Abstract:
In Myzus persicae wing dimorphism can be influenced before and after birth. Biogenic amines are involved in the regulation of wing dimorphism, and we have now used radio-labelled amines to study the possible relation between the endocrine system, the supposed role of juvenile hormone and biogenic amines. The data presented indicate that JH does not play a role in the action of messengers between the maternal body and the developing embryo. Our preliminary results suggest that a direct message is transmitted from the maternal brain to the embryo. Between 5 and 15 min after injecting a radiolabelled biogenic amine or its precursor into the haemolymph, labelled substances are present in the older embryos.
