Protocols for laboratory, extended laboratory and semi-field bioassays in risk assessment for non target arthropds - PN0928

Description
The main objective is to refine testing protocols for first and second tier tests required by the proposed EPPO/CoE risk assessment scheme, and to investigate the transition criteria between these testing levels. The project will appraise the applicability and practicality of multiple dose bioassays, comparing dose-response relationships for non-target species both within and between major taxonomic groups (e.g. parasitoids, predatory mites, carabid beetles). Work in a previous project (PN 0801) clearly demonstrated the value of multiple dose tests during first tier (laboratory) testing, and this has now been recommended to replace single dose tests in the new EPPO/CoE scheme. A further recommendation arising from the work done in PN 0801 was the greater use of extended laboratory and semi-field tests during second tier testing. Appropriate second tier tests will be further developed and evaluated during the project, particularly for foliage-dwelling predators and parasitoids which in the past have received limited attention in comparison with ground dwelling predators such as carabid beetles.By ensuring that risk assessment schemes incorporate the most valid and appropriate testing protocols, enabling accurate interpretation of test data by regulation authorities, the research will aid regulatory decisions concerning pesticide use. This will contibute to the policy aims of protecting and enhancing the rural environment and protecting the public.
