我们确定了埃及伊蚊的空间格局以及它们在秘鲁亚马逊城市伊基托斯的两个社区发育的容器。四个变量进行了检查：成人Ae。埃及伊蚊、脓疱、对幼虫或脓疱呈阳性的容器以及所有盛水容器。成虫在房屋内聚集得很强，在房屋外30米的距离内聚集得很弱;对于阳性容器01，腐殖酸，在10米以外未检测到聚集。在短时间内限制了Ae的飞行范围和频繁的吸血行为。埃及人似乎是人类登革热感染聚集模式的潜在因素。永久性的，一贯出没的容器（关键处所）不是主要生产商的AE。这表明，消灭幼虫战略本身可能不如通过减少来源和教育运动减少蚊子滋生地有效。我们的结论是，人类登革热感染的昆虫学风险应在家庭层面上进行评估，在频繁的时间间隔。
We determine the spatial pattern of Aedes aegypti and the containers in which they develop in two neighborhoods of the Amazonian city of Iquitos, Peru. Four variables were examined: adult Ae. aegypti, pupae, containers positive for larvae or pupae, and all water-holding containers. Adults clustered strongly within houses and weakly to a distance of 30 meters beyond the household; clustering was not detected beyond 10 meters for positive containers 01, pupae. Over short periods of time restricted flight range and frequent blood-feeding behavior of Ae. aegypti appear to be underlying factors in the clustering patterns of human dengue infections. Permanent, consistently infested containers (key premises) were not major producers of Ae. aegypti, indicating that larvaciding strategies by themselves may be less effective than reduction of mosquito development sites by source reduction and education campaigns. We conclude that entomologic risk of human dengue infection should be assessed at the household level at frequent time intervals.
