Yeast-generated CO₂ as a convenient source of carbon dioxide for adult mosquito sampling
Journal of the American Mosquito Control Association 20 (3), 261-264
Abstract: A new, convenient method was developed to supply CO₂ for mosquito sampling by using yeast, which converts sugar into CO₂ and ethyl alcohol. The system could, at average, generate 32.4 ml/min of CO₂ for at least 27 h. The total weight of the CO₂ generated was estimated to be 94 g. The efficacy of yeast-generated CO₂ as attractant for mosquitoes was significant, and the following 6 mosquito species were collected using yeast-generated CO₂ traps from July to September 2003 in a residential area of southern and northern Yokohama City, Japan: Aedes albopictus (Skuse), Armigeres subalbatus (Coquillett), Culex halifaxii Theobald, Cx. pipiens pallens Coquillett, Ochlerotatus japonicus (Theobald), and Tripteroides bambusa (Yamada). Besides mosquitoes, various other insects were collected in the trap. Species compositions of insects collected in yeast-generated CO₂ traps and dry-ice-baited traps were compared.
