A review of the literature on transmission studies of nucleopolyhedroviruses showed that low levels of viral infection were common among studies of pupae of insects but rarer in adults. Virus could be transmitted from parent to progeny and could be found in caterpillars reared from surface-decontaminated eggs. Persistent low levels of infection were observed in many of the studies considered. These could contribute to the persistence of virus in low-density populations, but the dominant source of virus among generations is probably through environmental contamination.
对核多角体病毒传播研究的文献综述表明，在昆虫蛹的研究中，低水平的病毒感染很常见，但在成虫中则较为罕见。病毒可以从亲代传播到子代，并且可以在经表面消毒的卵孵化出的毛虫中发现。在所考虑的许多研究中都观察到了持续的低水平感染。这些可能有助于病毒在低密度种群中的持续存在，但各代之间病毒的主要来源可能是环境污染。
