寄生虫垂直传播的一个非常有效的机制是依赖于昆虫宿主的免疫反应。长须沙蛉的配子囊是通过血细胞介导的免疫反应被包裹起来的。A.由于这种囊施加的压力，chagasi被喷射到腺体的内腔中，粘在蛋壳上，随后被幼虫摄取。国际劳工组织实验抑制包囊反应的longipalpis，较少的附腺含有A.查加斯。
An exceptionally efficient mechanism for the vertical transmission of a parasitic gregarine is dependent on the insect host's immune response. Gametocysts ofAscogregarina chagasion the genital accessory glands of adult female sand flies (Lutzomyia longipalpis) become encapsulated through hemocyte-mediated immune reactions. Oocysts ofA. chagasi, ejected into the lumen of the glands owing to pressure exerted by this capsule, become glued to eggshells and are subsequently ingested by larvae. InL. longipalpiswith an experimentally suppressed encapsulation reaction, fewer accessory glands contained oocysts ofA. chagasi.
