| Abstract | ||
| A series of experiments were carried out to study the effects of powders and aqueous extract of plants Matricaria chamomilla L. , Eucalyptus camaldulensis (Dehn.) , Allium sativum L. , Allium cepa L. and Achillea micrantha M.B., at four concentrations , 1,2,4 and 6 % as wheat grains treatment against the khapra beetle Trogoderma granarium Everts . Powders of plants showed repellent effect to the larvae when used free choice test for feeding , it was found negative values for repellent especially at 6% concentration. The aqueous extracts , also , shows repellent effect but lower than effect of powders . Rearing of T. granarium on wheat grains treated with the A. micrantha , A. sativum , A. cepa and E. camaldulensis at 6% concentration effect the biology of the insects ,the adults gave a progeny of 12,15,16 and 20 individuals at powders and 17 , 20 , 23 ,and 24 individuals at extracts from one pair of insects , respectively , incomparison to 40 individuals in the control treatment. | ||
