Abstract

Juvenile hormone (JH) is the principal endocrine regulator of ovarian maturation in most insects. JH stimulates the fat body to synthesize vitellogenic proteins that are transported and deposited in the yolk of maturing oocytes. Neurohormones also affect vitellogenesis but their action is less well defined. In the tropical cockroach, Blaberus discoidalis, JH was essential for ovarian maturation, but the administration of corpora cardiaca (CC) extracts as a neuroendocrine source enhanced the amount of protein deposited in the ovaries in response to JH (Keeley and McKercher, 1985). The present investigations examined the interactions between JH and neurohormones as regulators of fat body protein synthesis and ovarian maturation in B. discoidalis.
