本研究用15种杀虫剂对抗药性棉铃虫进行了室内杀虫作用测定和田间药效试验,以选出在棉铃虫不同发生世代应用的有效药剂。结果表明,对二代棉铃虫的防治效果达80％以上的药剂有50％棉铃宝、44％多虫清、25％广克威、20％灭多威、30％灭铃灵和35％硫丹等12种。对三代棉铃虫的防效达80％以上的仅有棉铃宝、多虫清、广克威等6种。15种药剂中对二、三代棉铃虫的药效及室内杀虫效果排在前三位的均为混剂。提出混剂将在目前抗药性棉铃虫防治中发挥重要作用。 In this study, 15 pesticides were tested against insecticidal cotton bollworm insecticide indoor efficacy and field trials to select effective agents in different generations of cotton bollworm generation. The results showed that 50% cotton bollworm, 44% multifungia, 25% glocculant, 20% methomyl, 30% chlorserine and 35% sulfur Dan and other 12 species. On the three generations of cotton bollworm control effect of more than 80% of the only cotton bollworm, multi-worm clear, such as 6 grams Kwong Wei. 15 kinds of agents on the second and third generations of cotton bollworm efficacy and indoor insecticidal effect in the top three are mixed. It is suggested that the mixture will play an important role in the current control of cotton bollworm.
