日本农林省林业试验场近30年来连续开展了利用微生物病原防治害虫的研究。这里特别介绍一下应用病毒防治森林害虫的研究成果。所谓昆虫病毒群,可以分为以下各类: 1.在被侵染的组织细胞内形成多角体型的包涵体: 1)形成于细胞核内,病毒为棒状(Bor-relinavirus)。2)主要形成于中肠细胞质中,病毒为球状(正20面体)(Smithiavirus)〔注:虽说“主要形成于中肠细胞质中”,但也有报告说可在核中看到大形少数的多角体。〕3)形成于脂肪体细胞质内,病毒为卵形(Vagoiavirus)。〔注:只在最近报告中提到在金龟子幼虫中发现,在日本尚未见到这一类群的报道。〕2.形成颗粒状包涵体,病毒为棒状(Be-rgoldiavirus)。3.不形成包涵体,病毒为球形(正20面体等)(Moratorvirus) 昆虫病毒的分类,尚未建立体系。
Japan’s Agriculture, Forestry and Forestry Experimental Site nearly 30 years to carry out the use of microbial pathogens to control pests. Here to introduce the application of virus prevention and control forest pests research results. The so-called insect virus group can be divided into the following categories: 1. In the infected tissue cells to form polyhedron-shaped inclusion bodies: 1) formed in the nucleus, the virus is a bar-shaped (Bor-relinavirus). 2) is mainly formed in the cytoplasm of the midgut, and the virus is globular (Smithiavirus). [Note: Although “mainly formed in the cytoplasm of the midgut,” it is also reported that large and small polygons can be seen in the nucleus body. 〕 3) formed in the fat cytoplasm, the virus is oval (Vagoiavirus). [Note: Only recent reports mention the discovery in beetle larvae, which have not yet been reported in Japan. 〕 2. Formation of granular inclusion bodies, the virus is a stick (Be-rgoldiavirus). 3. Inclusion body is not formed, the virus is spherical (positive 20 body, etc.) (Moratorvirus) insect virus classification, has not yet established a system.
