| Popis: | The strain variation B-2-6 with a higher production of spores (3.93 × 109 КFU/ml in that variation vs 1.94 × 109 КFU/ml in the initial strain) and endotoxin (10.1 mcg/ml vs 4 mcg/ml respectively) was obtained by means of the ultraviolet irradiation of the В-2 strain Bacillus thuringiensis spores. Insecticidal activity of the obtained variation is characterized by the deaths of 64.3 % of the great brown twist Archips podana at the 3rd day and 97 % at the 10th day after the treatment, which is 20.4 % higher than B-2 strain activity. Possibility of the obtained variation implementation for the natural plants protection against the leaf-eating insects is under discussion. |
