| 摘 要： | 家蚕幼虫的生长曲线普遍呈Ｓ型，但因品种，性别，饲育条件和饲料的不同而呈多样性变化。作者采用目前可塑性较强、准确性较高的Ｒｉｃｈａｒｄｓ方程来描述家蚕５龄幼虫的体重增长情况，并建立了家蚕５龄幼虫及５龄不同性别幼虫的Ｒｉｃｈａｒｄｓ生长模型。

| Abstract: | The growth process of the silkworm can be illustrated with sigmoid form curves which vary according to the races ,the sex, the breeding condition ,the diet and other factors.The groth models of the 5th instar larvae of Bombyx mori were established by using Richards equation in the paper . |
