Studies have been conducted to assess the effectiveness of bioinsecticide preparation based on the sporocrystalline complex Bacillus thuringiensis and the nuclear polyedrosis virus. Before the preparation usage, a significant excess of the economic threshold of harmfulness for the investigated pest was noted on the experimental area of 1 ha. In the first survey of the site, Plutella xylostella caterpillar numbers on one plant varied within 5-6 caterpillars range when 62% of white cabbage plants were settled. After 3 treatments with an experimental preparation, the number of caterpillars decreased to 98 sp./100 plants and biological efficiency was 80.4%. Also, the effectiveness of the biopreparation in comparison with chemical insecticides was proved by single-factor dispersion analysis (Fobs.= 9.05; Fcrit.= 5.98).
