Summary

The endogenous titres of juvenile hormone III (JH III), and the in vitro rates of juvenile hormone biosynthesis by isolated corpora allata have been measured at intervals during the reproductive cycle of adult female Periplaneta americana. There was a close correlation between the rates of JH III biosynthesis and endogenous hormone titres. Only JH III was detected in whole body extracts, and hormone titres reached a peak (mean approximately 29 ng/g) at about the mid-point of the ootheca production cycle.
