Biological agents of control of the number of the blood-pressing cats (diptera: simuliidae) in Waterways of the Belarusian lawner

Abstract

The paper deals with the parasites and predators of blackflies in water-currents of the Belarusian Lakeland. It is described the biological activity of collection strains of Bacillus thuringiensis and also an entomopathogenic fungus Beauveria bassiana on Wilhelmia equina larvae of the third age in a comparative aspect. It was shown that the parasites of the preimaginal stages of blackflies are microsporidia, mermitida and fungi. The data resulting from the study suggest the possibility of using B. thuringiensis studied strains to population control of blood-sucking insects in particular of the family Simuliidae.
