Two outbreaks of Plasmodium vivax malaria have occurred recently in southern California, and Anopheles hermsi, a newly described species closely related to A freeborni, has been implicated as the vector. To assess the competence of A. hermsi as a vector, its susceptibility to P. vivax was compared with that of the efficient vector A. freeborni by allowing 150 females of each species to feed to repletion on infected squirrel monkeys. Oocyst density was greater in A. hermsi than in A. freeborni, and the frequency and density of sporozoites were similar. A. hermsi was susceptible to P. vivax and readily supported development to the sporozoite stage.
最近在南加利福尼亚发生了两起间日疟原虫疟疾疫情，一种新描述的与弗里伯恩按蚊密切相关的赫氏按蚊被认为是传播媒介。为了评估赫氏按蚊作为传播媒介的能力，通过让每个物种的150只雌蚊饱食感染的松鼠猴，将其对间日疟原虫的易感性与高效传播媒介弗里伯恩按蚊的易感性进行了比较。赫氏按蚊的卵囊密度高于弗里伯恩按蚊，子孢子的频率和密度相似。赫氏按蚊对间日疟原虫易感，并能轻易支持其发育到子孢子阶段。
