美国北卡州有犬恶丝虫病流行。在沿海高发区对其媒介及其相对数与感染率进行了调查。发现An.bradleyi,带喙伊蚊与Ae.sollicitansy为其媒介。最高感染率出现在1985年6—7月份。根据相对数量与感染率(1.2％)认为An.bradleyi为主要媒介。在实验条件下对Ae.sollicitans与带喙伊蚊的媒介效能进行了研究,让雌蚊吸食43400个微丝蚴/ml的感染血,感染后第15天,感染幼虫的平均数Ae.sollicitans为22.9,带喙伊蚊1.44,但Ae.sollicitans的死亡率却高达48.5％,提示带喙伊蚊对犬恶虫丝感染更为敏感。
Dirofilaria is endemic in North Carolina. Their media, their relative numbers and their infection rates were investigated in high-risk coastal areas. An.bradleyi was found, with Aedes albopictus and Ae.sollicitansy as its medium. The highest infection rate occurred in June-July 1985. According to the relative number and infection rate (1.2%) that An.bradleyi as the main medium. The vector efficacy of Ae.sollicitans and Ae. Aegypti was studied under experimental conditions, allowing female mosquitoes to infect 43400 microfilariae / ml of infected blood. The mean number of infected larvae, Ae.sollicitans, was 15 days post-infection 22.9 and Aedes albopictus 1.44, but Ae.sollicitans mortality rate was as high as 48.5%, suggesting that Aedes albopictus is more susceptible to silkworm infection.
