Abstract

The host preference of 4 Culex mosquito species collected in Miaoli and Pingtung counties, Taiwan was studied by capillary precipitin method. Antisera to alum-precipitated sera of man, bovine, swine, rabbit, horse, dog, cat, mouse, chicken, duck, and pigeon were produced in rabbits and reacted with 758 mosquito blood meals among which reactions to one or more antisera. Culex annulus and Culex tritaeniorhynchus summorosus showed a great avidity for pig, and Culex fuscocephala for bovine. Culex pipiens fatigans was ornithophilic. None of 110 C. t. summorosus and 2.4% of 223 C. annulus had fed on man. Among 66 samples of C.p. fatigans tested 10.3% had fed on man, while none of 359 C. fuscocephala did. It seems that the latter does not act as a primary vector of Japanese encephalitis.

乙型脑炎蚊媒的宿主偏好。
采用毛细沉淀法对台湾省苗栗县和屏东县4种库蚊的寄主偏好进行了研究。在家兔中制备了人、牛、猪、兔、马、狗、猫、鼠、鸡、鸭和鸽的铝沉淀血清的抗血清,并与758份蚊血餐反应,其中对一种或多种抗血清有反应。环状库蚊和三带喙库蚊对猪和牛表现出极强的嗜性。疲劳库蚊嗜鸟。110只沙锥蝽和223只环锥蝽均未采食人。在66个样本中,10.3%的样本有食人行为,而359个样本中没有食人行为。后者似乎不是日本脑炎的主要媒介。
