Abstract

Climate-change induced weather extremes like floods are increasing in frequency and intensity, with potential consequences for disease vector ecology. We report on a flooding event during the winter of 2023/2024 in Hanover city, Germany. Our observations demonstrate that I. ricinus, the most important vector of tick-borne diseases in Europe, can survive prolonged periods under water and quickly resume host-seeking activity once conditions normalize. Despite being submerged for a total of 25 days, nymphal and adult ticks were observed questing four weeks of the water receding, with densities comparable to pre-flood levels. These findings underscore the resilience of I. ricinus and highlight the potential of ticks to pose infection risks even after extreme weather events.

蓖麻虱在洪水中幸存下来

气候变化导致洪水等极端天气的发生频率和强度不断增加，可能对病媒生态造成影响。我们报告了德国汉诺威市 2023/2024 年冬季的一次洪水事件。我们的观察结果表明，蓖麻蜱是欧洲最重要的蜱媒疾病病媒，它能在水中存活很长时间，并在条件恢复正常后迅速恢复寻找宿主的活动。尽管蓖麻蜱被水淹没了25天，但在水退去四周后，仍能观察到若虫和成蜱在寻找宿主，其密度与洪水前的水平相当。这些发现凸显了蓖麻蜱的恢复能力，并强调了蜱虫即使在极端天气事件后仍有可能造成感染风险。

期刊介绍： Ticks and Tick-borne Diseases is an international, peer-reviewed scientific journal. It publishes original research papers, short communications, state-of-the-art mini-reviews, letters to the editor, clinical-case studies, announcements of pertinent international meetings, and editorials. The journal covers a broad spectrum and brings together various disciplines, for example, zoology, microbiology, molecular biology, genetics, mathematical modelling, veterinary and human medicine. Multidisciplinary approaches and the use of conventional and novel methods/methodologies (in the field and in the laboratory) are crucial for deeper understanding of the natural processes and human behaviour/activities that result in human or animal diseases and in economic effects of ticks and tick-borne pathogens. Such understanding is essential for management of tick populations and tick-borne diseases in an effective and environmentally acceptable manner.
