“…This discovery was brought on mostly by studies on the male antennae, functionally related with mating behavior (Dahms 1984, Bin andVinson 1986). Later, antennal glands were also described from several families of Hymenoptera, including Terebrantia (Bin et al 1999b, Isidoro and Bin 1995, Isidoro et al 1996, 1999, Battaglia et al 2002 and Aculeata (Isidoro et al 2000, 2003, 2006, as well as from other insect orders (Bartlet et al 1994, Weis et al 1999, Giglio et al 2005, with different biological significance. In some groups of egg parasitoids, antennal glands can be associated with both males and females specialized antennomeres, as well as closely associated with peculiar sensory structures.…”
