摘要: 【目的】 分析棉蚜对传统烟碱类杀虫剂吡虫啉、啶虫脒、噻虫嗪的敏感性,研究青皮桔柚、有机硅、激健3种增效剂对棉蚜的增效作用。【方法】 采用浸叶法测,定3种增效剂与3种烟碱类杀虫剂混配后对棉蚜的生物活性及增效作用。【结果】 吡虫啉、啶虫脒、噻虫嗪对棉蚜24 h LC50分别为11.878、24.452、12.110 μg/mL,吡虫啉和噻虫嗪相对毒力分别是啶虫脒的2.059和2.019倍。添加3种增效剂后,9种农药+增效剂组合对棉蚜的毒力均有显著提高,其中吡虫啉+青皮桔油、啶虫脒+有机硅、噻虫嗪+青皮桔油的组合增效作用最佳,对棉蚜24 h LC50分别为0.328、1.987、0.704 μg/mL,增效比分别为36.213、12.306、17.202。【结论】 青皮桔柚、有机硅、激健3种增效剂在新疆棉区棉蚜绿色防控和农药减施增效技术可应用。

Abstract: 【Objective】 This study aims to study the sensitivity of Aphis gossypii to traditional nicotine insecticides imidacloprid, acetamiprid and thiothiazide and clarify and synergistic effects of the three synergists: green peel orange oil (GPOO), organosilicon (OSi) and Jijian adjuvant. (JJ, active ingredients: corn germ oil, rapeseed oil and soybean oil, etc.) mixed with imidacloprid, acetamiprid and thiamethoxam on Aphis gossypii.【Method】 The bioactivity and synergistic effect of three synergists mixed with three nicotine insecticides on Aphis gossypii were determined by leaf soaking method. 【Result】 After 24 hours of treatment, the LC50 of imidacloprid, acetamiprid and thiamethoxam to Aphis gossypii were 11.878, 24.452 and 12.110 μg/mL, respectively. The relative toxicities of imidacloprid and thiamethoxam were 2.059 and 2.019 times higher than those of acetamiprid, respectively. After adding three synergists, the bioassay of nine combinations of pesticide+synergist to Aphis gossypii was significantly increased. Among them, imidacloprid+GPOO, acetamiprid+OSi, thiamethoxam+GPOO had the best synergistic effect. After 24 hours of treatment, the LC50 were 0.328, 1.987, 0.704 μg/mL, and the synergistic ratio was 36.213, 12.306 and 17.202, respectively. 【Conclusion】 Green peel orange oil, organosilicon and Jijian adjuvant have good potential in the application of green control and pesticide reduction and synergism technology for cotton Aphis gossypii in Xinjiang.
