The surveillance and management of Dacini fruit fly pests are commonly split by gender: male trapping focuses on the dacine 'male-lures', whereas female lures based host-fruit volatiles. Although males several species have been reported to be attracted host volatiles, option using traps for has, date, ignored. Males cue-lure responsive Bactrocera tryoni (Froggatt) recorded as responding volatile blends, but it is not known how frequently this happens, if age-dependent, or strength response relative throughout year. Here, we conducted an olfactometer experiment test lifetime (weeks 1-15) B. odor tomato, a fly, compare catches wild tomato-based in field. started respond tomato they sexually matured (2 3 wk olds) thereafter showed consistent olfactory until advanced age (15 wk).
