Abstract

The purpose. To study influence of feeding with specimen KAS-81 and its components (extracts from Artemísia absínthium and gemmas of Pínus sylvéstris) on bee colony with natural invasion background. Methods. Experiments in nature environment were spent on nucleus colonies with natural invasion environment, equal on force which occupied on the average 3–4 frames in the early spring. Results. Effect of optimum densities of BAS of vegetable origin on force of colonies and extent of their infestation by spores of Nosema sp. is determined. Conclusions. Improving effect of specimen KAS-81 and its components is determined. It manifested itself in faster (for 12 – 15 days) clearing of experimental colonies from spores of Nosema sp. in comparison with control ones (bees without treatment). Specimen KAS-81 has appeared more effective than extract from its components.
