【目的】为了明确绿盲蝽Apolygus lucorum不同地理种群对化学杀虫剂的抗性现状及发展趋势,并为制定有效的化学防治措施及抗性治理策略提供参考,【方法】本文采用玻璃瓶药膜法,连续4年监测了采自黄河流域、长江流域棉区绿盲蝽田间种群对高效氯氰菊酯和毒死蜱的抗性水平及变化动态。【结果】(1)与室内饲养的廊坊敏感品系(Susceptible strain from Langfang,SLF)相比,长江流域棉区江苏南京及安徽滁州种群对2种药剂均未产生明显抗性(<5倍),江苏盐城种群对高效氯氰菊酯(3.4~8.5倍)和毒死蜱(3.3~5.8倍)仅有低水平抗性;(2)黄河流域棉区河南安阳、山东滨州及河北沧州种群对高效氯氰菊酯(7.1~22倍)、毒死蜱(5.2~20倍)均产生了中低水平抗性。【结论】2011至2014年间,各地理种群对两种药剂的敏感性在不同年度之间变异幅度小于3倍,抗性发展比较缓慢。黄河流域、长江流域棉区绿盲蝽田间种群对上述2种药剂敏感性的差异可能与当地用药历史和用药量有关。
【Objective】 In order to clarify the status quo and development trend of Apolygus lucorum resistant to chemical insecticides, and to provide reference for establishing effective chemical control measures and resistance control strategies, 【Methods】 In this paper, Membrane method, for 4 consecutive years to monitor the population from the Yellow River, the Yangtze River valley cotton field Obsidian populations of beta-cypermethrin and chlorpyrifos resistance levels and dynamic changes. 【Result】 (1) Compared with susceptible strain of Langfang (SLF), Nanjing, Jiangsu Province and Chuzhou, Anhui Province in the Yangtze River Basin did not show significant resistance (<5-fold) The population of Yancheng in Jiangsu Province had only low level of resistance to beta-cypermethrin (3.4 ~ 8.5 times) and chlorpyrifos (3.3 ~ 5.8 times); (2) The population of beta- Times), chlorpyrifos (5.2 ~ 20 times) have produced low-level resistance. 【Conclusion】 From 2011 to 2014, the sensitivity of each geographical population to the two agents varied by less than 3 times in different years and the resistance developed more slowly. The difference of sensitivity between the two populations in the Yellow River and Yangtze River cotton fields may be related to the history of local drug use and dosage.
