Eight years after the introduction and establishment of Aedes albopictus in Roma, females of the species extended their trophic activity to the coldest months of the year. Winter monitoring carried out from December 2003 to March 2004 in the urban area of the capital city of Italy recorded a weekly rate of positive ovitraps constantly around 30%, for the entire period of surveillance (14 wk). Eggs from ovitraps did not hatch when stimulated in laboratory with a wet and dry procedure. The hypothesis that long-lived female Ae. albopictus, belonging to the last seasonal generation, could have continued their trophic activity for 3 months, or that 1 or more cycles of reproduction have occurred in peculiar breeding sites, where a favorable microclimate may have allowed the development of at least 1 larval generation, are discussed and compared with the existing literature.
白纹伊蚊引入并在罗马定殖八年后，该物种的雌蚊将其摄食活动扩展到了一年中最寒冷的月份。2003年12月至2004年3月在意大利首都市区进行的冬季监测记录显示，在整个监测期（14周）内，诱蚊产卵器的阳性周率始终保持在30%左右。在实验室中，用干湿处理刺激诱蚊产卵器中的卵时，这些卵并未孵化。本文讨论了以下假设，并与现有文献进行了比较：属于最后一个季节性世代的长寿白纹伊蚊雌蚊可能持续其摄食活动达三个月，或者在特殊的繁殖地点发生了一个或多个繁殖周期，在这些地点，有利的小气候可能使至少一代幼虫得以发育。
