| 摘 要： | 以安徽太湖县敏感地区二化螟（Chilo suppressalis Wallker)自然种群为敏感种群，根据用药水平差异，有代表性地选用浙江，江苏和安徽3地区田间种群，监测了二化螟对杀虫单等4种杀虫剂的抗性水平，结果表明：（1）浙江慈溪二化螟3幼译杀虫单已产生高水平抗性（RR＝54．6），对杀螟松产生了中等水平抗性（RR＝13．9），对敌敌 氰戊菊酯仍较敏感；（2）安徽安庆二化螟3龄幼虫对杀虫单处于中抗水平（RR＝10．8），对杀螟松，敌短短 畏和氰戊菊酯仍较敏感。（3）江苏兴化二化螟3龄幼虫与安庆相似，对杀虫单中抗（RR＝12．6），对其它被试药剂仍较敏感；（4）不同地区用3龄和6龄幼虫测定的抗药性水平相近，同时用太湖敏感种群和慈溪高抗种群进行的增效试验表明，TPP 对杀虫单无增效作用，但PBO在抗性种群中对杀虫单有 一定的增效作用，说明该种群对杀蝗抗性与多功能氧化酶有一定的关系。

| 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. |
