The effect of diet water content on the growth, cocoon quality and food utilization of the silkworm was investigated. The body weight of mature larvae increased greatly as the water content increased, and the weight increase was mainly due to the increase of water content of larvae. The diet water content was less effective on the water content of pupae than on that of mature larvae. The water content of feces increased progressively as the fifth-instar larvae grew, especially in the larvae fed with diets having high contents of water. The suitable water content in the diet ranged from 60 to 65% for the cocoon quality, although it was found to be somewhat different between the 2 silkworm races used. On the basis of the above results, we tried to make a new type of artificial diet for the silkworm
