, a deer ked native to Japan, has established itself in several European countries and was recently recorded in Italy. This hippoboscid ectoparasite can develop high density populations, causing annoyance to animals and concern regarding the potential risk of transmitting pathogens to humans. No monitoring or control methods for have been applied or tested up to now. This research evaluated the possible response of winged adults to different colours as the basis for a monitoring and control strategy. In the summer of 2020, a series of six differently coloured sticky panels were randomly set as traps in a wooded area used by deer for resting. The results indicated a clear preference of the deer ked for the blue panels that caught the highest number of flies during the experimental period. Lower numbers of flies were trapped on the red, green, black, and white panels, with the yellow panels recording the fewest captures. The response clearly demonstrates that this species displays a colour preference, and that coloured traps might be useful for monitoring and limiting this biting ectoparasite in natural areas harbouring wildlife and visited by people.
日本本土的鹿虱蝇已在几个欧洲国家定居，最近在意大利也有记录。这种虱蝇外寄生虫可形成高密度种群，给动物带来困扰，并引发对其向人类传播病原体潜在风险的担忧。到目前为止，尚未应用或测试针对鹿虱蝇的监测或控制方法。本研究评估了有翅成虫对不同颜色的可能反应，以此作为监测和控制策略的基础。2020年夏天，在鹿用于休息的林区随机设置了一系列六个不同颜色的粘性面板作为诱捕器。结果表明，鹿虱蝇明显偏好蓝色面板，在实验期间捕获的苍蝇数量最多。红色、绿色、黑色和白色面板上捕获的苍蝇数量较少，黄色面板捕获的苍蝇数量最少。这一反应清楚地表明该物种表现出颜色偏好，并且有色诱捕器可能有助于在有野生动物出没且有人到访的自然区域监测和控制这种叮咬性外寄生虫。
