在实验室条件下,采用光触媒聚乙烯薄膜对常见储粮害虫米象、谷蠹、赤拟谷盗和绿豆象的杀灭 效果、驱避效果和子代抑制效果进行了研究。结果表明:光触媒聚乙烯薄膜对供试的几种害虫的成虫有显著的 驱避效果,驱避率为米象60.9%～75.1%,谷蠹25.8%～77.8%,赤拟谷盗78.0%～84.6%,绿豆象35.7%～ 37.5%;对绿豆象的子代抑制效果显著,其平均抑制率为80.9%。光触媒聚乙烯薄膜对供试成虫的致死效果 不显著。
Under laboratory conditions, the photocatalytic polyethylene film was used to study the killing effect, repellent effect and offspring inhibitory effect on common grain pests such as rice moth, rice borer, red tarragon and mung bean. The results showed that photocatalyst polyethylene film had significant repellent effect on the adult pests of several pests tested. The repellent rates were 60.9% -75.1% for rice, 25.8% -77.8% for rice gourd, 78.0% 84.6% and mung bean as 35.7% -37.5%, respectively. The inhibitory effect on mung bean progeny was significant, with the average inhibition rate of 80.9%. Photocatalyst polyethylene film on the lethal effect of test adults was not significant.
