Aedes aegypti mosquitoes are highly adaptable to abiotic stimuli. To evaluate the influence of shading and pedestrian traffic on the preference of Ae. aegypti for oviposition microenvironments, 20 sites were sampled weekly using ovitraps within the perimeter of Universidade Federal do Espírito Santo, located in São Mateus, Espírito Santo, Brazil. A spatial and statistical analysis was performed in order to assess the relationship between shading time, pedestrian traffic, and the presence of biological forms of Ae. aegypti. A temporal analysis of temperature and precipitation influence on oviposition was also made. Between June, 2013 and June, 2014, 7,362 Ae. aegypti eggs were collected. Over a 12-month period, we made weekly collections of Ae. aegypti eggs from ovitraps. Pedestrian traffic and shading time influenced the number of positive ovitraps; precipitation and temperature were correlated with the number of positive ovitraps (p <0.05). We conclude that the influence of temperature and precipitation was not significant for the oviposition index, and the frequency of oviposition was directly proportional to the number of individuals moving close to the traps during periods of greater shading.
埃及伊蚊对非生物刺激具有高度适应性。为评估遮荫和行人流量对埃及伊蚊产卵微环境偏好的影响，在巴西圣埃斯皮里图州圣马特乌斯市的圣埃斯皮里图联邦大学周边区域，每周使用诱蚊产卵器对20个地点进行采样。进行了空间和统计分析，以评估遮荫时间、行人流量与埃及伊蚊生物形态存在之间的关系。还对温度和降水对产卵的影响进行了时间分析。在2013年6月至2014年6月期间，共收集到7362枚埃及伊蚊卵。在12个月的时间里，我们每周从诱蚊产卵器中收集埃及伊蚊卵。行人流量和遮荫时间影响了诱蚊产卵器阳性的数量；降水和温度与诱蚊产卵器阳性数量相关（p<0.05）。我们得出结论，温度和降水对产卵指数的影响不显著，产卵频率与在遮荫时间较长时靠近诱捕器活动的个体数量成正比。
