Fig. 5. Polyol and sugar content of nondiapausing and diapausing adult females of Culex pipiens. (A) Sorbitol; (B) glycerol; (C) trehalose; (D) total sugars. Closed squares, ND25 mosquitoes, reared under a nondiapausing photoperiod (15 h:9 h, L:D) at 25°C; open squares, ND18 mosquitoes, reared under a nondiapausing photoperiod at 18°C; closed diamonds, D18 mosquitoes, reared under a diapausing photoperiod (9 h:15 h, L:D) at 18°C; open diamonds, D18 to ND25 at 40 days. Values are means ± s.e.m. of 10 replicates of five individuals each. All error bars are smaller than the symbols.
