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.

火腹蚁和马卡兰加植物之间的亚洲蚂蚁-植物关联具有高度的物种特异性，蚂蚁的分子系统发育与植物系统发育平行，反映了共种历史。对九种共存 Macaranga 物种的叶子损害和天敌动物群的种间比较表明，这些植物的非生物（化学/结构）防御类型不同。尽管化学/结构防御存在这些差异，但蚂蚁定居的植物通常能够很好地抵御大多数种类的敌人。这与蚂蚁物种防御行为的差异一起表明，个别宿主特定的蚂蚁互利共生体非常适合阻止特定的敌人，这可能会克服宿主植物的化学/结构防御。
