Twenty-four dacine fruit fly species were recorded in a lure trapping aurvey in Sri Lanka. The number of species attracted by a cue lure (CL) or methy eugenol (ME), and those that didn't respond to either but were recorded in a fruit collection survey, were 17, 7, and 6, respectively. These records and the distribution of responsiveness among dacine fruit flies of Sri Lanka according to the existung classification were investigated. The results showed that those that responded to ME were distributed in only one genus, Bactrocera (Bactrocera), while those that responded to CL were distributed widely across different genera and subgenera: Bactrocera (subgenera Afrodacus, Bactrocera, Zeugodacus, Javadacus, and Parazeugodacus), and Dacus (Callantra). The results were consistent with the general tendency of responsiveness among Dacini. The ratio of species that responded to CL and those that responded to ME was about 2.4: 1.
