| 为了明确新烟碱类杀虫剂亚致死剂量对麦长管蚜和棉蚜拒食作用的差异, 通过铷标记法、蜜露法以及两种蚜虫体内总糖、总脂含量的测定研究了新烟碱类杀虫剂亚致死剂量对麦长管蚜和棉蚜取食的影响。结果表明, 铷标记法和蜜露法测定的新烟碱类杀虫剂亚致死剂量对麦长管蚜的拒食率均在80%以上, 而对棉蚜的拒食率均在25%以下。蚜虫体内总糖总脂含量测定结果表明, 新烟碱类杀虫剂亚致死剂量处理后麦长管蚜体内总糖、总脂含量均显著低于对照, 而棉蚜体内总糖、总脂含量与对照均无显著差异。三种方法测定结果一致表明新烟碱类杀虫剂亚致死剂量对麦长管蚜具有很强的拒食作用, 而对棉蚜没有明显的拒食作用。 |
| 英文摘要: |
| The differences in the effects of sublethal dose of neonicotinoid insecticides on the feeding behavior of Sitobion miscanthi and Aphis gossypii were studied by using marking method with trace element Rb, honeydew method and determination of the changes in the contents of total sugars and total lipids of aphids. The results of Rb marking method and honeydew method showed that the antifeedant rates of sublethal dose of neonicotinoids against S.miscanthi were all above 80%. However, the antifeedant rates of sublethal dose of neonicotinoids against A. gossypii were all below 25%. The contents of total sugars and lipids in S.miscanthi were significantly lower in neonicotinoids-treated aphids than in the control, while there was no significant difference between treated A. gossypii and the control. These results indicated that the sublethal dose of neonicotinoids had a significant antifeedant effect on S.miscanthi, but there was no obvious antifeedant effect on A. gossypii. |
