上海地区是从1981年开始在棉花、蔬菜、果树等作物上普遍使用拟除菊酯,主要是用杀灭菊酯。为了掌握杀灭菊酯对害虫的毒效动态,了解害虫产生抗药性的可能性及其发展速度,我们在1979年开始药效试验的同时,就着手进行毒力检测工作。现将检测情况综述如下。 Shanghai area is from 1981 onwards in cotton, vegetables, fruit trees and other crops commonly used in the synthesis of pyrethrins, mainly with fenvalerate. In order to master the toxic effects of pyrethrins on pests and to understand the possibility of pest resistance and its speed of development, we began to conduct virulence tests at the same time we started the efficacy test in 1979. Now the detection of the situation are summarized below.
