We report the results of three mark-release-recapture experiments carried out in an urban area in Rome, Italy, to study the active dispersal of Aedes albopictus (Diptera: Culicidae). The 4.3% recapture rate obtained supports the use of sticky traps in MRR experiments to study the dispersal of Ae. albopictus females. Most fluorescent dust-marked females were recaptured at the gravid stage at 50-200 m from the release sites during the first 9 days after release. The average of daily-MDTs (Mean Distance Traveled) was 119 m and the maximum observed distance travelled ranged from 199 m to 290 m in the three replicates. These data provide the first information about the dispersal of Ae. albopictus in a temperate European area and appear to be consistent with the few data available on this subject from other urban areas, where dispersal was constrained by physical barriers. Although caution should be taken in generalizing these results, they should be considered when planning control activities in urban areas in Italy, as well as in other European countries. This is particularly relevant if control is intended to interrupt pathogen transmission in cases of possible arbovirus epidemics, such as the Chikungunya outbreak that occurred in Ravenna, Italy in 2007.
我们报告了在意大利罗马的一个市区进行的三项标记释放再捕获实验的结果，以研究白纹伊蚊（双翅目：蚊科）的主动扩散。所获得的4.3%的再捕获率支持在标记释放再捕获实验中使用粘性诱捕器来研究白纹伊蚊雌蚊的扩散。大多数带有荧光粉尘标记的雌蚊在释放后的前9天内，于距离释放点50 - 200米处的孕卵期被重新捕获。在三个重复实验中，每日平均移动距离（MDT）为119米，观察到的最大移动距离在199米至290米之间。这些数据提供了关于白纹伊蚊在欧洲温带地区扩散的首个信息，并且似乎与其他市区关于该主题的少量可用数据一致，在那些市区，扩散受到物理屏障的限制。尽管在推广这些结果时应谨慎，但在意大利以及其他欧洲国家的市区规划控制活动时应考虑这些结果。如果控制旨在在可能的虫媒病毒流行（如2007年在意大利拉文纳发生的基孔肯雅热疫情）情况下中断病原体传播，这一点尤其相关。
