应用60Co-γ射线辐射治疗家蚕微粒子病研究
Studies on the Control of Pebrine Using 60Co-γrRay Irradiation
摘要
Abstract
[Objective] The research aimed to discuss the new method for preventing and controlling the pebrine. [Method] 60Co-γ ray was used to treat Nosema bombycis, infected silkworm larvae, pupae and eggs with pebrine. The differences of silkworm and N. bombycis under 60Co-γ ray irradiation and the control effects on pebrine were studied. [Result] 20 - 160 Gy 60Co-γ ray irradiation could not kill N. bombycis and /V. bombycis of infected silkworm. The larva weight of infected silkworm decreased with the increase the irradiation dose. The mortality rate of infected silkworm treated by 80 Gy irradiation had an obvious increasing trend. With the increase of radiation dose, the hatching rate of the eggs under radiation treatment decreased and the virus rate of hatched silkworm decreased to certain degree, and the total virus rate of hatched silkworm and unhatched silkworm decreased. Little dose irradiation of 20 -160 Gy could remove N. bombycis in the silkworm chrysalis. With the increase of radiation dose, the silkworm pupa emergence rate, virus rate of mother moths, virus rate of eggs and the copulation ability of male moths gradually decreased. The emergence rate of pupa treated by 20 Gy irradiation was higher than that of control and other treatments. [Conclusion] Low-dose 60Co-γ ray irradiation had certain detoxification effects on the silkworm eggs.关键词
