人们越来越关注由节肢动物传播的病毒（虫媒病毒）在人类和动物中引起的疾病暴发的风险。有几种蚊媒病毒性疾病会导致马不同程度的发病率和死亡率，并可能产生重大的福利和经济后果。虽然在英国没有记录，但存在其中一些病毒的载体物种，这表明英国马可能处于危险之中。因此，作者在英国进行了第一次关于马场所蚊子种类的研究。采用磁捕蚊器和红盒诱捕器对成虫进行采样，并从轮胎、水桶、沟渠和水池等水源中采集幼虫。捕获了几种已知能够传播重要的马传染性虫媒病毒的种属。最丰富的，在72小时内的最大渔获量为173，是Ochlerotatus碎屑，一些黄病毒的主管载体，密度最高的盐沼栖息地附近。 分布最广的物种是Culiseta annulata，在超过75%的地点有记录。这项研究表明，潜在的蚊子媒介虫媒病毒，包括那些已知能够感染马，是存在的，可能是丰富的马的处所在英国。
There is growing concern about the increasing risk of disease outbreaks caused by arthropod-borne viruses (arboviruses) in both human beings and animals. There are several mosquito-borne viral diseases that cause varying levels of morbidity and mortality in horses and that can have substantial welfare and economic ramifications. While none has been recorded in the UK, vector species for some of these viruses are present, suggesting that UK equines may be at risk. The authors undertook, therefore, the first study of mosquito species on equine premises in the UK. Mosquito magnet traps and red-box traps were used to sample adults, and larvae were collected from water sources such as tyres, buckets, ditches and pools. Several species that are known to be capable of transmitting important equine infectious arboviruses were trapped. The most abundant, with a maximum catch of 173 in 72 hours, was Ochlerotatus detritus, a competent vector of some flaviviruses; the highest densities were found near saltmarsh habitats. The most widespread species, recorded at >75 per cent of sites, was Culiseta annulata. This study demonstrates that potential mosquito vectors of arboviruses, including those known to be capable of infecting horses, are present and may be abundant on equine premises in the UK.
