摘　　要：为了明确沙蒿木蠹蛾性信息素的诱捕距离和效果,在受害的黑沙蒿林外,主要风向的上风向、下风向及侧风向区域分别等距离设置7个诱捕器。诱捕结果表明:上风向的诱捕效果最好,诱捕量占到诱捕总量的60%,侧风向的效果好于下风向;在上风向设置的不同距离的诱捕器中,距林缘30～210m处均能诱捕到成虫,但以60m处诱捕到的数量最多;该性信息素的持效期为25～34d;3种不同类型诱捕器的野外诱捕效果显示,船形和三角形诱捕器的诱捕效果明显好于实用新型诱捕器。除了沙蒿木蠹蛾,该性信息素还对草地螟、冬麦异夜蛾和蜂虻等有较明显的诱捕效果。The trapping effect and distance of the sex attractant for Holcocerus artemisiae was tested with seven traps set equidistantly from damaged Artemisia ordosica in the upwind,downwind and crosswind directions,respectively.The upwind trap was optimal（accounting for 60% of males） and crosswind trap was better than that in the downwind direction.Males were trapped at the distances of 30 210 m upwind,with the largest capture number at 60 m.The sex pheromone could last up to 25 34 days.The boat and triangle traps were effective than novel practical type.In addition to H.artemisiae,the sex attractant also attracted Loxostege sticticalis,Protexarnis squalid and Bombyliidae species.
