The development of the metathoracic release site of Brindley's glands in adult Rhodnius prolixus has been investigated by treating larvae with juvenile hormone (JH) mimic at different times during the last instar and observing the extent of development in this region in the subsequently emerging insects. The results demonstrate a critical period of JH mimic sensitivity for release-site development comparable to that previously established for other adult morphological characteristics.

Intercellular Spaces

The follicular epithelium of vitellogenic oocytes from allatectomized females of Rhodnius fails to develop large intercellular spaces when exposed to juvenile hormone (JH) in vitro. This suggests that in the normal animal, the follicle cells require JH at two developmental stages. Differentiation of the cells in the presence of JH represents one requirement, and only those cells which have undergone this initial priming are fully competent to exhibit the second response, the development of intercellular spaces.

Two Factors ◽  
Humoral Action

The thoracic gland in Rhodnius breaks down and disappears within 48 hr. after the moult to the adult stage. Two factors are involved: (i) The gland suffers some change as the result of going through a moulting stage in the absence of the juvenile hormone. (ii) It must then be exposed to some humoral action at the time of the adult moult. The source and nature of the stimulus which operates at the time of the final ecdysis are not known. But when the gland has been exposed to these two changes it will rapidly break down even in an environment containing the juvenile hormone.
