使用杀虫剂防治水稻害虫,往往对害虫的重要天敌——蜘蛛也大量杀伤。为协调化学防治和生物防治,探讨如何保护天敌,以便更好地发挥天敌的作用,我们进行了本试验。试验于1981年在广东始兴县生防站和城南公社进行。通过室内对蜘蛛和害虫的毒力测定,比较几种杀虫剂的毒性。在防治害虫的同时,调查杀虫剂对蜘蛛的影响。一、供试杀虫剂 25％杀虫双水剂(中山石岐农药厂)。25％杀虫脒水剂(中山石岐农药厂),40％乐果乳油(北京农药厂),40％叶飞散乳油(江门农药厂),1％乙基1605混3％666粉剂(简称乙六粉,珠江电化厂),1.5％甲基1605混3％666粉剂(简
The use of pesticides to control rice pests, often the main predators of pests - spiders also mass killings. In order to coordinate chemical control and biological control, explore ways to protect natural enemies in order to better play the role of natural enemies, we conducted this experiment. The experiment was conducted in 1981 in Shixing Health Station and Chengnan Commune. The indoor toxicity of spiders and pests was compared to compare the toxicity of several insecticides. Pest control in the same time, the impact of pesticides on the spiders. First, the test pesticides 25% insecticide double agent (Zhongshan Shiqi Pesticide Factory). 25% Chlordimeform Aqua (Zhongshan Shiqi Pesticide Factory), 40% dimethoate (Beijing Pesticide Factory), 40% Yefei Sanju EC (Jiangmen Pesticide Factory), 1% Ethyl 1605 mixed 3% 666 powder Six powder, Pearl River Electrochemical Factory), 1.5% methyl 1605 mixed 3% 666 powder (Jane
