Abstract

Three concentrations (0.5, 1, 2) mg/ ml of hot water extract, alcoholic extract, and phenolic extract of Quercus spp. were used as biocontrol of Tribolium castaneum adult by Putting 10 grains of clean rice in a petri dish with five adults and sprayed with the previous concentrations of the extracts for three replicates, as well as the control treatment (sprayed with solvent without the plant extract). The results indicated that the alcoholic extract was significantly superior to the aqueous and phenolic extracts. The alcoholic extract caused 100% death after 16 hours of exposure at a concentration 2 mg/ ml, and the aqueous extract caused 100% mortality after 48 hours at a dosage 2 mg/ ml, while the phenolic extract caused 50% mortality after 16 hours at a concentration 2 mg/ ml.
