一株对棉铃虫高效的苏云金杆菌
A HIGH TOXIC ISOLATE OF BACILLUS THURINGIENSIS AGAINST COTTON BOLLWORM
【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。
【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 H3a-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.
