中文摘要:

采用叶管药膜法（TIBS）室内测定了2014-2015年海南主要豇豆种植区三亚、澄迈和海口豆大蓟马田间种群对6种常用杀虫剂敏感性的年度变化。结果表明，2014年，三亚种群对甲维盐、高效氯氰菊酯和吡虫啉产生了低水平抗性，抗性倍数分别为5.39、8.07和5.44倍，澄迈种群对甲维盐也产生了5.93倍的低水平抗性，海口种群对药剂仍处于敏感阶段；2015年，三亚种群对甲维盐、乙基多杀菌素、吡虫啉和啶虫脒产生了低水平抗性，抗性倍数分别为7.97、5.43、7.51和5.44倍，对高效氯氰菊酯产生了中等水平抗性，抗性倍数为12.99倍；澄迈种群和海口种群对除甲维盐外的其它药剂仍处于敏感状态，但年度间相比，均表现出药剂敏感性下降，有进一步产生低水平抗性的趋势。海南各监测地区均未发现豆大蓟马对阿维菌素产生抗性，可以考虑其它药剂与阿维菌素轮换使用。

英文摘要:

Resistance to 6 common used insecticides in field populations of Megalurothrips usitatus from Sanya, Chengmai and Haikou city of Hainan Province was monitored by a modified TIBS method in 2014 and 2015. The results showed that M. usitatus populations in Sanya city exhibited low levels of resistance to emamectin benzoate, β-cypermethrin and imidacloprid (5.39, 8.07 and 5.44 folds, respectively), and the population of Chengmai city was also exhibited low levels of resistance to emamectin benzoate (5.93 folds), the other populations in Hainan area were still relatively sensitive to tested insecticides. By 2015, Sanya population had developed low levels of resistance to spinetoram and acetamiprid, besides emamectin benzoate, and imidacloprid in 2014, and also had developed moderate levels of resistance to β-cypermethrin (12.99 folds). The Chengmai and Haikou populations were still sensitive to other insecticides tested, except had developed low levels of resistance to emamectin benzoate (5.43 and5.69 folds, respectively). But compared with the insecticide resistance in 2014, the populations of Sanya, Chengmai and Haikou all had decreased susceptibility to 6 tested insecticides. All field populations tested displayed no resistance to abamectin (<3 folds).
