Bacillus thuringiensis israelensis - Wikipedia
网页Bacillus thuringiensis serotype israelensis (Bti) is a group of bacteria used as biological control agents for larvae stages of certain dipterans. Bti produces toxins which are effective in killing various species of mosquitoes, fungus gnats, and blackflies, while having almost no effect on other organisms.
Bacillus Thuringiensis Israelensis - an overview - ScienceDirect
网页Bacillus thuringiensis israelensis was registered for use in 1981 (Tanada and Kaya, 1993) and was rapidly developed in the 1990s into products used for mosquito control in many countries. Bacillus thuringiensis israelensis became important in attempts in the 1980s and 1990s to control black flies, which serve as a vector for the nematode that ...

Discovery of Bacillus thuringiensis israelensis | SpringerLink
网页Abstract. For the past four decades humans have been almost completely dependent upon synthetic organic insecticides. However, the very properties that made these chemicals useful—long residual action and toxicity for a wide spectrum of organisms—have brought about serious environmental problems. The emergence and spread of insecticide ...
