Sex determination in bees. XXX. Effects of juvenile hormones on the development of tergal glands in Melipona
Ana Maria Bonetti; Carminda Da Cruz-Landim; Warwick Estevam Kerr
Worker larvae of Melipona rufiventris, M. quadrifasciata and M. compressipes were treated topically with juvenile hormone (JH) during the cocoon-spinning phase. Examination of the tergites of the queens obtained following JH application showed induced differentiation into adults with full female (queen) traits. Melipona workers had tergal glands only in tergite II, whereas natural and JH-induced queens had tergal glands in tergite II plus additional glands in at least one other of tergites III to VII.
