Reductions were observed for coprophagous flies, parasitic wasps, and both predaceous and coprophagous beetles. The species most affected were the flies, Sepsis sp. and Coproica mitchelli , eucoilid wasps, and the beetles, Cercyon quisquilius and C. pygmaeus . These results were consistent both within and between years. Dung treated with ivermectin had not appreciably degraded after 340 days in the field. Reduced insect activity may subsequently inhibit the degradation of dung voided by these animals.
