Modifications de l'équipement endocrine et morphogenèse génitale chez l'embryon de Carausius

It has previously been shown that in Carausius the mechanisms ensuring normal, i.e. female, differentiation of the genital rudiment can be deflected towards male differentiation. A study of bicephalic monsters and microsurgical experiments show that the genital anlage is not affected by a lack or an excess of neurosecretory or allatal components. However, experiments show that the prothoracic glands (=ventral cephalic glands) play an important part in the development of the genital anlage.
