Cold tolerance (CT) of Ae. aegypti and Ae. albopictus eggs. Mean survivorship (normalized to 25 °C controls, in %) after exposure of Ae. aegypti eggs to 0 °C and 3 °C for a maximum of 9 days in experiment CT1 (a), and eggs of both species to 0 °C (b), − 2 °C (c) and − 6 °C (d) for a maximum of 8 days in experiment CT2. In addition, the global (shared) CT model is shown (d). Mean unnormalized survivorship of controls CT1: 47.8–51.1%; CT2: Ae. aegypti: 50.5–51.3%; Ae. albopictus: 52.7–53.6% (raw data of treatments in Additional file 2: Table S1)
