Abstract

The nasute soldiers of the neotropical termite Nasutitermes costalis function as scouts by exploring new terrain for food in advance of the worker caste and regulate foraging activity by laying trails composed of sternal gland pheromone. Additional soldiers are at first recruited in large numbers, and subsequently workers appear as the pheromone concentration increases. The role of the nasutes in the organization of foraging is extremely unusual for the soldier caste in social insects and appears to be a component of a foraging/defense system that controls the recruitment of foragers and effectively deters attacks by ants, the most fierce and important predators of termites.

摘要

新大陆乳白蚁 Nasutitermes costalis 的兵蚁作为侦察兵,在工蚁之前探索新的觅食地形,并通过铺设由胸腺信息素组成的轨迹来调节觅食活动。最初会招募大量的额外兵蚁,随着信息素浓度的增加,工蚁随后出现。兵蚁在觅食组织中的作用在社会性昆虫的兵蚁中极为不寻常,似乎是一种觅食/防御系统的组成部分,该系统控制着觅食者的招募,并有效地阻止了最凶猛和最重要的白蚁捕食者——蚂蚁的攻击。
