It is often difficult to compare studies examining the effects of endectocides on dung fauna because of different experimental approaches, for example, active ingredients (eprinomectin, doramectin, ivermectin, moxidectin) and formulations (injectable, pour‐on, spiked). To gain a better understanding, we performed a quantitative meta‐analysis using 22 studies to assess the overall effect of endectocide residues on the occurrence (presence or absence) and abundance of aphodiine dung beetles. Our results document a positive effect on the occurrence of adult beetles, indicating that adults tend to be attracted to dung with residues. Conversely, larvae are less likely to occur in the presence of residues. Thus, either adults that colonize dung with residues do not lay eggs or, more likely, the larvae that hatch from these eggs die early in development. Abundance of adult and larval stages was shown to be significantly reduced in dung containing residues. When individual endectocides were compared, only ivermectin demonstrated a significantly negative effect on the abundance of both adults and larvae, possibly owing to a small sample size for other agents. In laboratory studies, only dung “spiked” with endectocides reduced the abundance of larvae, whereas during field research, only pour‐on applications were shown to reduce the abundance of larvae. The present study further documents the nontarget effects of endectocide residues on dung‐dwelling organisms, provides robust evidence on the consequences of different application methods, and emphasizes the need for standardized methodological techniques in future studies.

内毒素残留对Aphodiine甲虫存活的影响:一项荟萃分析

由于不同的实验方法,例如活性成分(依普诺菌素,多拉克丁,伊维菌素,莫昔克丁)和制剂(注射剂,泼洒剂,加标针剂),通常很难比较研究检查内生杀菌剂对粪便动物的影响的研究。为了获得更好的理解,我们使用22项研究进行了定量荟萃分析,以评估内杀菌剂残留对双膦二甲et的发生(有无)和丰度的总体影响。我们的结果证明对成年甲虫的发生有积极影响,表明成年甲虫容易被粪便吸引。相反,在残基存在下幼虫发生的可能性较小。因此,用残渣定居在粪便中的成虫不会产卵,或者更可能的是,从这些卵中孵出的幼虫在发育的早期死亡。含有粪便的残渣显示成年和幼虫阶段的丰度显着降低。当比较各个内生杀菌剂时,仅伊维菌素对成年和幼虫的丰度显示出显着的负面影响,这可能是由于其他药物的样本量较小所致。在实验室研究中,仅粪便中掺有内生杀虫剂的粪便可减少幼虫的丰度,而在田间研究中,仅泼洒粪便可减少幼虫的丰度。本研究进一步记录了内毒素残留对粪便生物的非目标作用,为不同施用方法的后果提供了有力的证据,并强调在未来的研究中需要标准化的方法学技术。只有伊维菌素对成年和幼虫的丰度显示出显着的负面影响,这可能是由于其他药物的样本量较小所致。在实验室研究中,仅粪便中掺有内生杀虫剂的粪便可减少幼虫的丰度,而在田间研究中,仅泼洒粪便可减少幼虫的丰度。本研究进一步记录了内毒素残留对粪便生物的非目标作用,为不同施用方法的后果提供了有力的证据,并强调在未来的研究中需要标准化的方法学技术。只有伊维菌素对成年和幼虫的丰度显示出显着的负面影响,这可能是由于其他药物的样本量较小所致。在实验室研究中,仅粪便中掺有内生杀虫剂的粪便可减少幼虫的丰度,而在田间研究中,仅泼洒粪便可减少幼虫的丰度。本研究进一步记录了内毒素残留对粪便生物的非目标作用,为不同施用方法的后果提供了有力的证据,并强调在未来的研究中需要标准化的方法学技术。仅粪便中掺有内生杀虫剂的粪便会降低幼虫的丰度,而在田间研究中,只有泼洒粪便才能减少幼虫的丰度。本研究进一步记录了内毒素残留对粪便生物的非目标作用,为不同施用方法的后果提供了有力的证据,并强调在未来的研究中需要标准化的方法学技术。仅粪便中掺有内生杀虫剂的粪便会降低幼虫的丰度,而在田间研究中,只有泼洒粪便才能减少幼虫的丰度。本研究进一步记录了内毒素残留对粪便生物的非目标作用,为不同施用方法的后果提供了有力的证据,并强调在未来的研究中需要标准化的方法学技术。环境毒性化学2020; 39:863-872。©2020 SETAC
