Ivermectin was added to cattle dung in controlled concentrations like those found in the pats of injected cattle, and the medium was used to rear larvae of the dung fly Scatophaga stercoraria. Ivermectin at 0.036 ppm (wt/wet weight) debilitates 50% of the larvae within 48 h. At 0.015 ppm, 50% of the larvae are unable to pupariate, while at 0.001 ppm, 50% of the larvae fail to reach the adult stage. Adults produced from larvae reared in pats containing 0.0005 ppm ivermectin show high levels of fluctuating asymmetry in wing characteristics as well as deformities in the wing veins themselves. The data are discussed in relation to the effects of excreted ivermectin on pastureland biology.
