Fig. 1. Impacts of temperature and juvenile hormone (JH) on soldier caste differentiation. Results shown represent cumulative presoldier formation on day 15 of assays that were conducted under four different conditions of 22° and 27°C, with and without ectopic JH. Two colonies were tested at three different times over a 1-year period. Bars with the same letter within the colony are not significantly different by non-parametric Kruskal–Wallis tests (P<0.05, N=3).
