Mosquito Collection

In all four country locations mosquito collection via Ovitraps, Aspirators and Sentinel Traps has started.

• In Germany, we put up 149 Ovitraps in three collection rounds (June, July, August 2023) along the A5/ A61 motorway. So far we have detected Aedes albopictus mainly north of Basel on the A5. The exact evaluation is still in progress. We will compare the data sets with 2011-2017 and 2022 data. In addition, qualitative research has been conducted in spring/summer 2023 in the Heidelberg area.
• In India, fieldwork started along the Chennai-Tiruchirappalli route. Using ovitraps for eggs, BG- sentinel traps and aspirators for adults mosquito specimen were collected on buses, trains and larvae collection happened in houses. Entomological and genomic analysis is ongoing. Qualitative interviews and go-alongs have been conducted on stations and in port infrastructure.
