Some laboratory studies revealed that predators can readily attack and consume virus-infected prey with no detrimental effects on their biological parameters. Most tested predacious species did not discriminate between healthy and virus-infected prey. In addition, such predators were found to excrete detectable amounts of polyhedral inclusion bodies for few days that might infect healthy prey. Field studies demonstrated that the population densities and dispersal of the predators were not affected in fields sprayed with entomopathogenic virus formulations. Some laboratory studies stated that egg and larval parasitoids did not discriminate between healthy and virus surface-contaminated or virus-infected hosts. However, some parasitoids did not lay or laid few eggs in virus-infected hosts. Parasitoid adults that laid eggs in virus-infected host larvae could transmit the virus to healthy hosts through the ovipositor. Also, adult parasitoids emerged from virus-infected hosts transmitted the virus to healthy hosts whereas other parasitoids did not transmit the virus.

杆状病毒和食虫昆虫之间的相互作用

一些实验室研究表明，捕食者可以容易地攻击和食用受病毒感染的猎物，而对其生物学参数没有有害影响。大多数经过测试的珍贵物种并未区分健康和病毒感染的猎物。此外，发现这种天敌会在几天内排泄出可检测量的多面体包涵体，从而感染健康的猎物。野外研究表明，在喷洒昆虫病原性病毒制剂的田地中，捕食者的种群密度和扩散没有受到影响。一些实验室研究表明，卵和幼虫的类寄生虫不能区分健康的和病毒表面污染的或感染病毒的宿主。但是，有些寄生虫没有在病毒感染的宿主中产卵或很少产卵。在受病毒感染的宿主幼虫中产卵的拟寄生虫成虫可以通过产卵器将病毒传播给健康宿主。同样，从被病毒感染的宿主中出来的成年寄生虫会将病毒传播给健康宿主，而其他寄生虫则不会传播病毒。
