摘　　要：为明确2023年中国华南稻区褐飞虱的抗药性现状,采用稻茎浸渍法监测了华南地区4省7个褐飞虱田间种群对10种常用杀虫剂的抗药性情况。结果表明:褐飞虱对3种已暂停用于该害虫防治的药剂噻嗪酮(876.2~5151.2倍)、吡虫啉(3534.0~9949.9倍)和噻虫嗪(1253.8~2668.3倍)仍具有高水平抗药性且呈继续上升趋势;对呋虫胺(49.4~482.5倍)、吡蚜酮(77.2~351.3倍)、烯啶虫胺(16.6~106.4倍)和毒死蜱(20.7~105.3倍)已达到中等至高水平抗药性,对氟啶虫胺腈(13.2~46.0倍)为中等水平抗药性;对三氟苯嘧啶(2.3~8.6倍)为敏感至低水平抗药性,对醚菊酯(1.0倍)仍为敏感水平。因此推荐在该区域稻区可轮换使用三氟苯嘧啶和醚菊酯等不同作用机制的药剂防控褐飞虱,结果可为褐飞虱的田间抗药性治理提供参考。In order to clarify the current resistance status of Nilaparvata lugens in the rice-growing areas of South China in 2023,the rice stem dipping method was adopted to monitor the resistance of 7 field populations of N.lugens in 4 provinces in South China to 10 commonly used insecticides.The results showed that N.lugens still had a high level of resistance to three pesticides that had been suspended for the control of this pest,namely buprofezin(876.2-5151.2 fold),imidacloprid(3534.0-9949.9 fold)and thiamethoxam(1253.8-2668.3 fold),and the resistance continued to show an upward trend.It had reached a moderate to high level of resistance to dinotefuran(49.4-482.5 fold),pymetrozine(77.2-351.3 fold),nitenpyram(16.6-106.4 fold)and chlorpyrifos(20.7-105.3 fold),and had a moderate level of resistance to sulfoxaflor(13.2-46.0 fold).It had a sensitive to low level of resistance to triflumezopyrim(2.3-8.6 fold)and still remained at a sensitive level to etofenprox(1.0 fold).Therefore,it is recommended that insecticides with different action mechanisms such as triflumezopyrim and etofenprox can be used alternately to control N.lugens in the rice-growing areas in this region.The results can provide a reference for the management of field resistance of N.lugens.
