我们从1978年开始研究利用光照解除柞蚕滞育制秋种的方法。几年来的试验和生产鉴定表明,在5、6月采茧后即以每天17—18小时的光周期照射柞蚕蛹茧的头部,经20—30天即能解除滞育而开始羽化,10—15天内的实用羽化率达到73.4—88.6%,每万粒种茧平均制出种卵9.5斤,普通孵化率达90%,达到生产上的实用价值,基本解决了我区柞 We started from 1978 to study the use of light to relieve tussah diapause of the autumn method. Tests and production appraisal over the past few years showed that in May and June after the cocoon that is 17-18 hours per day photoperiod irradiation tussah pupa cocoon head, after 20-30 days that can eliminate diapause and began to emerge, 10 -15 days of practical emergence rate reached 73.4-88.6%, per million seeds of cocoon average 9.5 pounds of eggs, the common hatch rate of 90%, to achieve the practical value of production, the basic solution to my area oak
