S. ². Denisova, T. B. Aretynska, V. O. Trokoz
In the article the results of study of influence of preparation of gumiñ nature Riverm come into a question on the biological indexes of organism of oak silkworm (Antheraea pernyi Guer.). Useful insects at feeding different forage plants show different reaction on introduction of the studied preparation. Riverm can serve as effective forage addition for the improvement of nourishing qualities of untraditional for silkworm forage - leaves of birch. On the whole, the use of leaves of oak and birch, treated preparation of riverm at rearing of oak silkworm caterpillars abbreviates the terms of their development on 6 days, promotes viability on 10-15 %, brings to growth zoo masses over of insects and instrumental in the increase of fecundity of imago. Under act of treatment of forage by preparation riverm efficiency of transformation of forage in the deadweight of body of caterpillars grows on 8-10 % by comparison to control. It brings to the increase the masses over of cocoons and silk content.
