Abstract
Bioassay was taken to determine the susceptibility of the rice stem borer,Chilo suppressalis Walker,collected from Taihu County ,Anhui Province.After compared with the reported data,the results were taken as relatively susceptible base line data.Field strains of rice stem borer from Zhej iang,Anhui and Jiangsu Provinces were collected and monitored for resistance.Res ults showed that:(1)In Cixi County,Zhejiang Province,high-level resistance was developed to monosultap(RR＝54.6)，median-level to fenitrothion(RR＝13.9),but susceptibility still remained to DDVP and fenvalerate.(2)In Anqing County,Anhui Province,only median-level resistance was found to monosultap(RR＝10.8).No re sistance was found to fenitrothion,DDVP and fenvalerate.(3)In Xinghua County,Jia ngsu Province,similar as in Anqing County,median-level resistance was developed to monosultap(RR＝12.6).No resistance was found to other tested insecticides. (4)Bioassay with 6th instar or 3rd instar larvae gave similar results as expressed in resistance level.Furthermore,synergistic test with PBO and TPP,inhibitor of MFO and esterase,respectively,revealed that TPP had no synergism to monosultap in both susceptible and resistant populations,but PBO shown a little synergism in the resistant population,indicating MFO may be involved in the resistance mechanism.关键词
