各种生物向竞争对手发出恶臭分泌物，应研究这些分泌物在害虫管理中的潜在用途。例如，一些蚂蚁种类以与屎壳郎相似的资源为食，这可能导致屎壳郎产生对抗化学防御的能力。我们测试了屎壳虫Canthon smaragdulus (Fabricius)（鞘翅目：金龟科，金龟科）的蛹分泌物是否会改变外来城市害虫Tapinoma melanocephalum (Fabricius)（膜翅目：蚁科）的运动行为，特别是这些分泌物是否会排斥这些蚂蚁。我们还测试了黑头t猴运动行为的紊乱是否随着pygidial分泌量的增加而增加。我们发现，当暴露于偶联屎壳郎、单雄屎壳郎和单雌屎壳郎的蛹分泌物时，个体黑头t虫的运动行为发生了变化。此外，雄性和雌性蜣螂的蛹分泌物可以击退蚂蚁。黑头金鼠运动行为的变化随着核分泌量的增加而增加。我们的结果表明，屎壳虫的蛹分泌物具有作为黑头绦虫生物驱避剂的潜力。因此，蜣螂的蛹分泌物可能在未来用于城市害虫管理策略的发展。
Various organisms emit malodorous secretions against competitors, and the potential use of these secretions in pest management should be investigated. For example, some ant species feed on similar resources as dung beetles, which might have led to counter chemical defences in dung beetles. We tested whether pygidial secretions of the dung beetle Canthon smaragdulus (Fabricius) (Coleoptera: Scarabaeidae, Scarabaeinae) alter the locomotor behaviour of the exotic urban pest ant Tapinoma melanocephalum (Fabricius) (Hymenoptera: Formicidae), specifically whether these secretions repel those ants. We also tested whether the disturbance in the locomotor behaviour of T. melanocephalum increases with the amount of pygidial secretion. We found that individual T. melanocephalum displayed changes in their locomotor behaviour when exposed to pygidial secretions of coupled dung beetles, single males, and single females. Additionally, the pygidial secretions from male and female dung beetles could repel ants. The change in the locomotor behaviour of T. melanocephalum increased with the amount of pygidial secretion. Our results suggest that the pygidial secretions of dung beetles have potential as a biological repellent of T. melanocephalum. Hence, pygidial secretions from dung beetles may be used in the future for the development of urban pest management strategies.
