笔者有幸以日本农林水产省“为确立生物学方法防治病虫害新技术的综合研究”国外考察的机会,于1984年9月访问了在研究微生物防治害虫方面居领先地位的美国。时间虽短,却也访问了四个研究机构,其中三个在加利福尼亚州,一个在密苏里州。选定这些机构是因为笔者的研究领域是天敌病毒利用,故而并不广泛收集美国微生物防治研究的全部近况。以下就这些机构的研究情况作一介绍。
The author was fortunate enough to visit the United States in September 1984 in a leading position in the study of microbial control of pests with the opportunity of an overseas study conducted by Japan’s Ministry of Agriculture, Forestry and Fisheries on “a comprehensive study to establish a new approach to biological control of pests and diseases”. Although time was short, four research institutes were visited, three in California and one in Missouri. These institutions were selected because the author’s field of research is the use of natural enemy viruses and therefore do not extensively collect all the current status of research on microbial control in the United States. The following briefing on the research of these institutions.
