The effect of ivermectin treatment of cattle on the attractiveness of dung to scarabaeid dung beetles was assessed by pitfall trapping in Denmark, Tanzania and Zimbabwe. Traps were baited with dung collected at intervals after heifers were treated with ivermectin by subcutaneous injection (0.2 mg kg-1 body weight). In one Danish trial, beetles preferred control dung from untreated cattle, whereas no preference was found in two other experiments. In Tanzania, the overall tendency for beetles was also to prefer control dung. In Zimbabwe, two species (Euoniticellus intermedius and Liatongus militaris) were particularly attracted to dung from treated cattle, whereas three others did not discriminate between dung types. It is concluded that at least in some cases the attractiveness of cattle dung to scarabaeid beetles is affected by avermectin therapy. Beetle discrimination between dung types is probably attributable to some unknown side effect of the treatment rather than being a direct response to the drug itself.
通过在丹麦、坦桑尼亚和津巴布韦设置陷阱诱捕，评估了伊维菌素治疗牛对粪金龟科蜣螂粪便吸引力的影响。陷阱用皮下注射伊维菌素（0.2毫克/千克体重）处理后的小母牛在不同时间收集的粪便作为诱饵。在丹麦的一项试验中，甲虫更喜欢未处理牛的对照粪便，而在其他两项实验中未发现偏好。在坦桑尼亚，甲虫的总体趋势也是更喜欢对照粪便。在津巴布韦，两种物种（中间真地鳖和军地鳖）特别被处理后牛的粪便所吸引，而其他三种则没有区分粪便类型。得出的结论是，至少在某些情况下，牛粪对粪金龟科甲虫的吸引力受到阿维菌素治疗的影响。甲虫对不同类型粪便的区分可能归因于治疗的一些未知副作用，而不是对药物本身的直接反应。
