Abstract：Objective To investigate the change of the resistance of Cluex quinquefasciatus to beta-cypermethrin,tetramethrin and deltamethrinin different regions of Jiangxi Province.Methods Larva soaking method was used in this bioassay.Results Compared with the data in 2014,the resistance ratios (RR) of Cluex quinquefasciatus to betacypermethrin in Fuzhou,Jiujiang and Xinyu were up to 21.06,3.78 and 6.98,while the RRs to tetramethrin in these cities were up to 6.8,0.63 and 3.Moreover,the RRs to deltamethrin were up to 7.67,4.87 and 5.34.Resistances of Cluex quinquefasciatus Shangrao and Jianto those insecticides were in middle or high level.Conclusion In order to delay resistance evolution,alternating the pesticides is important,so as the integrated management should be promoted.
