Field collections of mosquitoes were made April-September 1977 and 1978 in the immediate vicinity of a hunting-dog kennel where the dogs had a chronic history of heartworm infection. Among 19 mosquito species taken in light-trap collections, only Aedes sticticus, Ae. vexans, and Anopheles punctipennis were found infected with what were presumed to be D. immitis larvae. Based on natural infection rates and the relative abundance of these three host species, An. punctipennis and Ae. sticticus appear to be among the most important vectors of dog heartworm at this site. Despite its greater abundance, Ae. vexans apparently plays a comparatively lesser role in D. immitis transmission owing to low natural infection rates and the development of only a few filariae per host. All Dirofilaria isolations were made in April, May, and June, suggesting that transmission may occur primarily during the spring and early summer in this area.
1977年4月至9月以及1978年同期，在一个猎用犬舍附近进行了蚊虫野外采集，该犬舍的犬类有长期的心丝虫感染病史。在灯光诱捕采集到的19种蚊虫中，只有窄翅伊蚊、刺扰伊蚊和致倦库蚊被发现感染了疑似犬恶丝虫幼虫。根据这三种宿主种类的自然感染率和相对丰度，致倦库蚊和窄翅伊蚊似乎是该地点犬心丝虫最重要的传播媒介。尽管刺扰伊蚊数量更多，但由于其自然感染率低且每个宿主仅发育少数丝虫，它在犬恶丝虫传播中显然发挥的作用相对较小。所有犬恶丝虫分离株均在4月、5月和6月获得，这表明该地区的传播可能主要发生在春季和初夏。
