Conditions for bioincapsulation of crystal-forming strain Brevibacillus laterosporus LAT 006 spores and crystals by using Tetrahymena pyriformis and Entamoeba moshkovskii Protozoa have been developed. Increase in the larvicidal activity of the incapsulated bacteria was demonstrated. Fractions of pure spores and crystals and intact spore-crystal preparation of LAT 006 were shown not to have toxic effect on the protozoa cells.
