Pesticides are a major concern because of their deleterious impacts on biodiversity and on the ecological functions provided by living organisms. Although earthworms are well studied, smaller-sized organisms, such as Collembola, also contribute to the agroecosystem functioning, and their sensitivity to pesticides makes them good bioindicators of soil quality. Using data from 21 publications, we performed a meta-analysis to compare the pesticide sensitivity of Collembola with other soil invertebrate groups and discuss the relevance of including tests on representatives of this microarthropods group in European regulation tests. We defined a paired observation as the median lethal concentration or the median effect concentration values for both Collembola species and another soil fauna group (Acari, enchytraeids, earthworms, isopods, and nematodes) under a unique combination of author, year, substance, and type of soil (61 and 57 paired observations for reproduction and lethal effects). In some studies, paired comparisons were available for several groups of soil fauna. We demonstrated that Collembola are among the most sensitive soil fauna groups to a variety of pesticides, notably for effects on reproduction, mostly compared with earthworms and enchytraeids. Because there are several modes of exposure and explaining factors, we suggest moving from a single-species study to a food-chain approach integrating different taxonomic groups. Differences between soil fauna groups in sensitivity or response to pesticides could have effects on soil communities and also on soil functions.

由于农药对生物多样性和生物提供的生态功能具有有害影响，因此它们是一个主要关注点。尽管蚯蚓的研究已经很充分，但体型较小的生物，如弹尾目昆虫，也有助于农业生态系统的运作，而且它们对农药的敏感性使它们成为土壤质量的良好生物指标。我们使用来自 21 篇出版物的数据进行了荟萃分析，以比较弹尾目昆虫对农药的敏感性与其他土壤无脊椎动物群，并讨论在欧洲法规测试中包括对该微节肢动物组代表进行测试的相关性。我们将配对观察定义为两种弹尾目物种和另一种土壤动物群（蜱螨目、线蚓、蚯蚓、等足目和线虫）在作者、年份、物质和土壤类型的独特组合下的半数致死浓度或半数效应浓度值（61 和 57 对观察用于繁殖和致死效应）。在一些研究中，几个土壤动物群的配对比较是可用的。我们证明，弹尾目昆虫是对各种农药最敏感的土壤动物群之一，尤其是对繁殖的影响，与蚯蚓和线蚓相比，主要是对繁殖的影响。由于存在多种暴露方式和解释因素，我们建议从单一物种研究转向食物链方法，整合不同的分类群。对农药的敏感性或反应存在差异的土壤动物群可能对土壤群落产生影响，也可能对土壤功能产生影响。环境毒理化学 2022；41：2333-2341。©2022 作者。环境毒理化学由 Wiley 期刊代表 SETAC 出版。
