RESPONSES OF MOSQUITOS OF THE ANOPHELES FARAUTI COMPLEX TO 1-OCTEN-3-OL AND LIGHT IN COMBINATION WITH CARBON-DIOXIDE IN NORTHERN QUEENSLAND, AUSTRALIA

In northern Queensland, Australia, three experiments were conducted to determine the response of mosquitoes of the Anopheles farnuti complex to CDC traps baited with four attractant combinations: octenol + CO2 and light; octenol and light; CO2 and light; or CO2 and octenol withou t light. A CDC-modified updraft light-trap was also trialled, but did not significantly enhance collections of An.farauti sensu late. The co mbination of light, octenol and CO2 caught significantly more An.farau ti s.l. (both An.farauti No. 1 and No. 2 sibling species) when compare d to CO2 and light alone. Only small numbers of the An.farauti complex were captured when CDC traps were baited with octenol alone, i.e. no light or CO2.
