摘要

Culicoides叮咬蠓(双翅目:Ceratopogonidae)是多种具有兽医和医学重要性的虫媒病毒以及鸟类血孢子虫寄生虫的已知载体。尽管Culicoides是重要的传播媒介,但其在非农田栖息地的分布情况在很大程度上仍不为人所知。我们进行了一项研究,以评估西班牙北部城市生态系统中咬蠓的物种群落组成、数量和宿主取食模式。在 6 个月的时间里,我们每两周在 6 个城市景观(3 个墓地和 3 个绿地)中进行一次光诱吸式诱捕。经形态鉴定,共发现 18 个种类的 181 头蚋标本,其中以 Obsoletus 复合体为主(占总捕获量的 43.%),其次是 Culicoides kibunensis(21.5%)。6 月初绿地和 5 月墓地的蠓虫高峰期。寄主取食模式显示,有四种库里科蠓偏爱鸟类(主要是土拨鼠属)。尽管采集到的标本数量较少,但记录到的咬蠓种类却非常多样。这些发现提供了有关城市环境中啮齿类动物生态学及其与宿主相互作用的重要见解,对于疾病监测和管理策略至关重要。

Culicoides biting midges in urban areas of northern Spain.

Culicoides biting midges (Diptera: Ceratopogonidae) are known vectors of multiple arboviruses of veterinary and medical importance, as well as avian haemosporidian parasites. Despite their significant role as vectors, the distribution of Culicoides species in non-farmland habitats remains largely unknown. We conducted a study to assess the species community composition, abundance, and host feeding patterns of Culicoides biting midges in urban ecosystems in northern Spain. Light-baited suction traps were operated biweekly for 6 months across six urban landscapes (three cemeteries and three green areas). In total, 181 Culicoides specimens of 18 species were morphologically identified, with the Obsoletus complex being predominant (43.% of the total catches), followed by Culicoides kibunensis (21.5%). Culicoides midges peaked in early June in green areas and in May in cemeteries. Host feeding patterns revealed avian preferences (mainly Turdus spp.) in four Culicoides species. Despite the low overall number of specimens collected, a high diversity of biting midge species was recorded. These findings offer critical insights into Culicoides ecology and their interactions with hosts in urban settings, which are vital for disease surveillance and management strategies.

期刊介绍: Medical and Veterinary Entomology is the leading periodical in its field. The Journal covers the biology and control of insects, ticks, mites and other arthropods of medical and veterinary importance. The main strengths of the Journal lie in the fields of: -epidemiology and transmission of vector-borne pathogens changes in vector distribution that have impact on the pathogen transmission- arthropod behaviour and ecology- novel, field evaluated, approaches to biological and chemical control methods- host arthropod interactions. Please note that we do not consider submissions in forensic entomology.
