Soldier differentiation and stationary molt of H. sjostedti. Soldier differentiation of the focal termite species can be artificially induced by JHA (pyriproxyfen) application. In this species, 6-7th instar larvae function as workers, i.e., pseudergates (PE). At 2 weeks after the JHA application, abdomens of pseudergates before the presoldier molt turn white because of gut purge (2wkPE). In 2 to 3 weeks after the application, the JHA-applied pseudergates molt into presoldiers (PS). Almost all pseudergates without artificial induction underwent stationary molt (SM).
