Fig. 2. Hemolymph ecdysteroid titers in a single larva (filled circles) and ecdysteroid secretion by a single set of thorax and abdomen (bars) at different times during A. aegypti fourth larval stadium and in 12 h old pupae (P). Each point or bar represents least square means ± s.e.m.; N=27. For ecdysteroid secretion values, columns with different letters are significantly different from each other (Tukey–Kramer HSD, P≥0.05). NM, newly molted fourth instars never given access to food.
