title: The effectiveness of light, 1-octen-3-ol, and carbon dioxide as attractants for anopheline mosquitoes in Madang Province, Papua New Guinea.
abstract: The effectiveness of light, 1-octen-3-ol (octenol), carbon dioxide (CO2) and a combination of CO2 and octenol were compared as mosquito attractants using encephalitis vector surveillance traps in 2 villages in Madang Province, Papua New Guinea (PNG). Five species were collected, Anopheles koliensis, Anopheles farauti 2, Anopheles farauti 4, Anopheles longirostris, and Anopheles bancroftii. Light alone was not attractive to any of these species, and the attractiveness of octenol alone, though greater than light, was less than that of CO2 or the CO2 + octenol combination. With An. longirostris, the addition of octenol to CO2 resulted in a statistically significant increase in trap numbers; however, for the other species, any increase was not significant, and with An. koliensis and An. bancroftii, trap numbers were actually reduced when the CO2 + octenol bait was used. In PNG, the use of octenol alone would be effective in attracting more anophelines than if light alone was used; however, octenol by itself was not as effective as CO2.
