Juvenile hormone (JH) is an insect hormone that is responsible for the control of a variety of physiological and developmental states. In termites, JH has long been considered to play an important role in caste differentiation, although the detailed mechanisms underlying the actions of the hormone are not well understood. In this study, we applied three types of precocenes, anti-JH agents that destroy the corpora allata (CA), to pseudergates (workers) of the damp-wood termite Hodotermopsis sjostedti, and evaluated the effects on the CA volume and JH titer after the treatments. Results showed degeneration of the CA at day 14 in the precocene-II-treated group, which was not observed in the control group. Conversely, no significant difference in the JH titer was apparent between precocene-II-treated groups and their corresponding controls. These results indicate that CA degeneration is not always correlated with a decrease inJH titer. Precocenes are thus not effective as anti-JH agents in the focal termite species. These findings indicate that simultaneous examination of JH titer and CA size are important considerations for evaluating the effects of anti-JH agents.
