Summary

Experiments were carried out to test the effects of relative humidity on prepupae and pupae of the Silkworm,Bombyx mori L., at 250 C. It was found that:

(1) duration of prepupal + pupal stages is the same at all relative humidities between 7 and 100%;

(2) mortality seems unaffected in all these humidity conditions;

(3) moths obtained in percentages between 55 and 100% R. H. have the same average wet weight; moths obtained under dryer conditions have a lower average weight (expressed in percentage of initial weights of prepupae);

(4) pupae extracted from their cocoons develop as quickly and as well as pupae in their cocoons.
