In contrast, faeces voided by cattle treated with a pour-on formulation of eprinomectin were associated with high juvenile mortality during the first 1{\textendash}2 weeks after treatment. Increased mortality also occurred among newly emerged beetles fed on faeces collected 3 days after eprinomectin treatment and there was evidence of suppressed brood production among those that survived. This effect was still apparent even after insects fed for a further 10 days on the faeces of untreated cattle. A model simulating the effects of drug residues on dung beetle populations suggests that in the absence of immigration a single treatment of eprinomectin is capable of reducing beetle activity in the next generation by 25{\textendash}35\%. Effects are likely to be greatest when treatment coincides with emergence of a new generation of beetles.}, keywords = {Dung beetles, eprinomectin, Modelling, moxidectin, Pour-on formulations}, author = {Wardhaugh, Keith G. and Longstaff, B.
