在互惠共生中，伙伴歧视往往是相互作用的生物体面临的最重要的挑战。蚂蚁和蚜虫之间的相互作用是研究互惠关系的模型系统;蚂蚁由蚜虫提供蜜露，反过来，蚂蚁为蚜虫提供有益的服务。为了建立和维持这一系统，蚂蚁必须正确区分互惠共生的蚜虫种类。虽然最近的研究表明，蚂蚁识别蚜虫作为互利合作伙伴的基础上，他们的表皮碳氢化合物（CHCs），这是不清楚的CHCs参与识别。在这里，我们测试是否当时的烷烃或甲基烷烃馏分，或两者，蚜虫CHCs被用作合作伙伴识别线索，通过测量蚂蚁对这些馏分的侵略性。当Tetramorium tsushimaeants的工人提出了与他们的互惠蚜虫Aphis craccivora的正构烷烃涂层假人，蚂蚁表现出更高的侵略水平比假人处理总CHCs或甲基烷烃的A。craccivora;对用A. craccivora与对照假人或用非互惠蚜虫Acyrthosiphon pisum的CHC处理的假人的那些相似。相比之下，蚂蚁表现出较低的侵略假人与总CHCs或甲基烷烃部分的互惠蚜虫比对照假人或假人处理与CHCs的非互惠蚜虫。这些结果表明T. tsushimaeans使用的甲基烷烃的互惠蚜虫的CHCs识别合作伙伴，这些蚂蚁不承认蚜虫作为合作伙伴的基础上的正构烷烃。
In mutualisms, partner discrimination is often the most important challenge for interacting organisms. The interaction between ants and aphids is a model system for studying mutualisms; ants are provided with honeydew by aphids and, in turn, the ants offer beneficial services to the aphids. To establish and maintain this system, ants must discriminate mutualistic aphid species correctly. Although recent studies have shown that ants recognize aphids as mutualistic partners based on their cuticular hydrocarbons (CHCs), it was unclear which CHCs are involved in recognition. Here, we tested whether then-alkane or methylalkane fraction, or both, of aphid CHCs were utilized as partner recognition cues by measuring ant aggressiveness toward these fractions. When workers ofTetramorium tsushimaeants were presented with dummies coated withn-alkanes of their mutualistic aphidAphis craccivora, ants displayed higher levels of aggression than to dummies treated with total CHCs or methyl alkanes ofA. craccivora; responses to dummies treated withn-alkanes ofA. craccivorawere similar to those to control dummies or dummies treated with the CHCs of the non-mutualistic aphidAcyrthosiphon pisum. By contrast, ants exhibited lower aggression to dummies treated with either total CHCs or the methylalkane fraction of the mutualistic aphid than to control dummies or dummies treated with CHCs of the non-mutualistic aphid. These results suggest thatT. tsushimaeants use methylalkanes of the mutualistic aphid’s CHCs to recognize partners, and that these ants do not recognize aphids as partners on the basis ofn-alkanes.
