| Abstract |
The effect of treatment wheat grains with petroleum ether, chloroform and acetone extracts of cinnamon on Sitophilus oryzae was determined and the LC50's and LC95's levels were estimated. Petroleum ether appeared to be the most effective against S. bryzae. Reproductive capacity of the weevil was strongly affected at the two levels of treatment. Chloroform extract was the most effective in reducing egg laying and adult emergence. The residual effect was also studied after different periods. Petroleum ether extract gave protection up to 8 weeks compared to 7 weeks in case of chloroform and acetone extracts. All tested extracts have slight reduction effect on both grain germination at the initial time arid at the end of storage period (11 weeks) and on weight loss of treated grains. Biochemical studied of some enzymes in S. oryzae showed that petroleum ether extract was the most effective in reducing the activity of amylase, trehalase, acid phosphatase and acetylcholinesterase.
