الملخص الإنجليزي

This study was conducted to evaluate the effect of crude powders at (0.4 and 0.6) % concentration in addition to petroleum ether, chloroform, ethanol alcohol and water extracts at (0.10 and 0.20) % concentration of Pisum sativum and Glycine max seeds in Population density of khapra beetle, and loss of grain weight due to infection.

Results denoted that the population density of Trogoderma granarium and the weight loss of grains differ according to kind of powder and extract and the concentration use of its.

Generally, all of them had significant effects in decreasing the population density and then depression the weight loss.

The of Pisum sativum and Glycine max powders were superior than extracts in limiting of reproduction and growth of Trogoderma granarium and the pea seed powder at 0.6% concentration was superior between them, where the total number of all stage was 216.33 individuals versus to 972.67 individuals in control and causing of lowest weight loss of 3.78 gm %.

For extracts, the petroleum ether extract of Glycine max seed at 0.20 % concentration was the best in its effect on the reproduction and growth of Trogoderma granarium population which gave the lowest number of individuals which was 362 and causing in the lowest percent weight loss of 6.44 gm %.
