摘要： 为减轻豇豆白粉虱的发生，减少化学农药用量、残留和环境污染，采用测报调查、随机区组设计和统计分析等方法，开展了化学农药呋虫胺、啶虫脒和吡蚜酮，生物农药阿维菌素防治豇豆温室白粉虱农药田间药效试验。结果表明：在温室大棚秋季豇豆白粉虱发生较重情况下，每公顷用1.8%阿维菌素EC 375 g、20%呋虫胺SP（护瑞）600 g、5%啶虫脒WP 600 g、25%吡蚜酮WP 600 g（对照药剂），5~8天施药1次，连续施用3次，药后7、14、20天，防治效果分别达90.9%、97.0%、88.0%、93.9%，97.4%、92.1%、84.2%、89.4%和95.6%、86.7%、82.2%、84.5%，且药后7天呋虫胺与阿维菌素和吡蚜酮，极显著高于啶虫脒，阿维菌素与啶虫脒和吡蚜酮之间差异不显著；药后14天，阿维菌素与呋虫胺和吡蚜酮差异不显著，极显著高于啶虫脒，呋虫胺与吡蚜酮差异不显著，显著高于啶虫脒；药后20天，阿维菌素极显著高于呋虫胺、啶虫脒和吡蚜酮，呋虫胺与啶虫脒和吡蚜酮差异不显著。同时，生物农药阿维菌素在药后7天，防效稍低于化学农药呋虫胺，药后14天，防效高于呋虫胺，药后20天，防效极显著高于呋虫胺。这4种药剂尤其是生物农药阿维菌素不仅可以作为防治温室白粉虱的理想药剂，而且可以作为现代农业示范区、无公害农产品、绿色农产品和有机农产品的理想药剂。

Abstract: In order to mitigate the occurrence and damage of cowpea whitefly, reduce chemical pesticide consumption, residue and environmental pollution, the methods of forecasting, randomized block design and statistical analysis were used in field efficacy trials, to study the control effect of cowpea anthracnose by using chemical pesticides dinotefuran, acetamiprid, pymetrozine, and bio-pesticide avermectin. The results showed that after applying 1.85% avermectin EC 375 g, 20% dinotefuran SP 600 g, 5% acetamiprid WP 600 g, and 25% pymetrozine WP 600 g (control pesticide) per hm2 once every 5-8 days, and 3 times continuously under serious autumn occurrence of greenhouse whitefly, the control efficacy was 90.9%, 97.0%, 88.0%, 93.9% respectively on the 7th day after the pesticides application; 97.4%, 92.1%, 84.2%, 89.4% respectively on the 14th day after the pesticides application; and 95.6%, 86.7%, 82.2%, 84.5%, respectively on the 20th day after the pesticides application. The control effects among avermectin, acetamiprid and pymetrozine were not significantly different, while the effects of avermectin and pymetrozine were significantly higher than that of acetamiprid on the 7th day. The control effects among avermectin, dinotefuran and pymetrozine were not significantly different, while significantly higher than that of acetamiprid on the 14th day. The control effect of avermectin was significantly higher than that of dinotefuran, acetamiprid and pymetrozine on the 20th day. Meanwhile, the control effect of avermectin was slightly lower, higher and much higher than that of dinotefuran on the 7th, 14th, 20th day respectively after the treatment. These results indicated that the four pesticides, especially bio-pesticide avermectin, were ideal pesticides, which could not only be used for controlling cowpea whitefly, but also realize modern, green, organic and ecological agricultural production.
