Survival of adult mosquitoes after exposure to low subzero temperature.

Adult male Ae. albopictus (A) and female Ae. aegypti and Cx. quinquefasciatus (B) were transferred from room temperature to -15 oC with (right of A and B) or without water (left of A and B). Adult mosquitoes were removed (at 1-h interval for mosquitoes exposing with water or at 1- or 2-min interval for mosquitoes exposing without water) from subzero temperature and recovered under normal rearing condition until 100% mortality were reached. N = 3 groups of 20 adult mosquitoes for each data point.
