Hypoaspis aculeifer is a widespread predatory mite in soil ecosystems, feeding on Enchytraeids, Collembola, other Mites and Nematodes. Its ecological importance in agriculture is the potential to regulate plant parasitic nematodes. It is worldwide distributed and can easily be collected and reared in the laboratory.

This paper outlines the guideline development process and the principles of the protocol, and presents the results of an international ring test from which the validity criteria for the final guideline were derived. The standardized bioassay using the predatory mite Hypoaspis aculeifer (TG 226; as reported by OECD 2008) has already proven its usefulness for the assessment of chemicals. While included in the regulatory assessment scheme of pesticides as a non-target arthropod, it has still been rarely used for the assessment of soils or complex matrices of unknown quality. For such an objective, the 2015-09-01 · The reproduction of enchytraeids (Enchytraeus bigeminus) and predatory mites (Hypoaspis aculeifer) was studied using standard laboratory tests according to OECD guidelines 220 (2004) and 226 (2008). The number of juveniles of E. bigeminus was reduced at several plots with high concentrations of Cd or Cu (the latter in combination with low pH values). Hypoaspis (Geolaelaps) aculeifer est considéré comme dûment représentatif de la faune du sol, et des acariens prédateurs en particulier.
