昆虫在自然界由于病原微生物(细菌,病毒、真菌,线虫等)的侵染而引起种群的致病或死亡,是屡见不鲜的。我国地域广阔,昆虫种类繁多,昆虫病原相当丰富。但是过去对于有用病原的收集和利用开展的还不够充分。 昆虫的病毒病原的收集不仅在病毒研究上有一定重要意义,而且也是微生物防除害虫中较有前途的材料。昆虫病毒中以核型多角体病毒与颗粒体病毒致病的实例较多,同时在应用上意义也较大。
It is not uncommon for insects to cause disease or death in populations due to the infestation of pathogenic microorganisms (bacteria, viruses, fungi, nematodes, etc.) in nature. China has a vast territory, a wide range of insects, and abundant insect pathogens. However, in the past, insufficient collection and utilization of useful pathogens were carried out. Insect virus pathogen collection not only in the study of the virus has some significance, but also the more promising pest control microorganisms in the material. Insect virus to nuclear polyhedrosis virus and granulosis virus pathogenic cases more, while the significance of the larger applications.
