We assessed the presence of in five ecorregions of Salta province and compared the oviposition activity of using ovitraps in towns of two contrasting ecoregions (yungas and Chaco dry forests) in the province of Salta, Argentina, a major contrast in these ecoregions are rain patterns and altitude. Our aim was to estimate how oviposition activities were associated with the ecoregion and site scale local environmental variables. Mosquito oviposition activity was monitored weekly during the summer using ovitraps. Predictor variables were ecoregion, town, and meteorological variables. The effect of the predictor variables was measured on the response variables using multi-model inference. Besides yungas, the presence of was confirmed in towns of dry Chaco and High Monte. The only factor that had a significant effect on the presence of eggs in the ovitraps was the ecoregion, with the frequency of positives being higher in yungas. For the number of eggs, the ecoregion, the night temperature of the first week and the NDVI would explain said variable. Overall, results indicate that the variations between towns would be more related with their ecological and climatic characteristics than with the more immediate meteorological variations.

阿根廷萨尔塔永加斯和干查科人口密度低的城镇埃及伊蚊产卵动态

我们评估了萨尔塔省五个生态区的存在情况，并比较了阿根廷萨尔塔省两个对比生态区（永加斯和查科干旱森林）的城镇中使用产卵器的产卵活动，这些生态区的主要对比是降雨模式和高度。我们的目的是估计产卵活动与生态区和场地规模的当地环境变量之间的关系。夏季期间，使用产卵器每周监测蚊子的产卵活动。预测变量是生态区、城镇和气象变量。使用多模型推理测量预测变量对响应变量的影响。除了永加斯之外，干燥的查科镇和高蒙特镇也证实存在。对产卵器中卵的存在有显着影响的唯一因素是生态区，其中阳性频率在云加斯中更高。对于鸡蛋的数量，生态区、第一周的夜间温度和 NDVI 可以解释该变量。总体而言，结果表明，城镇之间的差异与其生态和气候特征的关系更大，而不是与更直接的气象变化的关系。
