Silencing IDH decreased walking activity but increased foraging success in O. formosanus. (A) Behavioral apparatus (1, camera; 2, testing arena). Four pieces of food patches as food zones were positioned on the different 4 directions (0°, 90°, 180°, and 270° clockwise) of the inner ring. (B) Foraging trajectories of dsIDH-injected (deep green color) and dsGFP-injected (deep blue color) workers. (C) Distance moved, (D) velocity, (E) requency in food zones, and (F) cumulative time in food zones of dsIDH-injected and dsGFP-injected workers (N = 10 samples/treatment, 10 termites/sample). The data are presented as mean ± SEM. Independent t-test, ^*P < 0.05. ^#0.05 ≤ P < 0.1.
