The globally distributed arbovirus West Nile virus (WNV) is expanding across Europe, with rising numbers of human cases and an increasingly broad geographic distribution. Transmitted primarily by Culex mosquitoes, WNV lineages 1 and 2 are pathogenic to humans, yet their differences in transmission dynamics remain unclear. As vertebrate hosts develop varying viremia, mosquitoes encounter a...

Mosquitoes host a wide diversity of insect-specific viruses alongside medically important arboviruses. While insect-specific viruses have been proposed as potential modulators of arbovirus transmission, the mechanisms underlying these interactions remain poorly understood, particularly in the context of persistent infections (long-term infection without clearance) that characterise most...

Bluetongue virus (BTV), Schmallenberg virus (SBV) and epizootic haemorrhagic disease virus (EHDV) are arthropod-borne viruses transmitted by biting midges and primarily affect domestic and wild ruminants. In Central Europe, the importance of biting midges as vectors increased after the emergence of BTV-8 in 2006 and SBV in 2011. Furthermore, in 2022, EHDV was detected for the first time in...

Bluetongue virus (BTV) is the causative agent of a major livestock disease and it is transmitted by Culicoides biting midges between the ruminant hosts. The first recorded outbreak in Central Europe was caused in 2006/2007 by serotype BTV-8, leading to a major epidemic. In 2023, serotype BTV-3 emerged in the Netherlands and spread rapidly to neighbouring countries. Compared to the BTV-8...

Accurate species identification of biting midges (Diptera: Ceratopogonidae) is essential for understanding pathogen transmission dynamics and developing effective vector control strategies. Traditional morphological identification is challenging and in many cases impossible due to the occurrence of cryptic species. Although sequencing of the mitochondrial cytochrome c oxidase subunit I (COI)...

Mosquitoes are important vectors of arboviruses but also harbour insect-specific viruses (ISVs), which replicate exclusively in insects. Although numerous ISVs have been identified, little is known about their interactions with arboviruses and mosquito hosts. ISVs closely related to arboviruses have been suggested to interfere with arbovirus replication, making them potential tools for vector...
