ABSTRACT
The efficacy of a biologic larvicidal preparation BLP was under study; the insecticide was prepared on the basis of a new strain of B. thuringiensis var. israilensis H-14, isolated from natural material, and its activity to Ae. caspiens, C. pipiens, An. hyrcanus larvae was examined. The minimal effective dose of BLP used for the treatment of various water bodies is 0.5 kg per 10,000 m2.
