Methylbutenol (MBO) is a major component of the aggregation pheromone of the European spruce beetle Ips typographus and also has been found to be emitted in large amounts by several species of pine native to western North America. This study investigates the influence this signal may have on the behavior of North American bark beetles and examines whether MBO functions as a defensive compound for emitting pines. The response of two North American bark beetles (Ips paraconfusus and Dendroctonus brevicomis) and their predaceous beetles (Trogositidae and Cleridae) to MBO, pheromone, and monoterpenes in varying release rates was investigated in the field using Lindgren funnel traps. MBO exhibited no repellent properties when tested alone, nor did MBO appear to have any effect on the aggregation response of these bark beetles and their predators to their pheromones. These results provide no support for a defensive function of MBO.
甲基丁烯醇（MBO）是欧洲云杉八齿小蠹聚集信息素的主要成分，并且人们还发现北美洲西部原产的几种松树会大量释放这种物质。本研究调查了该信号可能对北美树皮甲虫行为产生的影响，并研究了MBO是否作为释放MBO的松树的防御性化合物发挥作用。在野外使用林格伦漏斗诱捕器，研究了两种北美树皮甲虫（拟混淆材小蠹和短角材小蠹）及其捕食性甲虫（扁甲科和郭公甲科）对不同释放速率的MBO、信息素和单萜的反应。单独测试时，MBO没有驱避特性，而且MBO似乎对这些树皮甲虫及其捕食者对其信息素的聚集反应也没有任何影响。这些结果不支持MBO具有防御功能的观点。
