%X <span style=\"font-size:14px;\">目的：明确新乡地区麦蚜对3种常用杀虫剂的抗性现状，指导本地区田间蚜虫防治实践。方法：采用药膜法室内测定新乡3县麦蚜对吡虫啉、氧乐果、高效氯氰菊酯三种常用杀虫剂的抗药性。并对辉县市小麦蚜虫的抗药性进行了大田药效试验。结果：室内试验表明；三县麦长管蚜对氧乐果抗性均处敏感水平，辉县和原阳麦长管蚜对吡虫啉均有较明显的抗性，其中在原阳达到中等水平抗性。原阳麦长管蚜对高效氯氰菊酯抗性为低水平抗性，其他两地处敏感水平。大田实验表明：辉县市麦蚜防治要达到理想防效(90%)，吡虫啉、高效氯氰菊酯、氧化乐果至少需用到推荐用量的2.59倍、1.10倍和1.57倍。结论：辉县市、卫辉市和原阳县麦田的麦长管蚜均对吡虫啉、高效氯氰菊酯、氧乐果产生抗性程度差异较大，但并未达到高水平抗性。原阳县应限制使用吡虫啉，以减缓抗性发展。</span><br />
<span style=\"font-size:14px;\">Objective: In order to clarify the resistance status of wheat aphid to three common insecticides in Xinxiang distrct and guide prevention practice of the field aphid in this district. Methods: Apply the drug film method to determine the resistance of wheat aphid to three common insecticides im-idacloprid, Omethoate and beta cypermethrin in Xinxiang 3 districts and carry out the field efficacy test of wheat aphid resistance in Huixian. Results: Laboratory tests show that the resistance of wheat long tube aphid to Omethoate in three contries is sensitive, the resistance of wheat long tube aphid to imidacloprid in Huixian and Yuanyang is obvious, and it reaches a medium level in Yuanyang. The resistance of wheat long tube aphid to beta cypermethrin in Yuanyang is low, and it is sensitive in another two places. The field experiment shows that it is necessary to apply at least 2.59 times, 1.10 times and 1.57 times of the recommended dosage of imidacloprid, beta cypermethrin and Omethoate so as to achieve the ideal control effect (90%). Conclusion: The resistance of wheat aphid to imidacloprid, beta cypermethrin and Omethoate varies greatly in Huixian, Weihui and Yuanyang wheat fields, but there is no population with high resistance. The application of im-idacloprid should be restricted in Yuanyang for the sake of slowing down the development of resistance.</span>
