鉴于蚂蚁社会中雌性蚂蚁复杂的交流能力及其相关的化学生态学和感官生理学，雄性蚂蚁在很大程度上被忽视，因此，对它们的嗅觉感官能力知之甚少。为了解决这一问题，我们探讨了外周气味敏感性在男性Harpegnathos saltator通过测量嗅觉感觉神经元的电生理活动，触角触角和腔锥感器使用细胞外记录技术。在一个小组的46种化合物的初步试验中，感器candredea强烈响应两个报警信息素成分，而数量有限的一般气味剂引起强烈的反应，在感器coeloconica和两种感觉器类型是漠不关心的31表皮碳氢化合物（CHCs）。在一个专门的搜索CHC响应感器和一个较小的面板的六种化合物，我们发现一些感器，响应于合成CHC和CHC从处女皇后咽后腺，这是潜在的用于近距离的配偶识别。雄蚁对15种常见气味的嗅觉生物测定证实了其感觉反应与相应的行为反应。总的来说，当比较H。跳跃者雄性和雌性中，我们发现工人的腔锥感器和锥形感器对所有递送的化合物都表现出更强的反应和更广泛的选择性。罕见的CHC响应的鱼形感器在Harpegnathos男性暗示一个特定的作用，在性交流相比，女性使用CHC在更广泛的通信和识别的背景下，并有强烈的感器响应范围广泛的CHC。
In light of the sophisticated communication abilities of females in ant societies and their associated chemical ecology and sensory physiology, male ants are largely ignored and accordingly, little is known about their olfactory sensory capabilities. To address this, we explored peripheral odor sensitivities in male Harpegnathos saltator by measuring the electrophysiological activity of olfactory sensory neurons housed within antennal trichoid and coeloconic sensilla using an extracellular recording technique. In an initial trial against a panel of 46 compounds, sensilla trichodea responded strongly to two alarm pheromone components, while a limited number of general odorants elicited strong responses in sensilla coeloconica and both sensillar types were indifferent to 31 cuticular hydrocarbons (CHCs). In a dedicated search for CHC-responding sensilla and a smaller panel of six compounds, we found some sensilla that responded to a synthetic CHC and CHCs from virgin queen postpharyngeal glands which are potentially used for close range mate recognition. Olfactometric bioassays of male ants with 15 general odors corroborated the sensory responsiveness with respective behavioral responses. Overall, when comparing olfactory responses between H. saltator males and females, we found that sensilla coeloconica and basiconica of workers showed stronger responses and broader selectivity to all delivered compounds. The rarity of CHC-responding trichoid sensilla in Harpegnathos males hints to a specific role in sexual communication compared to females that use CHCs in a broader communication and identification context and that have sensilla responding robustly to a broad range of CHCs.
