浙江省主要害虫抗药性发展现状及治理策略综述

Status on Management Strategies of the Insecticide Resistance to Agricultural Insects in Zhejiang Province

本文报道了浙江省５种作物的９种害虫对２２种药剂抗性监测结果。其中二化螟对杀虫双、杀虫单、甲胺磷，棉铃虫和棉红铃虫、马尾松毛虫对溴氰菊酯，柑桔全爪螨对水胺硫磷、灭扫利、三氯杀螨醇，菜青虫和马尾松毛虫对敌百虫等均产生较高的抗性水平。同时，通过１９９２～１９９７年抗性治理研究，提出了抗性治理对策，通过实施和跟踪监测，慈溪棉红铃虫对氰戊菊酯的抗性从２８．６倍下降到１４．３倍，龙游柑桔全爪螨对氧化乐果、尼索朗、霸螨灵、双甲脒的抗性指数分别下降９．４９倍、０．７１倍、１０．９３倍和１６．１９倍。

The resistance of nine insects on five crops to 22 insecticides in Zhejinag province were introduced in this paper. The higher resistant level of chilo suppressalis to shacongshuang, shacongdan and methamidophos; Heliothis amigera Hbner, pectinophora gossypiella, Dendrolimus.Punctatus to deltamethrin;Panonycnus Citri to isocarbophos, fenpropathrin and dicofol; pieris rapae, Dendrolimus.Punctatus to trichlorphon were observed. Resistance management were carried out during 19921997 and the minitoring results were showed that the resistant index of pectinophora gossypiella in Cixi to fenvalerate falled from 28.6fold to 14.3fold and that of panonychus citri in Longyou to omethoate, hexythiazox, fenpyroximate, amitraz falled 9.49 fold, 0.71 fold, 10.93 fold, 16.19 fold respectively.
