2021-03-17 In order to assess the influence of temperature on pesticide toxicity to soil fauna, specimens of the predatory mite Hypoaspis aculeifer and the springtail Folsomia candida were exposed in artificial soil spiked with different concentrations of three pesticides (dimethoate, chlorpyrifos and deltamethrin) at 20°C vs 28°C for the mites and 20°C vs 26°C for the springtails. Essai n° 226 : Essai de reproduction d'un acarien prédateur (Hypoaspis (Geolaelaps) aculeifer) dans le sol Lignes directrices de l'OCDE pour les essais de produits chimiques, Section 2 … 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. Adult females of similar age are exposed to a range of concentrations of the test substance Essai n° 226 : Essai de reproduction d'un acarien prédateur (Hypoaspis (Geolaelaps) aculeifer) dans le sol Cette Ligne directrice décrit une méthode pour évaluer les effets de substances chimiques dans le sol sur la reproduction de l’espèce d’acariens Hypoaspis (Geolaelaps) aculeifer Canestrini (Acari: Laelapidae). Based on long-term experience, we offer studies on toxicity to predatory mites (Hypoaspis aculeifer, acc.

Hypoaspis (Geolaelaps) aculeifer is considered to be a relevant representative of soil fauna and predatory mites in particular. It is worldwide distributed and can easily be collected and reared in the laboratory. Synchronized adult females of Hypoaspis aculeifer, of 28-35 days after the start of egg 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.

Predatory mite (Hypoaspis (Geolaelaps) aculeifer) reproduction test in soil.

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 t …

Candolfi, In addition, 2 common test soils, OECD artificial soil and European (Landwirtschaftliche Untersichungs‐ und Forschungsanstalt [LUFA]) 2.3 soil, were used in OECD standard reproduction tests. 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. 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.

It can be used for water soluble or insoluble 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: OECD GUIDELINES FOR TESTING CHEMICALS Predatory mite reproduction test in soil (Hypoaspis (Geolaelaps) aculeifer) INTRODUCTION 1. This Test Guideline is designed to be used for assessing the effects of chemical substances in soil on the reproductive output of the soil mite species Hypoaspis (Geolaelaps) aculeifer Canestrini (Acari: Laelapidae) (1,2).
