摘　　要：三眠蚕末龄与四眠蚕末龄的生长规律比较相似,三眠蚕末龄与四眠蚕末龄体重饲料效率变化有相似倾向;四眠蚕的生长程度、茧期成绩和卵量比三眠蚕高,但三眠蚕的体重、全茧量和卵量的饲料效率比四眠蚕高。The final instar larvae of trimolters and tetramolters of silkworm appeared similar in their growth and body weight and showed similar feed efficiency. However, the growth of the tetramolters, their performance in the cocooning period and amount of ages were higher than those of their trimolting counterparts while the body weight, cocoon weight and feed efficiency of the trimolters were higher that those of the tetramolters.
