不同群种的地下白蚁(Reettermes sp.)暴露于球孢杆菌、绿僵菌或绿僵菌的整个培养物中。在不同的时间间隔后取出个体，将后肠内容物电镀到马铃薯葡萄糖琼脂上。活孢子在暴露后8小时内首次出现在后肠。从患病白蚁的后肠中分离到的真菌是健康白蚁的病原菌。组织学检查表明，金龟子绿僵菌对血腔的入侵完全是通过直接侵入被膜。死亡后24小时。球孢杆菌主要通过消化道入侵。白蚁死亡前12h。
Separate groups of subterranean termites (Reticulitermes sp.) were exposed to whole cultures of B. bassiana, G. virens or M. anisopliae. Individuals were removed after varying time intervals and hindgut contents were plated onto potato dextrose agar. Viable spores first appeared in the hindguts within 8 h of exposure. Fungi reisolated from the hindguts of diseased termites were pathogenic of healthy termites. Histological examination showed that invasion of the hemocoel by M. anisopliae occurred exclusively through direct invasion of the integument .apprx. 24 h after death. B. bassiana invaded primarily through the alimentary tract, .apprx. 12 h prior to termite death.
