目的掌握来自西尼罗热疫区入境国际航行船舶携带输入性蚊媒的情况,为制定有效的控制措施提供科学依据。方法在检疫锚地对来自西尼罗热疫区的入境国际航行船舶携带的输入性蚊媒情况进行调查研究,对采集的标本进行计数和分类鉴定,并对结果进行统计分析。结果2001-2005年共调查13艘次来自西尼罗热疫区入境国际航行船舶,携带输入性蚊类船舶阳性率平均为84.62%(11/13),已鉴定确认的蚊种达6种,分属蚊科的库蚊属、伊蚊属。凶小库蚊、淡色库蚊和三带喙库蚊等可传播西尼罗热的媒介蚊种为优势种。结论调查证明来自西尼罗热疫区的入境国际航行船舶携带输入性蚊媒的情况相当严重,对此应给予高度关注。 OBJECTIVE To grasp the situation of imported mosquito vectors entering the international voyage from the West Nile fever epidemic area and provide a scientific basis for the formulation of effective control measures. Methods The imported mosquito vectors carried by incoming international voyages from the West Nile epidemic area were investigated at the quarantine anchorage. The collected specimens were counted and classified, and the results were statistically analyzed. Results A total of 13 shipments coming in from the West Nile fever epidemic area during 2001-2005 were investigated. The positive rates of imported mosquitoes were 84.62% (11/13), 6 were identified as mosquito species, Belong to the mosquito Culex, Aedes. Culex pipiens pallens, Culex pipiens pallens, Culex tritaeniorhynchus and Culex tritaeniorhynchus were the dominant mosquito species that could transmit West Nile fever. Conclusions The investigation shows that the imported mosquito-borne mosquito vectors entering the international voyages from the West Nile fever epidemic area are rather serious and should be given high attention.
