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
