5% and infected with Caloglyphus berlesei in incubator at 28 ± 2 o C, mites count monthly. The results showed that infection stored soybean, and wheat by Caloglyphus berlesei decreased protein content, but fiber were increased. Stored maize and fishmeal infected by Caloglyphus berlesei decreased protein and fat but moisture, fiber, NFE (Nitrogen Free Extract) and ash were increased. Soybean, wheat, maize and fishmeal after stored population of Caloglyphus berlesei increased. Adding basil powder and thyme powder with concentration of 0.5%, 1.0%, 1.5% to stored products reduce the population of Caloglyphus berlesei. It was clear that adding thyme 1.5% gave the lowest number of Caloglyphus berlesei in different period compared with other groups.
