在实验室用东部地下白蚁（Reticulitermes flavipes（Kollar））进行的致病性试验中，冠状虫霉（Entomophthora coronataKevorkian）在接种后84小时产生97%的死亡率。在对白蚁的毒力试验中，两株E.冠状动脉无显著性差异。组织学检查表明，芽管渗透的珠被导致死亡前的白蚁，显然是不限于一个特定的网站。在消化道中，E.冠状动脉穿透食道壁，但不穿透作物、中肠和后肠。入侵菌丝首先攻击脂肪体和肌肉组织，然后迅速破坏剩余的组织，早在接种后32小时。
In laboratory pathogenicity tests with the eastern subterranean termite,Reticulitermes flavipes(Kollar),Entomophthora coronataKevorkian produced a mortality of 97 percent 84 hours after inoculation.Entomophthora virulentaHall and Dunn was found to be nonpathogenic under similar conditions. In a virulence test against termites, two isolates ofE. coronatashowed no significant difference. Histological examination indicated that germ tube penetration of the integument resulted before death of the termite and apparently was not restricted to a particular site. In the digestive tract, germinating conidia ofE. coronatawere found penetrating the oesophageal wall but not the crop, midgut and hindgut. Invading hyphae first attacked the fat body and musculature and then rapidly destroyed the remaining tissue as early as 32 hours after inoculation.
