Dataset for: Toxicity of neonicotinoids to Folsomia candida and Eisenia andrei

In this paper we compared the toxicity of the neonicotinoids imidacloprid, thiacloprid, thiamethoxam, acetamiprid and clothianidin to the survival and reproduction of two species of soil invertebrates: Folsomia candida and Eisenia andrei. Tests were performed using LUFA 2.2 natural soil, following standard protocols aimed at answering two questions: (i) Is there a difference in the toxicity between pure compound and its formulation? (ii) Is there a difference in the sensitivity of the species exposed to the same compound? Formulations and pure compounds presented similar toxicity to both endpoints tested for E. andrei. For F. candida, acetamiprid and imidacloprid presented different toxicity, with the first being four times more toxic to survival (LC50 0.12 mg a.s./kg dry soil and the latter, four times more toxic to the reproduction of the springtail (EC50 0.25 mg a.s./kg dry soil) than their commercial formulation. The most toxic compound to E. andrei was acetamiprid (LC50 0.80 and EC50 0.35-0.40 mg a.s./kg), and for F. candida clothianidin (LC50 0.07 and EC50 0.05 mg a.s./kg). Estimated risk ratios indicated that only one application per year of clothianidin in the formulation Poncho® may pose a threat to the populations of springtails and earthworms.

本文对比了拟除虫菊酯类杀虫剂咪鲜胺、噻虫嗪、噻虫胺、乙基多杀菌素和氯虫苯甲酰胺对两种土壤无脊椎动物——拟谷盗Folsomia candida和红worm Eisenia andrei的生存和繁殖毒性。实验采用LUFA 2.2天然土壤进行，遵循旨在解答两个问题的标准实验规程：（一）纯化合物与其制剂在毒性上是否存在差异？（二）暴露于相同化合物的物种敏感性是否存在差异？对于E. andrei，制剂和纯化合物在测试的两个终点上表现出相似的毒性。对于F. candida，乙基多杀菌素和咪鲜胺显示出不同的毒性，前者对生存的毒性是后者的四倍（LC50 0.12 mg a.s./kg干土壤，后者对跳蚤的繁殖毒性是后者的四倍，EC50 0.25 mg a.s./kg干土壤，相较于其商业制剂）。对E. andrei毒性最大的化合物是乙基多杀菌素（LC50 0.80和EC50 0.35-0.40 mg a.s./kg），而对F. candida毒性最大的是氯虫苯甲酰胺（LC50 0.07和EC50 0.05 mg a.s./kg）。估算的风险比表明，每年对Poncho®制剂中的氯虫苯甲酰胺仅使用一次，可能对跳蚤和红worm种群构成威胁。
