BACKGROUND Fluctuations in climate have been associated with variations in mosquito abundance. OBJECTIVES To analyse the influence of precipitation, temperature, solar radiation, wind speed and humidity on the oviposition dynamics of Aedes aegypti in three distinct environmental areas (Brasília Teimosa, Morro da Conceição/Alto José do Pinho and Dois Irmãos/Pintos) of the city of Recife and the Fernando de Noronha Archipelago northeastern Brazil. METHODS Time series study using a database of studies previously carried out in the areas. The eggs were collected using spatially distributed geo-referenced sentinel ovitraps (S-OVTs). Meteorological satellite data were obtained from the IRI climate data library. The association between meteorological variables and egg abundance was analysed using autoregressive models. FINDINGS Precipitation was positively associated with egg abundance in three of the four study areas with a lag of one month. Higher humidity (β = 45.7; 95% CI: 26.3 - 65.0) and lower wind speed (β = −125.2; 95% CI: −198.8 - −51.6) were associated with the average number of eggs in the hill area. MAIN CONCLUSIONS The effect of climate variables on oviposition varied according to local environmental conditions. Precipitation was a main predictor of egg abundance in the study settings.

巴西东北部四个环境不同的地区气象变量对埃及伊蚊（双翅目：蚊科）产卵动态的影响。

背景技术气候波动与蚊子丰度的变化有关。目的 分析降水、温度、太阳辐射、风速和湿度对城市三个不同环境区域（巴西利亚 Teimosa、Morro da Conceição/Alto José do Pinho 和 Dois Irmãos/Pintos）埃及伊蚊产卵动态的影响累西腓和巴西东北部的费尔南多-迪诺罗尼亚群岛。方法 使用先前在该领域进行的研究数据库进行时间序列研究。使用空间分布的地理参考哨兵产卵器（S-OVT）收集卵。气象卫星数据来自 IRI 气候数据库。使用自回归模型分析了气象变量与鸡蛋丰度之间的关联。结果 在四个研究区域中的三个区域中，降水量与卵子丰度呈正相关，且滞后一个月。较高的湿度（β = 45.7；95% CI：26.3 - 65.0）和较低的风速（β = -125.2；95% CI： -198.8 - -51.6）与山区的平均鸡蛋数量相关。主要结论气候变量对产卵的影响因当地环境条件而异。在研究环境中，降水量是鸡蛋丰度的主要预测因素。
