摘　　要：通过对广东地区的抗性锈赤扁谷盗采用一次性施药和多次施药方式的杀虫试验,均达到彻底杀灭抗性锈赤扁谷盗的目的。说明对抗性害虫的熏蒸防治,应充分重视熏蒸时的最低有效浓度以及有效浓度的保持时间,只有两个条件都达到,才能取得对抗性害虫的防治效果,同时也阐明了熏蒸后期害虫检查的必要性以及对抗性害虫"杀必彻底"的原则。The resistant Cryptolestes Ferrugineus（Stephens） could be controlled completely by one and several times application in Guangdong area.The test indicated that in fumigation against resistant insect pests,the minimum effective concentration and exposure time should be paid great attention during fumigation.Only when these two conditions meet the requirements of fumigation,the control effect against resistant insects might be gained.It also illustrated that there was necessary to check the fumigation effect in post fumigation and thoroughly kill resistant insect pests.
