本文首先介绍了二化螟Chilo suppressalis(Walker)抗药性监测的方法:点滴法和稻苗浸渍法。其中点滴法已有标准化的生测规程,其适用于以触杀作用为主的杀虫剂抗性监测,但无法准确反映以胃毒作用为主的杀虫剂的毒力效果,因此,本文新建了以胃毒作用为主的双酰胺类或微生物杀虫剂Bt等的抗性监测方法———稻苗浸渍法。
This article first introduced the Chilo suppressalis (Walker) resistance monitoring method: drip method and rice seedling immersion method. Thereinto, the standard method of bioassay has been applied to the drop method, which is suitable for the insecticide resistance monitoring based on the contact action but can not accurately reflect the toxicity effect of the insecticide mainly on the stomach toxicity. Therefore, To stomach poisoning based bisamide or microbial pesticides Bt and other resistance monitoring method --- rice seedling immersion method.
