Four treatments of feeding amount were made for the parents of the new silkworm hybrid race Xiafangand Qiubai for summer-autumn rearing at their 5th instar stage to investigate the performance of the lar-vae, cocoons and eggs. The results showed that the optimum feeding rate at the 5th instar stage was 59 kgmulberry leaves per gram of newly-hatched larvae, its performance indicators investigated in the study be-ing superior to those of any other treatment.
