摘要：

Juvenile hormone III biosynthesis by corpora allata of adult female Leucophaea maderae was measured by an in vitro radiochemical assay. In fed females, JH III synthesis increases more than 20‐fold after mating to a peak of 55 pmol/pair/h on day 9 and then rapidly declines. This increase in JH III synthesis concomitant with rapid oocyte growth in mated females is not observed in virgin females. The corpora allata from starved, virgin females appear to be inactive. The addition of 150 μM 2E,6E‐farnesol (a JH III precursor) to the incubation medium stimulates the corpora allata from starved, virgin females less than the corpora allata from starved, mated females. Both feeding and mating are necessary for the expression of a normal cycle of JH III synthesis in this cockroach. Copyright © 1990 Wiley‐Liss, Inc.
