Our laboratory experiments contribute to our understanding of mosquito thermal biology, which determines ecological and epidemiological features such as invasion success of a disease vector. The Asian bush mosquito can develop to female adults in temperatures ranging from 7 °C to 31 °C. Albeit the higher temperature limits of the species are not reached in Germany on a mean monthly basis, lower temperature limits of eggs and larvae seem to determine the species’ distribution. Also, we present temperature-dependent life trait data.
