摘　　要：2003年在贵州省黔南州都匀茶场进行了性信息素迷向法防治茶毛虫Euproctis pseudoconspersaStrand的田间试验。通过比较处理区和对照区内茶毛虫发蛾量、交配率和后代虫口密度,发现剂量为0.5mg的性信息素释放器按5 m的间隔施放的防治效果显著好于其它处理,它在越冬代和第1代试验中茶毛虫诱蛾量分别减少83.90%和70.25%,交配率分别下降78.18%和73.21%,虫口密度减少59.02%和45.71%。试验结果表明性信息素迷向法可以作为防治茶毛虫的一种手段。Field experiments were conducted to evaluate the effect of mating disruption with sex pheromone on population of tea tussock moth, Euproctis pseudoconspersa Strand in Duyun tea plantation farms located in Guizhou, a southern province of China in 2003. The eontrol efficacy was optimized when dispensers containing 0.5 mg sex pheromone lure were placed at 5 m intervals. Male moth catch rate, mating rate, larva and egg density reduced by 83.90% and 70.25%, 78.18% and 73.21% ,59.02% and 45.71% respectively, compared with that of untreated field in overwintering and first generation experiment. The result of this experiment indicated that mating disruption method with sex pheromone lure could act as an agent in controlling tea tussock moth.
