Influence of biologically active agents of vegetable origin in comparison with antibiotics upon bees at nosematosis

Abstract

The purpose. To study possibility of improvement of bees at nosematosis by biologically active agents of vegetable origin in comparison with the most spread anti-nosematosis specimens on the basis of antibiotics. Methods. Research is carried out on summer generation of even-aged flight bees with artificial inoculation by Nosema sp. (5·104 spores for a bee). Investigated materials were fed on 11th and 18th day after the moment of infestation. Results. Influence is determined of specimen KAS-81 and its components, as well as Fumagilin and Nozemat upon dynamics of death of bees with nosematosis and level of their infestation by spores of Nosema sp. in laboratory conditions. Conclusions. Feeding with vegetable specimen KAS-81 and its components, and also specimens on the basis of antibiotics (Fumagilin and Nozemat) slow down death of bees infected by spores of Nosema sp. in comparison with control (septic bees were not treated up to the end of their natural death). The most effective among the probed matters has appeared specimen KAS-81.
