Transmission experiments of laboratory-bred and wild-caught Aedes polynesiensis and wild-caught Ae. samoanus on carriers with different levels of microfilaraemia showed that the percentage of mosquitoes infected, the average number and range of larvae found in each infected mosquito were directly proportional to the microfilarial densities in the carrier at the time of feeding. There was no difference between the results for laboratory-bred and wild-caught mosquitoes. Aedes polynesiensis fed on low carriers (around 20 Mf ml-1 and less) gave an average infection rate of 4.9%. Each infected mosquito harboured only one larva. A plot of the probit of percentage Ae. polynesiensis positive against the logarithm of microfilarial density showed a linear relationship. Using the regression line, at 95% confidence interval, a microfilarial density of 1 ml-1 would give an infection rate of 0.22-2.51%, a density of 0.1 Mf ml-1 an infection rate of 0.01-1.0%. The concentrating capacity of Ae. polynesiensis ranged from 0.70 to 4.74. As microfilaria densities decreased, concentration increased. The microfilarial intake, the subsequent worm burden and concentrating capacity were less in Ae. samoanus than Ae. polynesiensis. There was no evidence of any association between microfilarial density and concentration in Ae. samoanus.
对实验室培育的和野外捕获的波利尼西亚伊蚊以及野外捕获的萨摩亚伊蚊在不同微丝蚴血症水平的携带者身上进行传播实验，结果表明，感染蚊子的百分比、每只感染蚊子体内发现的幼虫平均数量和范围与喂食时携带者体内的微丝蚴密度成正比。实验室培育的蚊子和野外捕获的蚊子的实验结果没有差异。以低微丝蚴血症水平携带者（约每毫升20条微丝蚴及以下）为食的波利尼西亚伊蚊平均感染率为4.9%。每只感染的蚊子仅携带一条幼虫。以波利尼西亚伊蚊阳性百分比的概率单位对微丝蚴密度的对数作图显示呈线性关系。利用回归线，在95%置信区间下，每毫升1条微丝蚴的密度会产生0.22 - 2.51%的感染率，每毫升0.1条微丝蚴的密度会产生0.01 - 1.0%的感染率。波利尼西亚伊蚊的浓缩能力在0.70至4.74之间。随着微丝蚴密度降低，浓缩能力增加。萨摩亚伊蚊的微丝蚴摄入量、随后的虫负荷和浓缩能力低于波利尼西亚伊蚊。没有证据表明萨摩亚伊蚊的微丝蚴密度与浓缩能力之间存在任何关联。
