在人工条件下，幼体蜈蚣的生长同曲线呈两段性，前慢后快；体长与体重的关系曲线也呈两段性。群养时每次摄食量约为总体重的１／３凰单独饲养时是群养的３倍左右。不同食物对幼体蜈蚣生长的影响不同。食物转化率前期为１６．４２％，后期为２８．２３％。食物消耗与生长关系的回归系数ｂ＝０．３０７６．取食后体重首日下降最快，至第８天趋向恒定。５０条左右群养时成活率最高。
Under artificial conditions, the growth of the juvenile larvae is two-fold with the curve, before the slow and fast; the curve of the body length and weight is also two-stage. In the group feeding time, about 1/3 of the total weight of each food intake is about 3 times that of the group raising when it is raised separately. Different foods have different effects on the growth of larvae. The food conversion rate was 16.42% in the earlier period and 28.23% in the latter period. Regression coefficient of food consumption and growth relationship b=0.3076. After eating, body weight dropped the fastest on the first day and reached a constant on the 8th day. The survival rate is the highest when 50 or so groups are raised.
