8种杀虫剂对苹果树绣线菊蚜的田间防效评价

对8种不同作用机理杀虫剂防治苹果树绣线菊蚜的效果进行了田间试验。结果表明:马拉硫磷、啶虫脒、高效氯氰菊酯、高效氯氟氰菊酯、噻虫嗪、吡虫啉、硫丹、阿维菌素均是防治苹果绣线菊蚜的有效药剂。啶虫脒和吡虫啉为防治苹果绣线菊蚜的首选药剂。噻虫嗪、马拉硫磷、硫丹可作为专用杀蚜剂。阿维菌素、高效氯氰菊酯、高效氯氟氰菊酯可作为防治绣线菊蚜的兼治药剂,一般不推荐为专用杀蚜剂。

Evaluation of eight insecticides against Aphis citricola

Field trials were conducted to validate the efficacy of different insecticides in controlling Aphis citrico-la. The results indicated that all of the 8 insecticides, including carbofos, acetamiprid, beta-cypermethrin, lamb-da-cyhalothrin, thiamethoxam, imidacloprid, endosulfan and abamectin, were effective. Acetamiprid and imida-cloprid were the best choices for controlling Aphis citricola. Thiamethoxam, endosulfan and carbofos could also be used as exclusive agents. Abamectin, beta-cypermethrin and lambda-cyhalothrin should be used as accessory agents, but not as exclusive agents.
