Abstract: In this study, the contact toxicity of 12 kinds of PE insect-resistant film provided by Tianjin university of science and technology against Tribolium castaneum, the main stored-grain pests, were evaluated under the conditions of 25℃, relative humidity of 70%. All of the tested insect-resistant film showed favorable contact toxicity against Tribolium castaneum. The contact toxicity rate of the combination of tetramethrin, capsaicin and malathion （1-2 and 1-3） and the combination of ＂Baoliang＇an＂, capsaicin and carbarvl in 70 h were all 70%, and they were 90% in 80 h.
