| Abstract | ||||
| The effectiveness of Prosop < /em>is luflnora (S.W) D.C. seed extracts against Sitophilus oryzae (L.) insect reared on wheat grains was investigated in laboratory bioassays. AU tested plant extracts (petroleum ether. chloroform, and acetone) effectively controlled adult insects and their toxicity Le95 and LCso values averaged (12.0, 5.8mllkg) for acetone < petroleum ether (8.0, 4.1mllkg) < chloroform (6.3, 2.2ml/kg), respectively. A high significant effect on oviposition (P< 0.05) was found for all tested extracts at LC~o levels, while at LCgs levels, oviposition was completely inhibited. Thus, a progeny emergence was completely suppressed at LC9s levels as well as at LC50 of acetone extract. Chloroform extract indicated a stow rate of degradation after 1 month of storage (90% mortality). All tested plant extracts caused loss in grain wheat after 45 days of storage, but chloroform extract was the most effective compound. Most treatments didn't affect water absorption but viability was significantly reduced. Petroleum ether and chloroform extracts caused a significant inhibition effect of AchE in adult insects while acetone extract caused a significant activation effect. All extracts caused Significant activation effects on AcP and AlkP except chloroform and acetone extracts treatments that caused a significant inhibition effect on AcP in adults. Moreover, all extracts showed Significant decrease in protein and carbohydrate contents of adult insects, except carbohydrate content of adults treated with acetone extract, meanwhile, there was a significant increase of lipid content in adults treated with all extracts and carbohydrate content in adults treated with acetone extract. | ||||
