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).
