摘要: [目的] 研究颜色改进型暗褐色拦截挡板诱捕器诱捕效果;将缓释的1-戊醇和2-戊醇单独或与信息素组合后,结合颜色改进型暗褐色诱捕器进行田间诱捕试验,探究对光肩星天牛的引诱效果,以期开发监测光肩星天牛的有效工具。[方法] 在每个样地用尼龙绳分别将32个诱捕器(4种引诱剂×4种释放率×2种颜色)悬挂在柳树枝干上,3个样地共悬挂96个诱捕器。每天检查一遍诱捕器,统计、鉴定诱捕到的光肩星天牛的雌、雄数量。[结果] 诱捕器颜色显著影响对光肩星天牛的引诱效果,暗褐色诱捕器的平均诱捕量为1.521头,显著高于黑色诱捕器的平均诱捕量1.063头(t=4.854,P=0.047),暗褐色诱捕器诱捕到的天牛雌性比为0.58,黑色诱捕器诱捕到的雌性比仅为0.45。在大约8周的田间诱捕期内,缓释量为135 mg·d-1的1-戊醇和2-戊醇与褐色诱捕器组合,诱捕到的光肩星天牛数量均最多(8头),诱到天牛的雌性比分别为0.50和0.63。添加雄性信息素后,进一步增强了缓释量为135 mg·d-1的1-戊醇或2-戊醇与褐色诱捕器组合对光肩星天牛的诱捕效果,尤其增强对雌性的诱捕效果,使诱到天牛的雌性比分别提高到0.55和0.67。[结论] 可将暗褐色诱捕器与添加雄性信息素的释放量为135 mg·d-1的1-戊醇或2-戊醇组合,作为监测光肩星天牛发生动态的有效工具。

Abstract: [Objective] This study aims to test trap efficiency of an improved brown color trap for baiting Anoplophora glabripennis (Asian longhorned beetle, ALB), this experiment was conducted in the field with sustained-releasing 1-pentanol or 2-pentanol, combined with male pheromone, to develop an efficiency tool for monitoring and control ALB. [Method] Thirty-two traps (four attractants × four releases × two color traps) were hung with nylon ropes on branches of Salix matsudana in each sample plot, and there were ninety-six traps in three sample plots. The traps were checked and recorded for the numbers of males and females captured every day. [Result] Trap color had a significant effect on efficiency of capturing beetles. Compared with no-modified color traps (with which the average number of captured beetles was 1.063), the average number of brown modified traps captured beetles was significantly higher (t=4.854,P=0.047) with 1.521 individuals and the female ratio of 0.58. When 1-pentanol or 2-pentanol was 135 mg·d-1 at sustained-release rate, with brown traps, the highest number of ALB captured was eight and female ratio was 0.50 and 0.63, respectively. Addition of the male pheromone significantly enhanced the trap efficiency of ALB, and the female ratio was 0.55 and 0.67, respectively. [Conclusion] The brown trap with 1-pentanol, or 2-pentanol at release rate of 135 mg·d-1, combined with male pheromone was a useful tool for monitoring and controlling ALB in the field.
