Minimum survival temperature of Aedes eggs after cold treatment. Minimum survival temperature in comparison to duration of treatment for European eggs which have undergone a diapause and non-diapausing eggs of Ae. albopictus and tropical eggs of Ae. albopictus and Ae. aegypti. Eggs of European Ae. albopictus which passed through a diapause survive lower minimum temperatures than non-diapausing eggs when exposed for more than 12h, whereas no differences occurred for short exposure (1h). Eggs of tropical Ae. albopictus survive lower minimum temperatures than Ae. aegypti eggs when exposed for 1h, whereas no differences occurred for longer exposure (>8h).
