title: Interactive effects of 1-octen-3-ol and carbon dioxide on mosquito (Diptera: Culicidae) surveillance and control.
abstract: Responses of natural populations of biting Diptera were studied at Everglades National Park, Fla., to three levels (0, 3.0, and 41.1 mg/h) of 1-octen-3-ol (octenol), four levels (0, 20, 200, and 2,000 ml/min) of carbon dioxide (CO2), and their combinations. Catches of mosquitoes (Aedes taeniorhynchus (Wiedemann), Culex [Melanoconion]) spp., Cx. nigripalpus Theobald, and Wyeomyia spp.) and one tabanid (Diachlorus ferrugatus (F.)) were affected significantly by CO2 and octenol. Significantly greater numbers of all taxa were collected as the level of CO2 was increased. The 3.0-mg/h release rate of octenol alone resulted in increased trap catches relative to no bait for all taxa except Cx. (Melanoconion) spp., whereas the 41.1-mg/h release rate alone generally reduced trap catches relative to either no bait or 3.0 mg/h octenol. The effect of CO2 and octenol was additive for Cx. (Melanoconion) spp. and D. ferrugatus and synergistic for Ae. taeniorhynchus. Six octenol-supplemented CO2 treatments produced mixed results for Cx. nigripalpus.
