为适应新形势下粮食行业“绿色”、“环保”的发展方向,研究了八种植物提取物对赤拟谷盗、米象两种主要储粮害虫的触杀作用及驱避作用效果。研究结果表明,相较于其他几种植物提取物,柑橘精油对两种虫种均有较强的触杀和驱避作用。柑橘精油在使用量约为1.05μg/cm 2的剂量处理72 h后,对赤拟谷盗成虫驱避率能达到Ⅳ级以上且触杀校正死亡率接近100%,柑橘精油在使用量约为2.10μg/cm^( 2)的剂量处理72 h后,对米象成虫驱避率能达到Ⅲ级以上且触杀校正死亡率达到70%以上。

In order to adapt to the development direction of“green”and“environmental protection”in the grain industry under the new situation,the contact activity and repellent activity of eight plant extracts on red flour beetles and rice weevils were studied.The results showed that citrus essential oil had a strong contact and repellent effect on both insect species.After 72 hours of treatment with citrus essential oil at a dose of about 1.05 μg/cm~2,the repelling rate of red flour beetles could reach grade Ⅳ and above and the corrected mortality ...
