We set out no. 17 Trinidad traps baited with hamsters at a swamp in Tennessee, where recent eastern equine encephalomyelitis (EEE) equine outbreaks had occurred, to determine which mosquito species at this site were attracted to these traps. We also set out CO2-baited CDC light traps for comparison. Of 11 species present in CO2-baited CDC light traps, only Culex (Melanoconion) erraticus (Dyar and Knab) blood fed on hamsters in the Trinidad traps. Significantly less Cx. erraticus mosquitoes entered Trinidad traps per trap night (mean = 17.6, median = 6.0) compared with CDC traps (mean = 38.7, median = 35.0). Advantages and disadvantages in using hamster-baited no. 17 Trinidad traps compared with CO2-baited CDC light traps to capture Cx. erraticus mosquitoes are discussed. Further understanding of the feeding behavior and ecology of this potential vector is warranted.
我们在田纳西州的一片沼泽地设置了17个用仓鼠作诱饵的17号特立尼达诱捕器，该地区最近发生了东部马脑炎（EEE）马疫情，目的是确定该地点哪些蚊种会被这些诱捕器吸引。我们还设置了用二氧化碳作诱饵的疾控中心灯光诱捕器作比较。在用二氧化碳作诱饵的疾控中心灯光诱捕器捕获的11个蚊种中，只有库蚊（黑须库蚊亚属）（戴尔和克纳布）在特立尼达诱捕器中以仓鼠为血源吸食血液。与疾控中心诱捕器相比，每个诱捕器每晚进入特立尼达诱捕器的不定库蚊显著减少（平均值 = 17.6，中位数 = 6.0）（疾控中心诱捕器平均值 = 38.7，中位数 = 35.0）。本文讨论了与用二氧化碳作诱饵的疾控中心灯光诱捕器相比，使用用仓鼠作诱饵的17号特立尼达诱捕器捕获不定库蚊的优缺点。有必要进一步了解这种潜在病媒的摄食行为和生态学。
