中文摘要：
【目的】 为了研究添加增效助剂对新型杀虫剂防控棉蚜Aphis gossypii 田间效果的影响，明确其减施增效作用。【方法】 采用叶片浸渍法测定了增效剂和新型杀虫剂混用对棉蚜室内生物活性的影响，测定了表面张力、接触角、持留量等指标，分析增效剂对药剂物理性状的影响，并采用茎叶喷雾法进行田间药效验证。【结果】 室内试验表明，6种增效剂分别与4种杀虫剂混配均表现一定的增效作用，对氟吡呋喃酮、溴虫氟苯双酰胺、三氟苯嘧啶和双丙环虫酯的增效比分别为6.35-274.36、3.00-26.40、2.69-17.57和1.01-11.37。物理性状研究表明，6种增效剂分别降低了药液在棉花叶片1.76%-38.56%表面张力及0.16%-15.79%接触角；不同增效剂对药剂在叶片表面持留量影响存在差异。田间试验结果显示，中保云纹清与双丙环虫酯混配防效和持久性最佳，药后14 d防效高达99.68%；青皮桔油、中保云纹青和金诺对三氟苯嘧啶药后7 d防效提升29.18%-69.01%；橙皮精油和中保云纹青对溴虫氟苯双酰胺防效分别提升32.57%-47.69%和35.20%-47.40%；青皮桔油、中保云纹青和乐透可提升氟吡呋喃酮防效1.62%-12.86%。【结论】 50 g/L双丙环虫酯可分散液剂（减量30%）与中保云纹青混用对棉蚜防治效果最佳，17%氟吡呋喃酮可溶性液剂（减量30%）与乐透混用次之，研究结果为棉蚜绿色防控及药剂科学施用提供了理论依据和技术参考。
英文摘要：
[Aim] To determine the benefits of adding synergists to four
novel insecticides to control Aphis gossypii; specifically, to clarify
if these reduce the amount of insecticide used and improve the effectiveness of
control. [Methods] The
leaf-dip method was used to evaluate the effects of synergists on the toxicity
of novel insecticides to A. gossypii. Surface tension, contact angle,
and retention, were measured to analyze the effects of synergists on the
physicochemical properties of each insecticide. Field efficacy was further
evaluated using the stem-leaf spray method. [Results] All six synergists showed varying degrees
of synergy with the four insecticides tested. Synergistic ratios ranged from
6.35-274.36 for flupyradifurone, 3.00-26.40 for broflanilide, 2.69-17.57 for
triflumezopyrim, and 1.01-11.37 for afidopyropen. Physicochemical analyses
revealed reductions in surface tension (1.76%-38.56%) and contact angle (0.16%-15.79%),
with synergists differing in their effects on solution retention. Field trials
confirmed significant improvements: The combination of Zhongbao Yunwenqing and
afidopyropen had the best efficacy and persistence, with a control rate of up
to 99.68% after 14 days. Green tangerine peel oil, Zhongbao Yunwenqing, and
Jinnuo improved the effectiveness of spraying triflumezopyrim by 29.18%-69.01%.
Green tangerine peel oil and Zhongbao Yunwenqing improved the effectiveness of
broflanilide by 32.57%-47.69% and 35.20-47.40%, respectively. Green tangerine
peel oil, Zhongbao Yunwenqing, and Letou improved the effectiveness of
flupyradifurone by 1.62%-12.86%. [Conclusion] The combination of 50 g/L afidopyropen DC
(reduced by 30%) with Zhongbao Yunwenqing was the best in terms of control, followed by 17% flupyradifurone SL
(reduced by 30%) and Letou. These results offer a theoretical basis
and practical guidance for the environmentally friendly, and rational, use of
insecticides to control of A. gossypii.
