  "text": "Effects on non-target terrestrial arthropods shall be investigated for all active substances except where plant protection products containing the active substance are for exclusive use in situations where non-target arthropods are not exposed such as:\nfood storage in enclosed spaces that preclude exposure,\nwound sealing and healing treatments,\nenclosed spaces with rodenticidal baits.\nTwo indicator species, the cereal aphid parasitoid Aphidius rhopalosiphi (Hymenoptera: Braconidae) and the predatory mite Typhlodromus pyri (Acari: Phytoseiidae) shall always be tested. Initial testing shall be performed using glass plates and mortality (and reproduction effects if assessed) shall be reported. Testing shall determine a rate-response relationship and LR50, ER50 and NOEC endpoints shall be reported for assessment of the risk to these species in accordance with the relevant risk quotient analysis. If adverse effects can be clearly predicted from these studies then testing using higher tier studies may be required (see point 10.3 of Part A of the Annex to the Regulation (EU) No 284/2013 for further details).\nWith active substances suspected of having a special mode of action (such as insect growth regulators, insect feeding inhibitors) additional tests involving sensitive life stages, special routes of uptake or other modifications, may be required by the ... competent authorities. The rationale for the choice of test species used shall be provided.",
