我所在1973年通过采集、分离和筛选,选育出一株新杀虫菌,经实验测定,已初步证明这个新杀虫菌对防治棉铃虫、斜纹夜蛾、稻纵卷叶螟、三化螟等6种害虫有较好的杀虫效果。该菌在1974年经中国科学院微生物研究所鉴定,为绿色穗霉(Spicara pracina Maulblane)。现将绿色穗霉的筛选和应用情况分述如下: I was in 1973 through the collection, separation and screening, breeding a new strain of insecticides, the experimental determination, it has been initially proved that the new insecticide against cotton bollworm, Spodoptera litura, rice leaf roller, three chemical Borer 6 kinds of pests have better insecticidal effect. The bacteria in 1974 by the Chinese Academy of Sciences Institute of Microbiology identified as spikes (Spicara pracina Maulblane). Now green spike screening and application of the situation are as follows:
