The Asian tiger mosquito, Aedes albopictus, is a competent vector for arboviruses and recently was implicated as the vector of the first autochthonous cases of dengue and chikungunya in southern Europe. The objective of this study was to analyze the flight performance of female Ae. albopictus of different ages that were starved, sugar-fed, or sugar-fed and blood-fed, using flight mills. After three days of starvation post emergence, females flew an average distance of 0.7 ± 0.5 km in 1.9 ± 1.5 h during a 16 h trial period, whereas sugar- or sugar- and blood-fed females of this age covered a significantly higher distance of around 3 km with a mean total flight time of around 6 h. The age of females (up to four weeks) had no effect on performance. The average of maximal continuous flight segments of sugar-fed (2.14 ± 0.69 h) and blood-fed (3.17 ± 0.82 h) females was distinctly higher than of starved females (0.38 ± 0.15 h) of which most flyers (83%) performed maximal flight segments that lasted no longer than 0.5 h. Overall, the results for the laboratory monitored flight performance of Ae. albopictus confirm their ability to disperse a few kilometres between breeding site and host.
亚洲虎蚊,即白纹伊蚊,是虫媒病毒的有效传播媒介,最近被认定为欧洲南部首批登革热和基孔肯雅热本地病例的传播媒介。本研究的目的是使用飞行磨分析不同年龄、处于饥饿状态、取食糖水或取食糖水并吸食血液的雌性白纹伊蚊的飞行性能。羽化后饥饿三天的雌性白纹伊蚊,在16小时的试验期内,平均在1.9±1.5小时内飞行0.7±0.5千米,而这个年龄段取食糖水或取食糖水并吸食血液的雌性白纹伊蚊飞行距离明显更长,约为3千米,平均总飞行时间约为6小时。雌性白纹伊蚊的年龄(四周以内)对飞行性能没有影响。取食糖水的雌性白纹伊蚊(2.14±0.69小时)和吸食血液的雌性白纹伊蚊(3.17±0.82小时)的最大连续飞行时段平均值明显高于饥饿的雌性白纹伊蚊(0.38±0.15小时),其中大多数飞行者(83%)的最大飞行时段持续时间不超过0.5小时。总体而言,实验室对白纹伊蚊飞行性能的监测结果证实了它们在繁殖地和宿主之间传播数公里的能力。
