中文摘要：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。
英文摘要：Methods of insecticide resistance monitoring, including microtopical and rice seedling dipping methods, adapted for resistance monitoring in the striped stem borer, are introduced. The topical method is used to bioassay contact insecticides. However, this method does not accurately reflect the activity of insecticides which act after being ingested. The rice seedling dipping technique was therefore established to detect resistance to insecticides that require ingestion, such as diamides and Bt microbial insecticides.
