我们先前的研究显示，白蚁，Coptotermes formosanus Shiraki（等翅目：鼻白蚁科），通过相互梳理行为来保护自己免受昆虫病原真菌的侵害。白蚁通过相互梳理行为从其巢友的体表移除并丢弃外来生物，例如真菌分生孢子。本文探讨了触角在探测条件中的作用。使用三种昆虫病原真菌，布氏白僵菌782（Saccardo）（肉座菌目）、玫烟色拟青霉K3（Wize）（丝孢菌纲）和金龟子绿僵菌455 Sorokin（丝孢菌纲）。有触角的白蚁比无触角的白蚁更有效地去除分生孢子。有触角和无触角的白蚁在选择理毛地点、理毛时间和理毛发生率上存在差异。白蚁触角的触角电位（EAG）反应波形对作为气味源的真菌种类有很强的特异性。白蚁在取食试验中能够区分所测试的真菌。这些结果表明，触角在白蚁的相互理毛行为中起着重要作用。
Our previous research has shown that the termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), protects itself from entomopathogenic fungi by mutual grooming behavior. The termite removes and discards foreign organisms, such as fungal conidia, from the body surface of its nestmates by mutual grooming behavior. The role of the antennae in detecting the condia was examind here. Three entomopathogenic fungi were used, Beauveria brongniartii 782 (Saccardo) (Hypocreales), Paecilomyces fumosoroseus K3 (Wize) (Hyphomycetes), and Metarhizium anisopliae 455 Sorokin (Hyphomycetes). Termites with antennae removed conidia more efficiently than termites without antennae. There were differences between termites with and without antennae in selection of sites to be groomed on nestmates, in the length of grooming and in occurrence of grooming. Electroantennogram (EAG) responses were recorded from termite antennae and the waveforms were rather specific to the kinds of fungi used as odor sources. Termites were able to distinguish between the tested fungi in feeding tests. These results show that the antennae play important roles in the mutual grooming behavior of the termite.
