Abstract
Allatectomy showed that Juvenile Hormone (JH) induced the accumulation of proteins in the accessory reproductive glands (ARG) of male Blattella germanica. During mating, the formation of the spermatophore and its transfer to the female was observed, and a selective depletion of most ARG proteins occurred in parallel, as shown by electrophoretic studies carried out at selected moments of the process. The synthetic activity of corpora allata incubated in vitro, measured at the same times, indicated that JH production is inhibited during the formation and transfer of the spermatophore. It is suggested that this inhibition may be necessary to start a new cycle of ARG maturation. © 1996 Wiley-Liss, Inc.
