摘要
采用浸渍法,在室内用吡虫啉对桃蚜敏感种群进行抗性选育,经过15代的连续汰选,获得抗性指数为14.34倍的抗吡虫啉桃蚜种群。对9种常用杀虫剂的交互抗性测定结果表明,该种群对拟除虫菊酯类如高效氯氟氰菊酯(抗性指数12.76倍)和溴氰菊酯(10.24倍),有机磷类如氧乐果(7.95倍)、辛硫磷(5.44倍)和甲胺磷(5.32倍)以及吡虫啉.高效氯氰菊酯混剂(8.90倍)均产生了不同程度的交互抗性,而对氨基甲酸酯类如灭多威(3.15倍)、有机氯类如硫丹(1.64倍)以及阿维菌素.辛硫磷混剂(2.31倍)等无明显的交互抗性。
The resistant strain of peach-potato aphid, Myzus persicae （Sulzer） to imidacloprid was continuously selected by leaf-dip bioassay in the laboratory. The imidacloprid-resistant strain with 14.34-fold resistance was developed after 15-generation selection. The cross-resistances of the imidacloprid-resistant strain to nine insecticides commonly used in the tobacco field were also measured. It appeared to have positive cross-resistance to pyrethroids including lambda-cyhalothrin （resistance index was 12.76-fold） and deltamethrin （10.24-fold）. It also had cross-resistance to organophosphates such as omethoate （7.95-fold）, phoxim （5.44-fold）, methamidophos （5.32-fold） and the mixture of imidacloprid and beta-cypermethrin （8.90-fold）. However, it had no cross-resistance to carbamate （ methomyl）, organochlorine （endosulfan） and the mixture of abamectin and phoxim.
