【Abstract】 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.更多还原
