摘　　要：【目的】本文全面评估了香蕉黄胸蓟马Thrips hawaiiensis田间种群对杀虫剂的抗性水平,旨在为更科学合理地防治该虫提供依据。【方法】室内采用叶管药膜法(TIBS),分别在2013、2015年监测了昌江、澄迈、临高、东方4个地区香蕉黄胸蓟马田间种群对10种杀虫剂的抗性水平。【结果】从2013—2015年,总体上海南香蕉黄胸蓟马田间种群对大多数杀虫剂的敏感性均有不同程度的下降,但仍处于敏感状态。其中,香蕉黄胸蓟马田间种群对传统药剂甲维盐、毒死蜱和高效氯氰菊酯,及新型杀虫剂乙基多杀菌素、溴氰虫酰胺和螺虫乙酯均保持较敏感状态(抗性倍数<5)。但监测的所有田间种群(昌江、澄迈、临高、东方)均对啶虫脒均已产生了中等水平抗性(抗性倍数分别为15.19、11.19、17.46、13.58倍);对阿维菌素均产生了低水平抗性(抗性倍数分别为9.06、8.95、13.35、6.57倍);另外,东方种群对多杀菌素、吡虫啉,以及临高种群对吡虫啉均产生了低水平抗性(抗性倍数分别为7.11、7.48、8.28倍)。【结论】因此,建议在香蕉同一生长季节应避免重复使用或限用啶虫脒和阿维菌素,应注意与其它药剂的混用、轮用,以延缓香蕉黄胸蓟马抗药性的发展。[Objectives] To evaluate current levels of insecticide resistance in Thrips hawaiiensis, and provide information to improve the management of this pest. [Methods] The resistance of T. hawaiiensis collected from four populations on Hainain; Changjiang, Chengmai, Lingao and Dongfang, to ten insecticides was tested using the leaf-tube residual bioassay（TIBS） from 2013 to 2015. [Results] Although decreased susceptibility was observed in all four populations from 2013 to 2015, all four were still relatively sensitive to the most insecticides tested. All populations were sensitive to traditional insecticides, including emamectin-benzoate, chlorpyrifos and betacy permethrin, and novel insecticides such as spinetoram, cyantraniliprole, and spirotetramat（resistance ratios5）. However, all four populations developed moderate resistance（resistance ratios of 15.19, 11.19, 17.46, 13.58 fold, respectively） to acetamiprid compared to a susceptible laboratory strain. All four populations had low resistance to abamectin（resistance ratios of 9.06、8.95、13.35、6.57 fold, respectively）. Moreover, the Dongfang population had low resistance to spinosad and imidacloprid（resistance ratios of 7.11, 7.48 fold, respectively）, and the Lingao population also had low（8.28 fold） resistance to imidacloprid. [Conclusion] Excessive use of acetamiprid and abamectin should be avoided. To delay the development of insecticide resistance in T. hawaiiensis, insecticides should be used in rotation, and in combination, to control this pest.
