摘　　要：杨树枝把是棉铃虫预测预报和防治的重要手段之一,其使用效果在棉铃虫的3、4代发生期更优于性诱剂。概述了诱集棉铃虫的杨树枝把制作、使用技术及作用效果,分析了杨枝把诱集棉铃虫的性别、代次差异,诱集时间的特异性,以及杨树枝叶挥发性物质的分离提取,室内分析与田间诱集测试,阐述了棉铃虫诱集杨树枝把的作用机理,并分析了杨树枝把在害虫防治中的应用前景。Technique of the trapping cotton bollworm （Helicoverpa armigera Hubner） with poplar branch bundles is one of prediction and control strategies of cotton bollworm, which application effect on the 3rd and 4th generation is better than that of sex pheromone attractants. This paper presents the making and application of poplar branch bundles and its effect, and introduces difference of sex and different generations of the trapped cotton bollworm, time specificity of the trapping cotton bollworm with poplar branch bun- dies, and volatilizing odor components extracted from the branch and leaves of poplar, and testing the odor components in the lab and field. Study on technique of the trapping cotton bollworm with poplar branch bundles and its mechanism is reviewed, then its developmental prospect in insect pest control is presented.
