Villages under the escarpment of the Tanzanian plateau were surveyed for breeding of Aedes aegypti. In some places more than 27% of the water containers outside houses harboured A. aegypti larvae, while there was practically no breeding in containers inside houses. From 2% to 10% of tree holes contained A. aegypti larvae. In places, as many as 47 A. simpsoni larvae were collected from one pineapple plant, and the total mean number of larvae per pineapple was 6.6, while the percentage of plants with larvae was as high as 93.6. The total mean number of larvae per colocasia plant was 2.9, but the number per banana plant was only 0.3. The plant Crinum was discovered to be a breeding site of A. simpsoni. Eggs of A. simpsoni were found in 55-80% of ovitraps placed in four villages. Of 20 traps found to contain eggs of this species 30% were in the village, 60% in gardens, and 10% at the edge of forest. It was observed that A. simpsoni females lay their eggs at all levels up to 5 m, but prefer ground level.
对坦桑尼亚高原悬崖下的村庄进行了埃及伊蚊繁殖情况的调查。在一些地方，房屋外超过27%的盛水容器中有埃及伊蚊幼虫，而房屋内的容器中几乎没有繁殖现象。2%至10%的树洞中有埃及伊蚊幼虫。在一些地方，从一棵菠萝植株上收集到多达47条辛普森伊蚊幼虫，每棵菠萝植株上幼虫的平均总数为6.6条，而有幼虫的植株所占百分比高达93.6%。每株芋头植株上幼虫的平均总数为2.9条，但每株香蕉植株上仅为0.3条。发现文殊兰属植物是辛普森伊蚊的一个繁殖场所。在四个村庄放置的诱蚊产卵器中，55%至80%发现有辛普森伊蚊的卵。在发现含有该物种卵的20个诱捕器中，30%在村庄内，60%在花园中，10%在森林边缘。据观察，辛普森伊蚊雌蚊在高达5米的各个高度都产卵，但更喜欢在地面高度产卵。
