In order to clarify the controlling effect of different packaging materials on common storage pests, the penetration and survival of 7 kinds of high density polyethylene films with different concentrations of deltamethrin by the larvae of 3 common species of stored grain pests (Tribolium castaneum (Herbst), Tribolium confusum Duval and Lasioderma serricorne (Fabricius)) were investigated after being treated by two penetration methods for different times at 27~29 ℃ and 70%~80% RH. The results showed that all the tested new insect-proof films had certain insect resistance capabilities, which were different based on species of stored grain insects. In addition, the insect resistance capability of the 6 kinds of new films containing chemicals was higher than that of the control films after 9 days of treatment, and the anti-penetration rate of 1% A (HDPE particle containing 5% deltamethrin by mass) film, 3% A film, 1% B (HDPE particle containing 5% deltamethrin and 2% isoethers by mass) film and 3% B film was 100% under two penetration modes. The survival rate of all three species larvae decreased with increasing treatment time. After 9 days of parallel penetration treatment, the survival rate of three species of larvae on 3%B film was significantly lower than that of other films, and the survival rate of L. serricorne larvae reduced to 10% at the lowest. According to the penetration resistance and larvae survival rate of the test insects on the films, 3% B film had the best insect control effectiveness.
