Response of biting midges (Diptera: Ceratopogonidae) to carbon dioxide, octenol, and light in southeastern Queensland, Australia.
The effect of 1-octen-3-ol (octenol) on catches of estuarine biting midges in encephalitis vector surveillance (EVS) traps was examined in southeastern Queensland. Octenol by itself was not attractive but appeared to act as a synergist with CO2 to increase catches of most species. For four of six species tested, a medium (about 6 mg/h) release rate of octenol captured the most individuals. Addition of light also increased the catch size of most species. Octenol in combination with CO2 could be used to enhance biting midge catch size, improving the sensitivity of surveillance for midges and the pathogens they vector.
