摘要: 【目的】白背飞虱Sogatella furcifera是水稻上的主要害虫之一,目前白背飞虱主要以化学防治为主,为指导田间合理用药,本文报道了湖北白背飞虱田间种群对防治药剂的抗性变化情况。【方法】采用稻茎浸渍法监测了2011-2014年采自湖北鄂州蒲团、鄂州长港、枝江问安和石首南口稻田的白背飞虱4个田间种群对11种杀虫剂的抗性。【结果】白背飞虱田间种群已对噻嗪酮产生中等水平抗性(抗性倍数RR=13.0~38.6倍);对吡虫啉处于敏感至中等的抗性水平(RR=2.6~15.4倍);对噻虫嗪(RR=2.1~6.9倍)、噻虫胺(RR=3.0~7.0倍)、呋虫胺(RR=2.5~7.0倍)及啶虫脒(RR=3.3~8.2倍)处于敏感至低抗水平;所有白背飞虱田间种群均对烯啶虫胺(RR=2.2~4.9倍)、异丙威(RR=2.0~4.6倍)及醚菊酯(RR=1.8~4.0倍)敏感;除长港(2011-2012年)与蒲团(2012年)白背飞虱田间种群对吡蚜酮敏感外,其余白背飞虱田间种群均对吡蚜酮产生中等水平抗性(RR=15.2~91.0倍);白背飞虱长港田间种群(2013年与2014年种群)对毒死蜱产生中等水平抗性,抗性倍数分别为15.6和10.1,其余白背飞虱田间种群则对毒死蜱为敏感或低水平抗性(RR=1.7~8.5倍)。【结论】根据监测结果, 建议加强对噻嗪酮、吡虫啉和吡蚜酮抗性监测,同时减少噻嗪酮、吡虫啉和吡蚜酮在水稻田使用次数,降低杀虫剂对白背飞虱田间种群选择压,延长其在田间的使用寿命。

Abstract: 【Aim】 The white-back planthopper, Sogatella furcifera, is a well-known serious cosmopolitan pest on rice crop. Chemical insecticides have been considered as an effective way for its control. However, field populations of S. furcifera have developed resistance to many insecticides. The objective of the present study is to monitor the insecticide resistance in field populations of S. furcifera in Hubei Province, central China, so as to provide useful information for reasonable applications of these insecticides. 【Methods】 Resistance of four field populations of S. furcifera collected form rice fields of Putuan of Ezhou, Changgang of Ezhou, Wen’an of Zhijiang and Nankou of Shishou during 2011-2014 to eleven commonly used insecticides was detected by rice stem dipping method. 【Results】 The field populations of S. furcifera have developed medium-level resistance to buprofezin [resistance ratio (RR)=13.0-38.6]. Moreover, the field populations tested showed no resistance (susceptible) to medium-level resistance to imidacloprid (RR=2.6-15.4), no resistance (susceptible) or low-level resistance to clothianidin  (RR=3.0-7.0), dinotefuran (RR=2.5-7.0), acetamiprid (RR=3.3-8.2) and thiamethoxam (RR=2.1-6.9), and maintained susceptible to nitenpyram (RR=2.2-4.9), isoprocarb (RR=2.0-4.6) and etofenprox (RR=1.8-4.0). In addition, the field populations of Changgang (2011 and 2012) and Putuan (2012) remained susceptible to pymetrozine (RR=3.1-4.9), while other populations developed moderate-level resistance to pymetrozine (RR=15.2-91.0). All populations were susceptible or showed low-level resistance to chlorpyrifos (RR=1.7-8.5) except that the field populations of Changgang (2013 and 2014) showed moderate-level resistance to chlorpyrifos (RR=15.6 and 10.1, respectively). 【Conclusion】 Due to the obvious increase in resistance to imidacloprid, buprofezin and pymetrozine, resistance monitoring is urgently needed, and applications of these insecticides should also be limited to prevent or delay further increase of insecticide resistance in S. fercifura.
