摘      要：The brown planthopper is a notorious rice pest in many areas of *** evolution of insecticide resistance in Nilaparvata lugens has become a serious problem in the effective control of this pest in the paddy *** this article,the current susceptibility of *** field populations to novel mesoionic insecticide triflumezopyrim and major classes of chemical insecticides was determined and *** monitoring results indicated that field populations of *** had developed low resistance to triflumezopyrim(resistance ratio,RR:1.3-7.3-fold)during 2015-2018 in China,and the median lethal concentration values varied from 0.05 to 0.29 mg/***,during 2017 to 2018,field populations of *** showed high resistance levels to thiamethoxam(RR:456.1-1025.6-fold),imidacloprid(RR:2195.3-6899.0-fold)and buprofezin(RR:1241.57521.7-fold),moderate to high resistance levels to dinotefuran(RR:97.6-320.1-fold),clothianidin(RR:69.4-230.1-fold)and isoprocarb(RR:44.1-108.0-fold),and low to moderate levels of resistance to chlorpyrifos(RR:12.0-29.7-fold)and nitenpyram(RR:6.9-24.1-fold).In contrast,*** just showed low resistance to sulfoxaflor(RR:3.3-8.5-fold)and etofenprox(RR:5.0-9.1-fold)in the ***,the P450 gene CYP6ER1 was found to be significantly overexpressed in all five field populations of *** collected in 2018 when compared with a laboratory susceptible *** findings will provide useful information to delay the evolution of insecticide resistance in ***.
