As expected, all tested life history parameters of the Asian bush mosquito depended strongly on ambient temperature. The minimum thermal temperature for development of the Asian bush mosquito from the first-instar to adult collected in USA was calculated between 12.6 °C (females) and 9.4 °C (males; ) while our estimates yielded 7 °C as the lower threshold of developmental temperature. Differences may be explained with differently used regression methods while a biological explanation maybe post-invasive local adaptation or a different origin of the respective invasive populations. The optimum temperature presented here matches the optimal temperature known for laboratory rearing of this species (25 °C; [47, 48]). The upper threshold lies between 28 °C and 34 °C for a North American population . This range covers the upper-temperature threshold for development calculated here. At present, the Asian bush mosquito occurs in places with mean monthly temperatures between -2.7 °C and 11.0 °C in Germany . Here, we show that individuals exposed to constant ambient temperatures between 10 °C and 31 °C reach the adult stage, while larvae cannot survive 0 °C and 5 °C.
