摘　　要：按不同质量比向高密度聚乙烯中加入溴氰菊酯和增效醚后制成薄膜,研究6种新型包装材料对8种储粮害虫成虫在2种穿透方式下的防虫效果,明确不同包装材料对常见储粮害虫的防虫能力。结果发现:含有药剂的新型包装材料的防虫效果均优于未添加药剂的包装材料。相比于空白薄膜,害虫对含有药剂薄膜的穿透率极低。含有0.5 g/kg溴氰菊酯的薄膜和含有1.5 g/kg溴氰菊酯、0.6 g/kg增效醚的薄膜无法被试虫穿透。随着处理时间的延长,试虫在含有药剂的薄膜上存活率下降,最低可降至0。相比于其他薄膜,含有1.5 g/kg溴氰菊酯、0.6 g/kg增效醚的薄膜表现出较佳的防虫效果。By adding deltamethrin and synergist ether to high-density polyethylene in different mass ratios,a thin film was made to study the pest control effects of six new packaging materials on eight types of stored grain pests under two penetration modes,and to clarify the pest control ability of different packaging materials on common stored grain pests.The results showed that the insect control effect of new packaging materials containing pesticides was better than that of packaging materials without added pesticides.Compared with blank films,the penetration rate of pests through films containing pesticides was extremely low.Films containing 0.5 g/kg deltamethrin and films containing 1.5 g/kg deltamethrin and 0.6 g/kg synergist could not be penetrated by the test pests.As the processing time prolonged,the survival rate of test pests on the film containing the drug decreased,and the lowest could be reduced to 0.Compared with other films,films containing 1.5 g/kg deltamethrin and 0.6 g/kg synergist ether exhibited better application pest prevention effects.
