MUTANT OR VARIANT OF BACILLUS THURINGIENSIS, PREPARATION PROCESS THEREOF, PREPARATION PROCESS FOR DELTA-ENDOXINE WITH ITS HELP, INSECTICIDE PRODUCT ON THE BASIS OF DELTA-ENDOTOXINE AND CONTROLLING METHOD FOR THE PESTS WITH THIS PRODUCT

摘要

This invention relates to mutants or variants of Bacillus thuringiensis producing high amounts of active delta-endotoxins. The delta-endotoxins produced by the mutant or variant B. thuringiensis will have an activity directed towards the same pest insects as its parent B. thuringiensis delta-endotoxins, such as against lipidopterans (mutants from B. thuringiensis subsp. kurstaki or subsp. aizawai), dipterans (mutants from B. thuringiensis subsp. israelensis) or coleopterans (mutants from B. thuringiensis subsp. tenebrionis).
