【摘要】 １９７９年从舍蝇（Ｍｕｓｃａｖｉｃｉｎａ）幼虫中分离出一株能够形成伴孢晶体的芽孢杆菌７９００７。该菌具有苏云金杆菌天门变种（７２１６）的典型特征。血清型属Ｈ＿（３ａ－３ｂ），但培养特征，生化特征与知的Ｈ＿（３ａ－３ｂ）的戈尔斯德变种（ＨＤ－１）、天门变种（７２１６）略有不同，特别是对棉铃虫的毒力大大高于巳知的菌株，预示着将成为我国防治棉铃虫的一株高效菌。更多还原

【Abstract】 A parasporal crystal forming bacillus“79007”,was isolated from dead larvaof Musca vicina in 1979.This bacillus has the typical characteristics of Bacillus thuringi- ensis var. tianmentis（7216）.Its serotype belong to H_3a-3b, but it is distinguished fromstrain HD-1 and 7216 in cultural characteristics and biochemical reactions.The results showed strain 79007 is more high toxicity against cotton bollworm thanknown strain. This forecast that it is more cffective in the control of cotton bollworm thanany other strain commonly used in this country.更多还原
