Summary

Mesothoracal ligations of young last instar larvae ofGalleria mellonella cause the abdominal ecdysteroid blood titer, as determined by radioimmunoassays, to decrease from 48 to 11–17 ng/ml. External application of 13 μg/g, the ecdysterone dose needed to stimulate normal wing growth, raises the titer to 360–1140 ng/ml for 2 days.
