| Abstract | ||
| This study was carried out to show the effect of pyrithroid pesticides Flash ( Alphasypermethrin ) , Sibex (Deltamethrin) and insect growth regulators Match , Dimilin and biological factor as Beauveria bassiani on Khapra beetle Trogoderma granarium (Everts) . The results showed the effect of pesticides , fungus on egg hatching of the insect it appeared that Flash brings down the egg hatch to 6.7% While Sibex to 28.3% . the fungus B. bassiana brings down it to 35% at 2x1010 spore/ml while it gave56.67% at2× 106 spore/ml. Flash gave 95.56, 67.46, 57.98 and 36.46% death percentage respectively at 1, 2, 3 and 4 larvae stages, while Dimilin gave 41.46 , 22.90 , 10.68 and 5 % death percentage respectively at the same larvae stages . The fungus B. bassiana gave 69.11, 45.38, 38.66 and 30.63 % death percentage respectively at the same larvae stage when using 2x1010 spore/ml. As for adult, the maximum death rate occurs in Flash 84.54 % but the minimum death rate occurs in Dimilin 67.79 %. The use of suspension of fungus maximum death rate48.68% at 2×1010 sport/ml and spore/ml decrease to25.71% at 2×106 sport/ml. The insecticide Flash inhibited the B. bassiana growth to 24.57 % in the vitro . Match gave a maximum growth inhibition of fungus which reached 56.25 % . | ||
