在法属波利尼西亚，波利尼西亚伊蚊是由亚周期性班氏吴策线虫（Wuchereria bancrofti）（Cobbold）引起的人类丝虫病的主要媒介。评估了影响感染性幼虫从病媒向人传播的因素。在血餐期间，感染性幼虫的66-100%损失与初始媒介寄生虫负荷无关。感染性幼虫能够在血餐期间迁移到口器。吸血饱腹是幼虫逃逸的一个重要方面。感染性幼虫在没有血餐的情况下不会传播（丢失），并且可以在媒介的身体Ae中移动。波利尼西亚线虫可能在几天内保持感染潜力，并可能在一次血餐期间或在几个生殖营养周期中感染几个宿主。在寄生虫传播方面，这些发现被解释为丝虫对Ae的有效适应。波利尼西亚人咬人的习性
In French Polynesia, Aedes polynesiensis Murks is the major vector of human filariasis caused by subperiodic Wuchereria bancrofti (Cobbold). Factors affecting transmission of infective larvae from vector to humans were assessed. The 66-100% loss of infective larvae during a blood meal was independent of the initial vector parasite burden, Infective larvae were able to migrate to the mouthparts during a blood meal. Blood feeding by mosquitoes to repletion was one important aspect in the escape of larvae. Infective larvae were not transmitted (lost) without a blood meal and mai move in the vector's body Ae. polynesiensis may retain infectivity potential during several days and may infect several hosts during one blood meal session or on several gonotrophic cycles. In terms of parasite transmission, these findings were interpreted as efficient adaptations of the filaria to the Ae. polynesiensis biting habits.
