摘要
为了优化原蚕饲养的营养条件,提高蚕种繁育质量,对几个实用桑品种饲养的原蚕饲育成绩进行了初步调查与分析。用几个实用桑品种分别饲养原蚕,其发育经过及幼虫生命率、虫蛹统一生命率等无明显差异;但死笼率有育151号较高,新一之较低的倾向。综合原蚕饲养的茧质和卵质成绩初步认为,春期原蚕繁育用桑适宜选择的桑品种依次为育71-1、湖桑32号、育151号、新一之濑;秋期原蚕繁育用桑适宜选择的桑品种依次为新一之、育71-1、湖桑32号。
In order optimize nutrition conditions for the parent silkworm rearing and raise the quality of silkworm eggs, the rearing results of parent silkworm fed on various commercial mulberry races were investigated and analyzed. Reared with the several tested mulberry races, the duration of developmental stage, survival rate of larvae and survival ratio of pupae and larvae of the parent silkworms didn＇t differ greatly while the rate of dead silkworm cocoon of Yu 151 was shightly high and that of Neo-lchinose was low. Based on the comprehensive survey on the cocoon quality and eggs quality of pareat silkworm, it is concluded preliminary that the mulberry races for parent silkworm rearing are Yu 71-1, Husang 32, Yu 151 and Neo-lchinose in spring season and Neolchinose, Yu 71-1 and Husang 32 in autumn season respectively.
