中文摘要：
通过甜菜夜蛾两种性信息素诱捕器与频振杀虫灯对甜菜夜蛾诱捕效果比较表明，两种性信息素诱捕器与频振式杀虫灯所诱到的成虫消长规律基本一致。通过SAS统计分析，干式性信息素诱捕器、水盆性信息素诱捕器和频振杀虫灯的平均诱虫量，变化趋势紧密相关，相关系数分别为r1=0．95036，r2=0．93455，r3=0．85320。但两种性信息素诱捕器的诱蛾量高于频振杀虫灯，干式诱捕器与频振灯诱蛾量差异显著（p〈0．05）。
英文摘要：
The dynamic trends of the amount of beet armyworm adults trapped by 2 trap systems with sex pheromone lures were basically consistent with that of by frequency trembler lamps. The correlations between the average adults caught by the pheromone trap systems made by the authors and that by water basin traps and frequency trembler ones were very high （r1=0.950 36, r2 =0. 934 55, r3=0. 853 2）, However, the adult amounts trapped by 2 trap systems baited with pheromone lures were more than that caught by frequency trembler lamps, and there was signifi cant difference （p〈0. 05） between the pheromone trap systems made by the authors and the frequency trembler lamps. The feasibility of the trap systems with sex pheromone lures for application in practice for forecasting the population dynamics of beet armyworm was discussed.
