A comparative study was conducted to test the efficiency of Centers for Disease Control and Prevention (CDC) light traps baited with either dry ice or carbon dioxide (CO2) produced from one of three different sources in collecting mosquitoes (Diptera: Culicidae) in Thailand. Treatments consisted of dry ice pellets, CO2 gas produced from one of three prototype CO2 generator systems (TDA, CUBE, Moustiq-Air Med-e-Cell - MEC), and a CDC light trap without a CO2 source. The best performing prototype from Thailand was then tested in collecting sand flies (Diptera: Psychodidae: Phlebotominae) in Greece. A total of 12,798 mosquitoes and 8,329 sand flies were sampled during the experimentation. The most prevalent mosquito species collected in Thailand were: Culex vishnui Theobald > Anopheles minimus Theobald > Culex tritaeniorhynchus Giles > Anopheles sawadwongporni Rattanarithikul & Green. By far the most prevalent sand fly species collected in Thessaloniki was Phlebotomus perfiliewi Parrot followed by Phlebotomus tobbi Adler and Theodor and Phlebotomus simici Nitzulescu. In general, the TDA treatment was the only treatment with no significant difference from the dry ice-treatment in mean trap catches. Although dry ice-baited traps caught higher numbers of mosquitoes and sand flies than the TDA-baited traps, there was no difference in the number of species collected. Results indicate that the traps baited with the TDA CO2 generator were as attractive as traps supplied with dry ice and, therefore, the TDA CO2 generator is a suitable alternative to dry ice as a source of carbon dioxide for use with adult mosquito and sand fly traps.
开展了一项比较研究，以测试美国疾病控制与预防中心（CDC）的诱蚊灯在泰国收集蚊子（双翅目：蚊科）时的效率，这些诱蚊灯分别用干冰或由三种不同来源之一产生的二氧化碳（CO₂）作为诱饵。实验处理包括干冰颗粒、由三种原型CO₂发生器系统（TDA、CUBE、Moustiq-Air Med-e-Cell - MEC）之一产生的CO₂气体，以及一个没有CO₂源的CDC诱蚊灯。然后在希腊测试了来自泰国表现最佳的原型，以收集白蛉（双翅目：蛾蠓科：白蛉亚科）。实验期间共采集了12798只蚊子和8329只白蛉。在泰国收集到的最常见蚊子种类为：致倦库蚊>微小按蚊>三带喙库蚊>萨氏按蚊。在塞萨洛尼基收集到的最常见白蛉种类是佩氏白蛉，其次是托氏白蛉和西氏白蛉。总体而言，TDA处理是唯一与干冰处理在平均诱捕量上无显著差异的处理。尽管用干冰作诱饵的诱蚊灯捕获的蚊子和白蛉数量比用TDA作诱饵的诱蚊灯多，但收集到的物种数量没有差异。结果表明，用TDA CO₂发生器作诱饵的诱蚊灯与用干冰的诱蚊灯一样具有吸引力，因此，TDA CO₂发生器作为成年蚊子和白蛉诱捕器的二氧化碳来源，是干冰的合适替代品。
