Commission Regulation (EU) No 283/2013Show full title

8.3.2. Effects on non-target arthropods other than bees U.K.

Circumstances in which required U.K.

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:

• food storage in enclosed spaces that preclude exposure,

• wound sealing and healing treatments,

• enclosed spaces with rodenticidal baits.

Two 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 (1), ER₅₀ (2) 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).

With 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 national competent authorities. The rationale for the choice of test species used shall be provided.

8.3.2.1. Effects on Aphidius rhopalosiphi U.K.

A test shall provide sufficient information to evaluate the toxicity in terms of LR₅₀ and NOEC of the active substance to Aphidius rhopalosiphi.

Test conditions U.K.

Initial testing shall be performed using glass plates.

8.3.2.2. Effects on Typhlodromus pyri U.K.

A test shall provide sufficient information to evaluate the toxicity in terms of LR₅₀ and NOEC of the active substance to Typhlodromus pyri.

Test conditions U.K.

Initial testing shall be performed using glass plates.

LR₅₀, abbreviation for ‘Lethal Rate, 50 %’, that is to say the application rate required to kill half the members of a tested population after a specified test duration.

(2)

ER₅₀, abbreviation for ‘Effect Rate, 50 %’, that is to say the application rate required to cause an effect on half the members of a tested population after a specified test duration.
