摘要
本试验选用了三种菊酯类农药敌杀死、灭扫利、功夫乳油和大田常用农药氧化乐果对宁夏中宁县郭庄枸杞蚜虫进行了抗性测定。其结果：从１９８５年至１９９５年枸杞蚜虫对敌杀死、歹扫利的抗性发展最快，分别达２７３８．０６及１１２２．５６倍，其次为功夫，抗性达３０５倍。分析了抗性发展的原因，提出了减缓枸杞蚜虫产生抗性的对策。
The experiment selected three kinds of pyrethrins(dlxametrin,fenpropathrin,lambde-cyhalothrin/pp321)and omethoate(a normal pestcide)to test the drug fast of the wolfberry aphid in Zhongning County of Ningxia. The result showed that the drug fast of wolfberry aphid to delxa metrin and fenpropathrin/pp321 occurred most rapidly in three pestcides,their rapidity were 2738.06 and 1152.56 times of the omethoate's rapidity of drugfast,then the lambd-cyhalothrin/pp321,305 times in 1985--1995.The cause of drug fast was analysed, and put farward the policy for retarding drug fast to the pests insect.
