Abstract
The wheat and barley are the most important stored products and the agricultural stored product pests are the most important insects for this product. The resistance of insects, especially stored products pests to chemical poisons such as phosphin and malathion caused a lot of research about natural, physiological, biological and microbial control. Azadirachta indica Adr. Juss. and Eucalyptus camaldulensis Dehnh. are important trees used for non-chemical control. In this study, the insecticide and repellent property ofneem leaf powder and Eucalyptus seed and leaf powder on Trogoderma granarium and Tribolium sp.were accomplished. Results for insecticide property at 8 treatments and 4 replications showed that LC50 for neem leaf powder on Trogoderma granarium was 5.4, on Tribolium sp.was 5.33gr/100gr. Eucalyptus seed powder on Trogoderma granarium was 5.98 and on Tribolium sp.5.63gr/100gr, LC50 for Eucalyptus leaf powder on Trogoderma granarium 6.86, on Tribolium sp.6.35gr/100gr. The results for repellent property at 4 treatments and 4 replications showed that the repellent property of neem leaf powder on Trogoderma granarium was 80% and on Tribolium sp. was 86.7%. The repellent property of Eucalyptus seed powder on Trogoderma granarium was 67%, Eucalyptus leaf powder was 50%, repellent property of Eucalyptus seed powder on Tribolium sp. 75% and Eucalyptus leaf powder 65%.
