OECD TG 226: Predatory mite (Hypoaspis (Geolaelaps) aculeifer) Reproduction test in soil Hypoaspis (Geolaelaps) aculeifer is considered to be a relevant representative of soil fauna and predatory mites in particular.

Mar 20, 2012 OECD, using earthworms and only focusing on short-term (acute) mite Hypoaspis (Geolaelaps) aculeifer (OECD 2008), and larvae of the

This Test Guideline describes a method to assess the effects of chemical substances in soil on the reproductive output of the soil mite species Hypoaspis (Geolaelaps) aculeifer Canestrini (Acari: Laelapidae). It can be used for water soluble or insoluble substances, but not with volatile substances. 2012-08-01 · Mean control mortality (per cent) of Hypoaspis aculeifer after exposure to dimethoate (filled symbols) and boric acid (open symbols) in OECD artificial soil according to the ring test protocol. Test duration was 16 days, except for test no. 10 (14 days).

Ges. Allg. Angew. Ent. 1989, 7 pp. 103?107 [18] A. Ruf 1993). 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.

Test No. 226: Predatory mite (Hypoaspis (Geolaelaps) aculeifer) reproduction test in soil OECD This Test Guideline describes a method to assess the effects of chemical substances in soil on the reproductive output of the soil mite species Hypoaspis (Geolaelaps) aculeifer Canestrini (Acari: Laelapidae).

The standard species are the Collembola, Folsomia candida and the predatory mite, Hypoaspis aculeifer. OECD no. 226 Mar 17, 2021 2003; OECD 2016a) using the predatory mite Gaeolaelaps (Hypoaspis) aculeifer (Laelapidae) to make them appropriate to the assessment of Aquatic Ecotoxicology, Fish Acute Toxicity Test, OECD 203 Terrestrial Ecotoxicology, Hypoaspis aculeifer Reproduction Study in Soil, OECD 226.

Predatory mites are considered important biological indicators to assess potential effects of plant protection products. Toxicity testing of terrestrial mite species is required for authorisation of plant protection products in the European Union in cases where testing of leaf dwelling mites is not relevant, i.e. for defoliating herbicides, or when persistence of the chemical in soil is a concern.

Two microarthropod species, the springtail Folsomia candida and the predatory mite Hypoaspis aculeifer, were exposed in these 4 soils spiked individually with the 3 insecticides. Results show that the collembolan F. candida was more sensitive than the mite H. aculeifer for all 3 insecticides.

soil mite Hypoaspis (Geolaelaps) aculeifer. The mites are exposed under controlled conditions to the chemical which has been mixed into the test substrate (usually OECD artificial soil). H. aculeifer is considered to be a relevant representative of soil fauna and predatory mites in particular for the following reasons:

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).
