Abstract

From June 19, 2003 to August 18, 2003, we surveyed the mosquitoes of Oberlin, OH, for West Nile Virus (WNV) infection using reverse transcriptase-polymerase chain reaction. A total of 12,055 mosquitoes, representing 17 species or species groups and 4 genera, were collected in gravid traps at seven sites throughout the city, with Culex pipiens/restuans being the most abundant and showing the highest minimum infection rate (MIR) of 0.78. This represents a decrease in WNV enzootic activity from the previous year. Both Cx. pipiens/restuans abundance and MIR increased significantly with date. However, we found no correlation between Cx. pipiens/restuans abundance and MIR.

摘要

2003年6月19日至2003年8月18日，我们利用逆转录聚合酶链反应对俄亥俄州奥伯林市的蚊子进行了西尼罗河病毒（WNV）感染情况调查。在全市七个地点的诱蚊产卵器中，共收集到12,055只蚊子，分属4个属的17个物种或物种组，其中尖音库蚊/致倦库蚊数量最多，最低感染率（MIR）最高，为0.78。这表明西尼罗河病毒的动物宿主活动较上一年有所下降。尖音库蚊/致倦库蚊的数量和最低感染率均随日期显著增加。然而，我们发现尖音库蚊/致倦库蚊的数量与最低感染率之间没有相关性。
