The parasitoid wasp parasitizes the aphid , which is obligatorily attended by several species of ants of genus . Subgenus or ants use different defense strategies to protect the aphids that they attend (, shelter building; , aggressive attack). We performed molecular phylogenetic analysis based on partial mitochondrial DNA sequences of and found that the parasitoid wasp consists of two highly differentiated genetic lineages. Although these two lineages distributed sympatrically, one tends to parasitize aphids attended by ants of subgenus , and the other parasitizes aphids attended by ants of subgenus . The two lineages of appear to exhibit different oviposition behaviors adapted to the different aphid-protection strategies of the two ant subgenera.
这种寄生蜂寄生于蚜虫，而蚜虫会受到该属几种蚂蚁的必然照料。亚属或亚属的蚂蚁会采用不同的防御策略来保护它们照料的蚜虫（，建造庇护所；，攻击性攻击）。我们基于的部分线粒体DNA序列进行了分子系统发育分析，发现这种寄生蜂由两个高度分化的遗传谱系组成。尽管这两个谱系同域分布，但一个谱系倾向于寄生于亚属蚂蚁照料的蚜虫，另一个则寄生于亚属蚂蚁照料的蚜虫。的两个谱系似乎表现出不同的产卵行为，以适应两个蚂蚁亚属不同的蚜虫保护策略。
