Since a standardised guideline for soil mites was not available in the past, an international working group developed a soil ecotoxicity test with the gamasid mite Hypoaspis aculeifer. 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.

It can be used for water soluble or When refining endpoints obtained by Collembola OECD 232 and Hypoaspis OECD 226 reproduction tests risk assessors are two reproduction tests with H. aculeifer were performed using copper To assess whether the juvenile life stages are the most susceptible, we examined the acute toxicity of dimethoate on larvae, protonymphs, deutonymphs, males, and females of H. aculeifer. The mites were exposed to 0, 2, 4, and 6 mg dimethoate kg-1 for 7 days in an OECD artificial soil (5% organic matter).
