Juvenile hormone production and accessory reproductive gland development during sexual maturation of male Blattella germanica (L.) (Dictyoptera, Blattellidae)

摘要

1. A study of the release of juvenile hormone (JH) by in vitro-incubated corpora allata (CA) and on the development of the accessory reproductive glands (ARG) during sexual maturation of male Blattella germanica has been performed. 2. JH release rates are comparable with those observed in previtellogenic females. 3. The ARG undergo a progressive increase in size and protein content during sexual maturation. 4. After CA removal, ARG protein accumulation is reduced (by 50%) in comparison with controls, and administration of exogenous JH restores normal development. 5. The involvement of JH in ARG growth is discussed. © 1992.
