Research Topics

The research group "Arbovirus Ecology" studies the spatial-temporal distribution of vectors and associated pathogens.

Vector and arbovirus surveillance

Human and animal diseases caused by arthropod-borne viruses (arboviruses) are of growing importance in many countries of the world. Continuing eco-climatic changes and globalization create suitable conditions for the emergence of arboviruses. Thus, we are involved in different international and national programs to collect and analyse vector and arbovirus data. This provided a solid base to determine the underlying causes of the seasonal fluctuations in arbovirus activity and arbovirus emergence.

Vector collection and screening

We conduct mosquito, sandfly, tick and biting midge collections in different setting in Euoprean and international settings. This data are used 1) to understand the distribution, diversity and phenology of the different vector species and 2) for arbovirus screening.

Dead-bird surveillance

Usutu virus and West Nile virus are threats for human and animal health. In cooperation with the Nature and Biodiversity Consveration Union (NABU) we ask citizens in Germany to sent dead birds to our institute. The samples are screened for arboviruses to understand the spatial-temporal circulation in Germany.

Risk modelling of spatial-temporal arbovirus transmission

Ecology and host-feeding patterns of vectors

The fundamental understanding of vector ecology is the sine qua non to understand the spatial-temporal risk of pathogen transmission.

Especially host-feeding patterns of blood-sucking arthropods shape the transmission cycle of vector-borne patghoesn, which direct insights into the interaction between vectors and hosts. However, there is still a lack of knowledge about the host spectrum for vector species, including mosquitoes, biting midges or sandflies.

Methods for vector sampling and identification

Standardized techniques for vector sampling and identification are crucial to allow comparable data collection and subsequent analysis. We compare different traps for host-seeking and resting mosquitoes (e.g. Lühken et al. 2014, Sauer et al. 2020) or evalute subsampling methods for large mosquito samples (Jaworski et al. 2019). For vector identification, we develop both, molecular and morphometric tools, which also allow the identification of cryptic species (e.g. Culex pipiens pipiens vs. Culex torrentium or members of the Anopheles maculipennis complex) (e.g. Börstler et al. 2014, Lühken et al. 2016, Sauer et al. 2020).

Third-Party Funded Projects

Near-real time decision tool to response against emerging mosquito-borne diseases (NEED) [2020-2025]

Mosquito-borne viruses are an emerging threat in Central Europe, which are a major challenge for researchers, stakeholders and the overall health care system for humans and animals. Thus, there is an urgent need to develop an evidence-based decision tool helping to select a cost-effective reaction to the local transmission risk. These responses can be very different, e.g. surveillance strategies, vector control or vaccination, which are all associated with different costs and outcomes regarding pathogen control. Therefore, the objective of the here proposed project is the development of a ‘Near-real time decision tool to response against emerging mosquito-borne diseases’. Due to the quickly changing spatial-temporal pattern regarding emerging and re-emerging mosquito-borne viruses, model results are updated near-real time by combining remotely available biotic and abiotic data with statistical models. The results are presented in a rapidly updated website, which provide different modelling products showing the spatial-temporal distribution of mosquito vectors and risk of introduction/transmission of associated viruses. The combination with estimates on the costs for different response scenarios will inform a decision tool, allowing the selection of cost-effective measurements for detection, prevention and control of mosquito-borne viruses.

Diversity components in mosquito-borne diseases in face of climate change (DiMoC) [2020-2023]

DiMoC will contribute to better understand the effects of biodiversity in mosquito-borne pathogen transmission. Through the analysis of different organisational (hosts, insects, viruses, human population), spatial (continental, regional, local, organism) and temporal scales (current conditions / future projections), DiMoC will test whether:

1. Greater diversity in insect-specific virus hosted by mosquitoes results in a reduced relative risk of transmission of a virus through interactions within these populations;

2. Mosquito diversity is influenced by interspecific interactions (e.g. competition) between species, which translates into different relative transmission risk;

3. Greater host species diversity reduces the transmission risk due to the dilution effect;

4. Changes in climatic conditions explain current large-scale patterns of pathogen, vector, and host diversity more than socio-economic conditions;

These results will allow to evaluate whether scenarios and models including climate, landscape diversity, and societal diversity can be used to quantify uncertainty in future trends of risks in pathogen transmission.

Mosquitoes and mosquito-borne zoonoses in Germany (CuliFo2) [2019-2022]

Early Warning System for Mosquito-borne Diseases (EWSMD) [2018-2021]

In this project, we will use the entomological, epidemiological, climatological and geographical data from Germany and Greece already available and/or to be produced by our partners, key actors in the field of pathogen detection and vector control in Europe, in order to develop a common Early Warning System for mosquito borne diseases to be implemented and evaluated in both countries. Substantial exchange of know-how and expertise will take place between two major research institutes in the field arbovirology and transfer to two Major mosquito control operators in Europe for operational purposes.
The project's objectives are: 1. Connecting major European actors in arbovirology and mosquito surveillance and control from Germany and Greece 2. Reanalyze the epidemiological data from the severe WNV epidemic in Northern Greece since 2010 and the USUV outbreaks in Germany since 2011 so as to prepare accordingly Germany and Greece against WNV, USUV and other arboviruses. 3. Identify high risk areas and critical time intervals for WNV and USUV circulation following modeling from entomological data and epidemiological data already produced by the partners during the last years and to be further developed for the years 2018 and 2019 (Lühken et al. 2017). 4. Provide good practices, innovative tools and methods for the control of container-breeding mosquitoes in urban settings, with special consideration of Culex pipiens and Aedes albopictus, which are the major European vectors for existing (USUV in Germany and WNV in Greece) and/or threatening (WNV for Germany, dengue, Chikungunya and Zika for both countries) mosquito-borne diseases. 5. Produce, update and make available this information to concerned Public Health Institutions and/or other bodies of both countries, a functional webGIS, in which the users will have the possibility to view, explore, query, and display the periodical risk maps of the Early Warning System for mosquito-borne diseases.
