Example text

Both methoprene and ecdysone are capable of inducing the synthesis of YPs in the isolated abdomens of female Drosophila, but only those abdomens receiving methoprene accumulated yolk in the oocytes (Postlethwait and Handler, 1979). , 1983), and transplanting vitellogenic oocytes to JH-deficient hosts caused the oocytes to degenerate (Wilson, 1982). These observations confirm that JH is required throughout vitellogenesis. Diapausing Drosophila exhibit low titres of JH, and, although YP is present in the haemolymph, it fails to enter the follicles.

The fat body in these flies did not appear to respond to JH by synthesizing YP. Taken together, these facts conform to the view that JH prepares the fat body to respond to ecdysone from the ovaries, as has been more clearly and crisply demonstrated for mosquitoes. By allatectomizing adult females of the blowfly, Phormia reginu, and treating with methoprene at various times after a liver meal, Qin et ul. (1995) have further explored 24 G. R. W Y A T AND K. G. DAVEY the role of JH in the control of vitellogenesis.

The biological significance of this striking regulatory mechanism is unknown. 1 Ovaries In some insects, all of the eggs are produced in the pupal stage, but in many species at least some of the egg production occurs in the adult. There are several phases in the production of an egg. The oogonia multiply by mitosis, and in meroistic ovaries some of the oogonia become specialized as nurse cells (trophocytes). In the telotrophic ovary, the nurse cells may retain their ability to divide by mitosis after the oocytes have differentiated.
