  1. 402. Temperature-driven mortality in Aedes aegypti and its role in modulating dengue outbreaks: an ecological time-series analysis

    Oral presentation

    Background: Temperature influences dengue transmission, but the direction and magnitude of extreme heat effects on vector populations remain unclear. This study quantifies how cumulative heat-induced mortality in adult Aedes aegypti contributes to dengue incidence under real conditions, adopting a One Health perspective linking climate variability, vector biology, and human disease...

  2. 466. An experimental field approach to study climate warming effects on container-breeding mosquitoes

    Vectors
    Oral presentation

    Climate change and urbanization facilitate the spread of container-breeding mosquitoes, increasing the risk of mosquito-borne disease outbreaks in previously unaffected regions. However, most knowledge of mosquito thermal biology is based on laboratory studies. Here, we present the first results of a novel field experiment assessing climate warming effects on urban mosquito populations. Using...

  3. 391. Human presence shapes mosquito community composition and virus abundance in a Savannah ecosystem

    Oral presentation

    Anthropogenic land-use change reshapes mosquito communities with implications for arbovirus ecology. However, joint assessments of mosquito and virus communities across land-use types remain rare, particularly in African savannah ecosystems. We characterized both communities along an anthropogenic disturbance gradient in the Kavango Zambezi Transfrontier Conservation Area in Namibia.
    In 2023,...

  4. 446. Behavioral Plasticity in Ixodes ricinus: Linking Energy Reserves to Host-Seeking Activity and Infection Transmission Potential
    Paula Hornauer (Stiftung Tierärztliche Hochschule Hannover)

    Vectors
    Oral presentation

    The seasonal dynamics of tick-host interactions are critical for the transmission of vector-borne pathogens, yet the physiological drivers of behavioral plasticity in Ixodes ricinus remain poorly understood. In this study, we investigated how seasonal changes in energy reserves influence host-seeking behavior and infection transmission potential. Monthly flagging of I. ricinus across a...

  5. 396. Hidden interactions in ticks: Co-infection patterns of Borrelia spp. as indicators of TBEV microfoci
    Katrin Fachet-Lehmann (University of Hohenheim, Department of Parasitology, Stuttgart)
    10/5/26, 3:00 PM
    Vectors
    Oral presentation

    The ecological mechanisms underlying the spatial restriction of tick-borne encephalitis virus (TBEV) foci remain poorly understood. As Ixodes ricinus frequently carries multiple pathogens, interactions between Borrelia spp. and TBEV may contribute to focal virus persistence. Therefore, co-infection patterns and Borrelia species composition were investigated in relation to TBEV, in...

  6. 412. The Role of Raccoons in Tick-Borne Disease Ecology
    Alexander Lindau (University of Hohenheim, Department of Parasitology)
    10/5/26, 3:15 PM
    Vectors
    Oral presentation

    Understanding the contribution of wildlife species to the maintenance and spread of zoonotic pathogens is a key component of the One Health concept. However, the role of raccoons in the epidemiology of tick-borne encephalitis virus (TBEV) has remained unexplored. In this study, raccoons from Baden-Wuerttemberg, one of the main endemic TBE areas in Germany, were screened for TBEV infections...
