| 摘 要： | 在家蚕卵进入滞育后,用30 Gy吸收剂量的60Coγ射线对带有家蚕微粒子病原的家蚕种进行放射治疗,在3个中试点3年的小面积防治试验中均取得了较好的防治效果,全茧量平均增加7.70%,茧层量平均增加16.20%,茧层率平均增加7.99%,但3龄起蚕绝食生命时数平均下降4.5 h,死蛹率平均增加2.15%,全龄经过平均延长13 h,1日孵化率与2日孵化率均极显著低于对照区,表明蚕卵经放射治疗后家蚕体质已有所下降。

| Abstract: | After silkworm eggs enter the diapause period,radiation therapy with 60Coγ-ray at 30 Gy absorbed dose against Nosema bombycis disease in silkworm eggs was conducted for 3 years at three spots,and good effects have gotten as follows: cocoon weight increased by an average of 7.70 percent,cocoon shell weight increased by an average of 16.20%,cocoon shell percentage increased by an average of 7.99 percent.But since the 3rd instar,the longevity of fasted silkworm decreased by an average of 4.5 hours,the mortality of pupae increased by an average of 2.15 percent,and the average duration of whole larvae stage increased by 13 hours,and the hatchability of 1-day-old and 2-day-old eggs was all lower than that of the control.These results proved that after radiation therapy the silkworm eggs have shown some decline in their physical condition. |
