From: Low doses of ivermectin cause sensory and locomotor disorders in dung beetles
Ivermectin alters the foraging behaviour of Scarabaeus cicatricosus.
Mean (±s.e.m.) data showing the negative effects of different ivermectin doses on the time required to detect and arrive at a food resource. Six concentrations of 1.0, 3.3, 10.0, 33.3, 100.0 and 200.0 μg kg–1 dung (fresh weight) plus an untreated control were used. Red dots indicate the time required for 25% of individuals to arrive (t25%; 5 individuals); blue dots correspond to the time required for 50% of individuals to arrive (t50%; 10 individuals) (data are means ± s.e.m.; *P < 0.05, **P < 0.01, ***P < 0.001, post-hoc Dunnet’s test).
