摘　　要：在实验室条件下,致乏库蚊幼虫可大量摄食鱼腥藻,并能消化利用,完成生活史。鱼腥藻在蚊幼虫肠道中滞 留时间约6h,酵母约5h,鱼腥藻比酵母稍难消化。蚊幼虫至化蛹时期相比,饲喂鱼腥藻为194h,而饲喂酵母的为 142h,饲喂鱼腥藻比饲喂酵母延缓了蚊幼虫期52h。Under the laboratory condition, the larvae of Culex pipens fatigans may feed mainly on Anabaena sp and complete their life cycle. The retention time of Anabaena sp. in larval intestine is about 6 hours while that of Saccharomyces sp. is about 5 hours, meaning that Anabaena sp. is not so digestible for the larvae. From hatching to pupation, the larvae fed with Anabaena sp.lasted 194 hours and those fed with Saccharomyces sp were 142 hours, showing that the duration for completing larval stage of the former is 52 hours, which is longer than those fed on Saccharomyces.
