The Asian ant-plant association between Crematogaster ants and Macaranga plants was highly species-specific, and the molecular phylogeny of the ants parallels the plant phylogeny reflecting the history of cospeciation. Interspecific comparison of leaf damage and enemy fauna of nine coexisting Macaranga species supported that the plants differ in their types of non-biotic ( chemical/structural ) defense. Despite these variations in chemical/structural defense, ant-colonized plants were generally well defended by ants against most kinds of enemies. This, together with the differences in defensive behavior of the ant species, suggests that the individual host-specific ant mutualists are well adapted to deter the specific enemies, which can potentially overcome the chemical/structural defense of the host plants.

crematogaster蚂蚁和麦卡兰加植物之间的亚洲蚂蚁植物关联是高度物种特异性的，蚂蚁的分子系统发育与植物的系统发育相似，反映了相应的历史。六种共存的麦卡兰加物种的叶子损伤和敌人动物群的种间比较支持植物在非益生元（化学/结构）防御的类型上有所不同。尽管在化学/结构防御方面存在这些变化，但蚂蚁殖民化的植物通常受到针对大多数敌人的辩护。这与蚂蚁物种的防御行为的差异一起表明，单个宿主特异性的蚂蚁共同主义者非常适合阻止特定的敌人，这些敌人可能有可能克服宿主植物的化学/结构防御。
