布宜诺斯艾利斯市埃及伊蚊产卵的空间分布具有异质性。产卵活动监测了一年的网格279个陷阱在850米的间隔，每周提供服务。地统计学用于空间分析和广义线性回归模型产卵作为人口和环境变量的函数。周出没的比例和鸡蛋总数显示空间连续性，并在具有较高密度的房屋和更接近工业用地的地区较高;他们在人口较多或单位密度较高的地区较低。当考虑所有站点时，空间结构表现出强烈的趋势，但回归后，残差表现出较低的空间依赖性。当只被认为是虫害的网站，产卵变量的空间自相关和回归残差显示很少或没有空间依赖性。的空间格局。埃及伊蚊产卵在一个高度城市化的城市，如布宜诺斯艾利斯似乎是与城市化梯度。这些城市环境可能会呈现不同的资源可用性或资源斑块之间的连续性。
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.
