实验室饲养的白纹伊蚊Skuse男性的传播和生存进行了调查，在2007年夏天在三个北方意大利城市地区的标记释放-再捕获技术。两种标记方法进行了比较：一组男性身上撒上荧光色素（FP），另一组是从一个菌株，其自然感染的沃尔巴克氏体已被删除（WB 0）。FP-和WB 0标记的男性被释放为成年人和pupelies，分别在一个固定站在每个地方。在释放后第4、5和7天，由熟练的技术人员在距离释放地点350 m半径范围内进行重新捕获，并在技术人员身体周围飞行或成群飞行时收集雄性。FP雄性动物的再捕获率范围为0.63 - 4.72%，WBO雄性动物的再捕获率范围为2.39 - 11.05%。WBO男性的平均行进距离显着高于FP男性，没有观察到差异的传播距离测量的男性重新捕获人类宿主与男性重新捕获，而蜂拥而至。没有进一步增加的扩散发生在postrelease期间调查（从第4天到第7天后释放）。在释放时，FP标记雄性的平均存活率为0.51，WBO雄性为0.81。本文讨论了这些数据对制定防治山羊草不育技术方案的意义。白纹伊蚊
The dispersal and survival of laboratory-reared Aedes albopictus Skuse males were investigated during the summer of 2007 in three Northern Italy urban localities by mark-release-recapture techniques. Two marking methods were compared: one group of males was dusted with fluorescent pigments on the body (FP), and the other group was obtained from a strain whose natural infection of Wolbachia had been removed (WB0). FP- and WB0-marked males were released as adults and pupae, respectively, in one fixed station at each locality. Recaptures were performed by skilled technicians, within a radius of 350 m from the release site, on days 4, 5, and 7 after the release, and the males were collected while flying around the technician's body or in swarms. Recapture rates ranged from 0.63 to 4.72% for FP males and from 2.39 to 11.05% for WBO males. The mean distance traveled for WBO males was significantly higher than for FP males; no difference was observed between the dispersal distance measured for the males recaptured on human host versus males recaptured while swarming. No further increase of the dispersal occurred during the postrelease period investigated (from day 4 to day 7 after release). The mean survival rate at the release was 0.51 for FP-marked males and 0.81 for WBO males. The data obtained are discussed for their significance in planning sterile insect technique programs against Ae. albopictus.
