vitellogenin expression in head tissue of adult female and adult male N. vespilloides across five behavioural states. (a) vg1 expression and (b) vg2 expression significantly decreases during active care of larvae in females. (c) vg1 expression and (d) vg2 expression decreases in males during care of larvae but the reduction in expression is only statistically significant for vg1. Bars represent mean relative quantity and error bars represent±1 s.e.m. Bars with different letters are statistically significantly different in pairwise comparisons. Expression was measured from whole heads using 10 individuals per behavioural state.
