Polyfunctional properties of the Bacillus thuringiensis var. Thuringiensis industrial strain 800/15

Crop losses caused by pests can reach 40-50 % and even more. Application of biological methods for regulation of the harmful species is promising and providing ecological safety. Biological preparations based on the living cultures of microorganisms and their metabolites meet these requirements. Currently, the crystal-forming bacterium Bacillus thuringiensis is considered to be the most important species for production of biological insecticides, since this bacterium exhibits high specificity in relation to the target pathogens, safety for humans and the environment. At ARRIAM, the biological preparation based on the Bacillus thuringiensis var. thuringiensis ( Bt H1) 800/15 strain was developed. The strain was isolated from larvae of the Colorado potato beetle ( Leptinotarsa deсemlineаta Say.) in the Leningrad region, studied for culture-morphological, biochemical and serological properties and identified according to the classification of De Barjac and Bonnefoi...
