雄蚕杂交种的饲养标准技术研究 3.不同饲育技术标准对雄蚕发育及产茧量的影响

Studies on the Standard Techniques of Rearing male Silkworm Hybrid 3 The Effect of Different Rearing Techniques on the Male Silkworm Development and Cocoon Production

对夏华×平8用雄蚕饲育技术标准和常规品种二回育饲育技术标准做了对比饲养试验 ,调查其发育情况、龄期经过、稚蚕绝食生命时数和饥饿就眠率、眠蚕体重、蚕茧产质量等 ,结果雄蚕二回育技术标准能较好地控制日眠 ,从稚蚕绝食生命时数、饥饿就眠率及蚕茧产质量等综合分析看 ,雄蚕饲养标准更适合雄蚕的生理特点 ,更能发挥雄蚕品种的优良性状 ,可作为专养雄蚕的配套技术在生产上推广应用。

The comparison rearing experiment was carried out by rearing male silkworm variety Xiahua×Pin 8 with the male silkworm rearing standard techniques and the standard techniques of two feedings a day for practical varieties.Investigations on the silkworm development,larval duration,young larval living period after fast,hanger molting rate,body weight of molting silkworm and cocoon quality and so on were carried out,results showed that rearing technique of two feedings a day could control the molting better,but for the indexes of young larval living period after fast,hanger molting rate and cocoon quality,rearing technical standards for male silkworm were more suitable to the male silkworm's physiology characters.It could be used as the appropriate techniques for only male silkworm rearing extension.
