A study examining the relationship between social interactions and JH titers in termites (Watanabe et al., 2011). (A) Experimental designs to obtain workers (white arrowheads) under the absence/presence of soldiers (black arrowhead) put on petri dishes with filter papers containing JHIII. The JH titers of workers reared by this method were quantified along the time course. (B) JH-titer transitions in workers during the soldier induction experiment. (C) Induction rates of presoldier differentiation under the absence/presence of soldiers. The gray shading indicates the range of soldier ratio observed in nature.
