Overview
- In late July mosquito numbers surged after heavy rain followed by heat, and IFABET urged combined source reduction and insecticide-free trapping to cut tiger-mosquito populations quickly.
- Native Culex mosquitoes that carry West Nile virus have expanded beyond Berlin and Brandenburg into Saxony, Saxony-Anhalt and Thuringia, increasing local infection risk for people, especially the elderly and immunocompromised.
- Genetic tests have found growing pyrethroid resistance in European tiger-mosquito populations, and INTERFACE models show warming could make parts of Central Europe more suitable for chikungunya transmission.
- Laboratory research from the University of Maryland and the Cary Institute found leaf litter from certain invasive street trees helps mosquito larvae survive and grow faster, a pattern linked to lower-income neighborhoods with more neglected lots.
- Authorities and scientists are moving away from sole reliance on chemical spraying toward integrated, community-driven measures that combine public surveillance programs like the Mückenatlas, targeted monitoring by institutes, and local habitat cleanup to reduce human bites and disease risk.
