The mortality of Aedes aegypti mosquitoes increased; immediately following a blood meal containing microfilariae of Brugia pahangi, when infective larvae began to migrate out of the flight muscles and when infective larvae were lost from the mosquitoes during a blood meal. When infective mosquitoes took a second blood meal 86.2% of the infective larvae escaped from their bodies. However, only 50.3% escaped when mosquitoes fed through a thin layer of cotton. Infective larvae in the abdomen of the mosquitoes stood the least chance of escaping from the insects. When infective mosquitoes were offered a third blood meal four days later, the proportion of infective larvae in the head and labium had risen from 56.6% in the control group to 66.0% and 69.4% in the two test groups. At this third feed 54.7% and 75.7% of the infective larvae were lost from mosquitoes with a low and medium pre-feeding worm burden respectively. This suggests that the escape of infective larvae from mosquitoes with only a few worms is less efficient than from mosquitoes with a medium worm burden.
埃及伊蚊的死亡率增加；在吸食含有彭亨布鲁线虫微丝蚴的血液后立即增加，在感染性幼虫开始从飞行肌中迁移出来时增加，以及在蚊虫吸食血液期间感染性幼虫从蚊虫体内消失时增加。当感染性蚊虫吸食第二顿血液时，86.2%的感染性幼虫从其体内逸出。然而，当蚊虫通过一层薄棉布吸食时，只有50.3%的感染性幼虫逸出。蚊虫腹部的感染性幼虫从昆虫体内逸出的可能性最小。当在四天后给感染性蚊虫提供第三顿血液时，头部和唇部的感染性幼虫比例从对照组的56.6%分别上升到两个试验组的66.0%和69.4%。在这第三次喂食时，预喂食蠕虫负担低和中等的蚊虫分别有54.7%和75.7%的感染性幼虫丢失。这表明，感染性幼虫从蠕虫数量少的蚊虫体内逸出的效率低于从蠕虫负担中等的蚊虫体内逸出的效率。
