| Abstract | ||
| Anise ( Pimpinella anisum) and Fennel (Foeniculum vulgare) oils are used to protect stored cereals from infestation with The rice weevil (Sitophilus oryzae) and larvae of The Mediterranean flour moth (Ephestia kuehniella) by treating packaging material (polyethelene) with two different thickness with five different concentrations(100,75,50,25 and 12.5%) using acetone and chloroform as solvents. The results showed that in all treatments the percent mortality increased by increasing concentration and time of exposure to oils from 24 to 48 and 72 hours and in most cases the Lc50 of the rice weevils exceeds that of The Mediterranean flour moth larvae and the lethal effect of fennel oil is more than that of Anise oil and chloroform is effective as solvent than acetone | ||
