Trail pheromones mediate communication among western subterranean termites, Reticulitermes hesperus Banks. Repetitive passages of >or=28 termites were required to establish a pheromone trail and trails needed to be reinforced because they lasted <48 hr. The minimal threshold concentration for inducing responses from termite workers and secondary reproductives was between 0.01 and 0.1 fg/cm of (3Z,6Z
尾信息素介导了西部地下白蚁(Reticulitermes hesperus Banks)之间的交流。需要重复通过≥28个白蚁才能建立信息素路径,并且由于路径持续时间少于48小时,因此需要对其进行加固。诱导白蚁工作者和次级生殖器官反应的最低阈值浓度在(3Z,6Z,8E)-十二碳三烯-1-醇(以下称为十二碳三烯酚)的0.01至0.1 fg / cm之间。工人在浓度为10 fg / cm时对十二碳三烯酚表现出最佳的跟踪行为。浓度> 10 pg / cm的步道对工人是排斥的。工人没有检测到信息素梯度,对十二碳三烯酚的增加或减少梯度均能做出反应,白蚁工人无法区分十二碳三烯酚的不同浓度。白蚁优选十二碳三烯酚的踪迹比2-苯氧基乙醇的踪迹好。天线在线索信息素的感知中起着关键作用。十二碳三烯酚可作为工蚁(10 fg / cm2)和雄性白蚁(5 ng / cm2)的避雷剂,而雌性的胸骨腺提取物则吸引了雄性白蚁
