The results of food kind exposed to radiation exhibited a different mean mortality on adults reached 52.41 ,58.70 ,50.37 and 52.41% and for percent egg hatch reached 12.96 ,17.78 ,18.33 and 18.33% while the mean mortality in larvae reached 45.56 ,46.48 ,41.30 and 38.15%, and the percentage of pupae transformation to adults reached 47.96 , 46.80 , 45 ,43.52%.Results were positively proportion with increasing the energy levels reached 22.08 , 64.86 , 65.14% for larvae , while the mean percentage of eggs hatchling and the means percentages of pupae transformation to adults decrease with increasing energy levels reached 23.61 , 17.66 and 10.28% for egg hatching , and 58.61 , 40.31 and 29.17% for pupae transformation .The means of adults and larvae mortality increase with increasing the exposure period to radiation reached 31.39 , 58.06 , 72.78 , 75.83 and 76.94% , and 21.67 ,41.39 ,54.72 ,64.44 and 74.17% respectively. Means of eggs hatching percentage and pupae transferred to adults were proportionally decrease with increasing the exposure period. Also the storage of bags affected on mortality of adults Khapra beetle , which reached in bags 5.83%. Compared without bags reached zero, and the mean percentage of eggs hatching in bags treatment decrease reached 31.67% compared without bags reached 100%. While it was no differences in the larvae mortalities of both treatments . Also the pupae transferred to adults were proportionally decrease in bags treatment reached 89.17% compared in controlling without bags reached 100%.

The effect of Hot air on the Killing a percentage of different stages of Red flour beetle Tribolium castaneum and The Khapra beetle Trogoderma granarium , have study: the larval stage of Khapra beetle is more resisting in expansion to Hot air in killing 50 a percentage having 104°C and in killing 95 % is in 110°C , in Red flour beetle the killed 50 % in all the stages of the same (82°C) but in the killing 95% the pupal stage is more resisting to arrive at 92°C and nearby in adult stage (90°C).

The results indicated that the kinds of legume seeds and storage period affect to the activity of khapra beetle which represented in the population density of the insects and loss weight of infested seeds and growth rate of insect. The results indicated that the chick pea, Caw pea and green gram had more preferred for insect feeding than another legume seeds as lentil, broad bean, pea and bean, and had a high general mean for insect numbers was 245.67 insect for chick pea and followed caw pea seeds 188.00 insect and green gram seeds 140.89 insect. The general mean of insect numbers were increased with increasing storage period which were 26.05, 72.57 and 171.57 insect for storage period of 3, 6 and 9 moths respectively. According to other characteristics as loss weight, loss percentage of weight and growth rate were higher on the chick pea from another kinds. These characters that arranged between zero on the broad bean seeds and 15.67 gm., 62.68 % and 3.51 individual / month of the chick pea seeds.

The results of studying the effect of the type of host food by which the larvae were reared on , and the type of oil used for some vegetable oils ( sunflower ,Sesame ,Peanut , Soybean and Almond ) on the 3rd instar of grain beetle , showed a different mortality percentage and the Peanut oil exhibit a superior , killing percentage reached 72.5 . and toxicity index 100 on insect larvae reared on Peanut in comparisor with 49.3 % and 41.3 for toxicity index . The lowest killing percentage 43.7 % was obtains from treating larvae reared on Sunflower with Sunflower oil in comparison with 66.6% on larvae reared on wheat .

Study results showed the effect of some vegetable oils and host food in the proportion of activation, synergy and potentiation of pesticide Alpha-Cypermtherin grain beetle larvae , Atfouk mixture peanut oil by mixing 3 Oil: 1 pesticide toxicity to the revitalization of the pesticide in the grain beetle larvae of the third instar of poetry at a rate of 1.62, which was the rate of activation synergistically 1.57 , The sesame oil gave a mixture with the insecticide Alpha-Cypermtherin by mixing oil 2: 1 ratio less insecticide antagonism reached 0.15 .

Result of attractant and repellent effect at three concentration 1 ,3 and 5 % of water and hexen cumin and Fennel seeds extracts on Khabra larvae feeding on wheat seeds, showed that both extract types had repellent effect at all concentrations in use ,the higher repellent effect was 90 % and balanced power ratio was -251 , when cumin Fennel water extracts were used at 5% ,While the lower repellent effect was 30% and balanced power ratio was –58.33.when Fennel water extract was used at 3%. The general effect of cumin in repellent power effect was higher than Fennel repellent power effect with an average -142.45 , -112.67 respectively , the result also showed that cumin hexan extract caused the higher repellent power effect -146 while Fennel hexan extract scored the lower repellent power effect -111.23 .

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.
