The distribution of Aedes aegypti (L) (Diptera: Culicidae) oviposition in Buenos Aires City is spatially heterogeneous. Oviposition activity was monitored for a year with a grid of 279 traps at 850-m intervals that were serviced weekly. Geostatistics were used for the spatial analysis and generalized linear regression to model oviposition as a function of demographic and environmental variables. The proportion of weeks infested and the total number of eggs showed spatial continuity and were higher in areas that had higher densities of houses and were closer to industrial sites; they were lower in areas with higher human populations or higher densities of flats. When all sites were considered, the spatial structure showed a strong trend, but after regression, the residuals presented lower spatial dependence. When only infested sites were considered, the oviposition variables were spatially autocorrelated and the regression residuals showed little or no spatial dependence. The spatial pattern of Ae. aegypti oviposition in a highly urbanized city such as Buenos Aires seems to be related to the urbanization gradient. These urban environments might present different resource availability or continuity between patches of resources.
埃及伊蚊（双翅目：蚊科）在布宜诺斯艾利斯市的产卵分布在空间上是异质的。通过一个由279个诱捕器组成的网格，以850米的间隔每周进行维护，对产卵活动进行了为期一年的监测。地统计学用于空间分析，并使用广义线性回归将产卵作为人口和环境变量的函数进行建模。受侵染周数的比例和卵的总数显示出空间连续性，在房屋密度较高且靠近工业场所的地区更高；在人口较多或公寓密度较高的地区则较低。当考虑所有地点时，空间结构呈现出强烈的趋势，但回归后，残差呈现出较低的空间依赖性。当仅考虑受侵染的地点时，产卵变量在空间上是自相关的，回归残差显示出很少或没有空间依赖性。在像布宜诺斯艾利斯这样高度城市化的城市中，埃及伊蚊的产卵空间模式似乎与城市化梯度有关。这些城市环境可能呈现出不同的资源可用性或资源斑块之间的连续性。
