Mutated microorganism with toxin inclusion for pest control.

摘要

Biologically pure mutants of Bacillus cereus sub-species israelensis (also called Bacillus thuringiensis sub. sp. israelensis) which are substantially non-spore-forming but which are capable of forming inclusion bodies toxic to Diptera larvae are described. A spore-free insecticide based on these inclusion bodies as well as the method of producing same are disclosed.
