Terrestrial Non-Target Arthropod Studies

Non-target arthropods are invertebrates that play an essential role in ecosystems as pest controllers.

Our scientists have extensive experience in conducting studies with these non-target arthropods under laboratory, glasshouse or semi-field conditions. All studies are carried out in line with current international guidelines and guidance documents, and we can adapt our services to provide bespoke tests that meet your specific data requirements.

Our services

  • Test the impact of products on non-target beneficial invertebrates
  • Choose from Tier 1 and 2 laboratory tests, aged-residue tests or higher tier semi-field and field studies
  • Bespoke tests adapted to meet your data requirements
  • All studies are GLP-compliant and conducted to IOBC/WPRS and OECD guidelines

Ecotoxicology services: terrestrial non-target arthropod studies

You can choose from a range of laboratory, extended laboratory and aged-residue studies, all conducted to IOBC/WPRS and OECD guidelines:

Laboratory tests

Fera offers standard Tier 1 laboratory tests with the parasitoid wasp Aphidius rhopalosiphi and the predatory mite Typhlodromus pyri.

The organisms to be tested are exposed to treated glass surfaces, to assess the risk to each selected species, resulting in detailed insights into the impacts of your compounds.

Extended laboratory tests

If required, Tier 1 tests can be followed up by extended Tier 2 laboratory tests, in which the test species are exposed to a treated natural substrate (i.e leaf disks or natural soil or whole plant) under laboratory conditions.

All of these studies can be carried out on the following non-target arthropod species:

  • Typhlodromus pyri (Predatory mite)
  • Aphidius rhopalosiphi (Parasitic wasp)
  • Chrysoperla carnea (Green lacewing)
  • Coccinella septempunctata (Ladybird)
  • Aleochara bilineata (Rove beetle)
  • Pardosa spp. (Wolf spider)
  • Poecilus cupreus (Carabid beetle)
  • Orius laevigatus (Predatory bug)

Aged-residue tests

To test the degradability of your plant-protection products outdoors, we can carry out aged-residue tests. Whole plants are sprayed with your product, to mimic a field application. We then test the residual toxicity at set intervals to assess the time of ageing needed for the residues to cause effects below an acceptable threshold within the environment. Pesticide spray residues can be aged under laboratory or (semi-)field conditions.
