A 1-year arbovirus study was conducted at The Wedge Plantation located in coastal South Carolina to determine the occurrence and level of arbovirus activity in mosquito species inhabiting the site. Mosquito species composition and temporal abundance were also determined. A total of 45,051 mosquitoes representing 27 species in 9 genera was collected and identified during 130 trap-nights between August, 1997, and July, 1998. The most abundant species was Culex salinarius (n = 20,954) followed by Ochlerotatus taeniorhynchus (n = 12,185). Eastern equine encephalomyelitis virus (EEE) was isolated from 2 pools collected in August, 1997; one pool of Oc. taeniorhynchus (minimum infection rate [MIR] = 0.6/1,000) and a second of Culiseta melanura (MIR = 3.8/1,000). This report represents the first record of an EEE isolation from Oc. taeniorhynchus and Cs. melanura in South Carolina.
在南卡罗来纳州沿海的威奇种植园进行了一项为期1年的虫媒病毒研究，以确定栖息在该地点的蚊虫种类中虫媒病毒的发生情况和活动水平。还确定了蚊虫种类组成和时间丰度。在1997年8月至1998年7月的130个诱捕夜期间，共收集并鉴定了代表9个属27个种类的45,051只蚊子。数量最多的种类是盐泽库蚊（n = 20,954），其次是环跗伊蚊（n = 12,185）。从1997年8月收集的2组样本中分离出东部马脑炎病毒（EEE）；一组是环跗伊蚊（最小感染率[MIR] = 0.6/1,000），另一组是黑尾脉毛蚊（MIR = 3.8/1,000）。本报告是南卡罗来纳州从环跗伊蚊和黑尾脉毛蚊中分离出EEE的首次记录。
