摘要
为明确不同包装材料对常见储粮害虫的防虫效果,在27~29℃、70%~80%RH条件下,研究了经平行和垂直两种穿透方式处理不同时间后,3种储粮幼害虫(赤拟谷盗、杂拟谷盗、烟草甲)对7种有不同浓度溴氰菊酯的高密度聚乙烯薄膜的钻蛀情况和试虫存活情况。研究结果表明,参试薄膜都有一定的防虫能力,但对不同种类害虫的防虫能力不同。处理9 d后,6种含有药剂的新型薄膜的防虫能力均高于空白对照薄膜,其中1%A(含质量分数5%溴氰菊酯的高密度聚乙烯颗粒)薄膜、3%A薄膜、1%B(含质量分数5%溴氰菊酯和质量分数2%的增效醚的高密度聚乙烯颗粒)薄膜和3%B薄膜在两种穿透方式下对3种试虫的抗穿透率均为100%。3种幼虫的存活率均随处理时间延长而降低。平行穿透处理9 d后,3%B薄膜上3种试虫的存活率显著低于其他薄膜,其中烟草甲幼虫存活率最低可降至10%。从总体来看,3%B薄膜的防虫效果最佳。
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.
