Figure 2. Soluble hexamerin concentrations measured by immunodiffusion in soft tissue/hemolymph extracts of abdomens of females (A) and males (B) of Manduca sexta at three times after eclosion. The concentrations of each antigen are expressed as percentages of those in extracts of female pupae. Values for males are plotted on an expanded scale in the inset. Error bars show standard errors; n = 6 in each case. Values for day-1 males relative to those of male pupae are indicated in the text.
