studies on the insecticidal effect of spinosad on the adults of tribolium castaneum (herbst), sitophilus oryzae(l.) and oryzaephilus surinamensis(l.) under laboratory conditions
abstract due to economical importance of stored product pests and resistance to conventional insecticides, it is necessary to use novel and suitable compounds in control programs. therefore, we evaluated the toxicity of spinosad to three important storage insect, red flour beetle, tribolium castaneum (herbst), rice weevil, sitophilus oryzae (l.), sawtoothed grain beetle oryzaephilus surinamensi...
