Two species of predatory beetles that locate their prey, Ips pini, by responding to its aggregation pheromone have different chiral preferences to ispdienol than does the herbivore. This suggests that chiral disparity may provide some escape for bark beetles from predation, and that geographic variation in herbivore communication systems may be partially due to predator - imposed selection pressures. These results also suggest ways in which the semiochemical and biological control of North America's most damaging group of forest insects can be improved.
两种通过对其聚集信息素做出反应来定位猎物——北美松树小蠹（Ips pini）的捕食性甲虫，与食草动物相比，对异长叶烯醇具有不同的手性偏好。这表明手性差异可能为树皮甲虫提供了一些躲避捕食的途径，并且食草动物通讯系统中的地理变异可能部分归因于捕食者施加的选择压力。这些结果还提出了一些可以改进对北美最具破坏性的森林昆虫群体进行信息化学和生物防治的方法。
