The arrival and establishment of Aedes (Finlaya) japonicus japonicus (Theobald) (Diptera: Culicidae) in Iowa are reported. In total, 518 wild adult specimens were collected through the statewide mosquito and mosquito-borne virus surveillance program in 2007 and 2008. Specimens were collected with New Jersey light traps, CO2-baited CDC light traps, grass infusion-baited gravid traps, and Mosquito Magnet traps located in 12 counties in central and eastern Iowa Specimens were identified morphologically, and identity was further supported by molecular DNA barcoding. Specimens also were tested for infection with West Nile virus (family Flaviviridae, genus Flavivirus, WNV) and La Crosse virus (family Bunyaviridae, genus Bunyavirus, LACV) by reverse transcription-polymerase chain reaction. Although no specimens tested positive for arbovirus infection, the arrival of Ae. j. japonicus in Iowa is a public health concern considering its potential to transmit several arboviruses, particularly WNV and LACV.
报道了伊蚊(远东伊蚊)在爱荷华州的出现和建立。在 2007 年和 2008 年,通过全州范围内的蚊子和蚊媒病毒监测计划共收集了 518 只野生成年标本。标本是用新泽西州诱蚊灯、CO2 引诱的 CDC 诱蚊灯、草浸液引诱的妊娠诱蚊器和 Mosquito Magnet 诱蚊器在爱荷华州中部和东部的 12 个县收集的。标本通过形态学进行鉴定,通过分子 DNA 条形码进一步支持鉴定结果。还通过逆转录-聚合酶链反应检测标本是否感染西尼罗河病毒(黄病毒科,黄病毒属,WNV)和拉克罗斯病毒(布尼亚病毒科,布尼亚病毒属,LACV)。尽管没有标本检测出虫媒病毒感染呈阳性,但考虑到其传播几种虫媒病毒的潜力,特别是西尼罗河病毒和拉克罗斯病毒,伊蚊在爱荷华州的出现引起了公共卫生关注。
