摘　　要：雄蚕杂交种夏华×平8用三种蚕座密度和用桑量饲养 ,调查其发育情况、龄期经过、眠蚕体重、蚕茧产质量及其经济效益 ,结果不同饲育密度和不同用桑量对其生长发育和龄期经过无影响 ;从蚕茧产、质量及综合经济效益看 。The male silkworm hybrid, Xiahua × Pin8, was reared with three different rearing densities and different amount of leaves for feeding to investigate the situation of growth and development, duration of feeding period, the body weight of molting silkworm, the output and quality of cocoon and economic benefits. The result showed that the different rearing densities and the amount of leaves for feeding had no any influence on the larval development and duration, however, as far as the output and quality of cocoon and comprehensive economic benefits were concerned, the middle density and the amount of leaves for feeding designed by the experiment were best of all.
