血桐Myrmecophytes港口物种特异性Crematogaster蚂蚁，捍卫宿主树木从食草动物。我们研究了蚂蚁的侵略行为时，人工损坏的叶片从另一棵树提供给四个同域种专性血桐myrmecophytes。蚂蚁表现出侵略性的行为，在响应叶片，无论叶种，然而，侵略性较高时，同种叶片提供比非宿主物种提供。因此，蚂蚁可以识别叶片损伤并区分受损的叶片种类。从受损的叶子，可能会引起蚂蚁防御挥发性化合物的化学分析表明，组成的次要化合物不同的四个血桐物种，虽然有许多化合物是共同的。
Macaranga myrmecophytes harbor species-specific Crematogaster ants that defend host trees from herbivores. We examined ant aggressive behaviors when artificially damaged leaf pieces from another tree were offered to four sympatric species of obligate Macaranga myrmecophytes. The ants showed aggressive behavior in response to leaf pieces regardless of the leaf species; however, aggressiveness was higher when conspecific leaf pieces were offered than when nonhost species were offered. Thus, ants can recognize leaf damage and distinguish among damaged leaf species. Chemical analyses of volatile compounds emitted from damaged leaves that may induce ant defense showed that the composition of the minor compounds differed among the four Macaranga species, although there were many compounds in common.
