优食一号小蚕颗粒人工饲料育的试养初探

2015年春季,在河南省蚕业科学研究院云阳试验基地内,进行了优食一号一至二龄颗粒人工饲料饲育、三至五龄桑叶育的养蚕试验,以探索颗粒人工饲料的养蚕条件和实用技术。结果显示:优食一号一至二龄颗粒饲料育的产茧量能够达到全龄桑叶育水平,蚕茧质量接近全龄桑叶育水平,养蚕工效比桑叶育分别提高5倍左右。

Preliminary Report on Rearing Youshi 1 Young Silkworm with Pellet Artificial Diet

In the spring of 2015 ,a silkworm rearing experiment was carried out within Yunyang Experiment Base ,Henan Provincial Sericulture Institute ,involving Youshi 1 silkworm at 1-2 instars fed with pellet artificial diet and those at 3-5 instars fed with mulberry leaf .The purpose was to explore the conditions for rearing the silkworm with pellet artificial diet and the practical technology .The results show that Youshi 1 silkworm at 1 -2 instars fed with pellet artificial diet can yield cocoons on a level with those fed with mulberry leaf at full instars produce ,and their cocoon quality is close to the level of those fed with mulberry leaf at full instars .It's proved that the pellet artificial diet can improve silkworm rea‐ring efficiency by about 5 times than mulberry leaf does .
