Nosematose injuries to queen bees progeny - worker bees - following gamma irradiation

A study is made of the effect of the queen bee exposure to Co60 gamma radiation of different doses on the resistance of the honeybees to nosematosis. The bioassay consists in a whole-body single irradiation of the queen bees at the GUBEH-800 gamma-irradiation plant with the dose rate 476 r/min (Co60). The scheme of the experiments is described. The investigations have demonstrated that under equal living conditions the bees of the same age incubated in the beehive exhibit different susceptibility to nosematosis. In the case of seven days old bees after the exposure of the queen bee to 1500 r dose the general nosematosis injury has dropped sharply as compared to the progeny of the bees produced prior to irradiation. The bees' organism at this age is actively resisting the disease and also compensating for the injured tissue functions caused by irradiation. The experiments have been conducted on determining the optimal radiation doses affecting the disease progress
