The options available under Entry Level Stewardship, Organic Entry Level Stewardship <strong>and</strong> Higher LevelStewardship schemes were appraised to identify the types <strong>of</strong> <strong>natural</strong> <strong>enemies</strong> that they can support <strong>and</strong> for<strong>their</strong> potential to improve biocontrol.Studies <strong>of</strong> the invertebrate <strong>natural</strong> <strong>enemies</strong> <strong>of</strong> cereal <strong>and</strong> oilseed rape <strong>pests</strong> are extensive but usuallyconducted as isolated studies <strong>of</strong> individual species or guilds. A comprehensive list <strong>of</strong> the known invertebrate<strong>natural</strong> <strong>enemies</strong> was compiled.Aims• To identify important gaps in knowledge regarding the biology <strong>and</strong> ecology <strong>of</strong> economicallyimportant <strong>pests</strong> <strong>and</strong> <strong>their</strong> invertebrate <strong>natural</strong> <strong>enemies</strong> in arable crops.• To review the impacts <strong>of</strong> changes in farming practice, for example agri-environment schemes,tillage, rotations on the dynamics between <strong>pests</strong> <strong>and</strong> <strong>their</strong> <strong>natural</strong> <strong>enemies</strong>.Objectives• Define a list <strong>of</strong> target species <strong>of</strong> <strong>pests</strong> <strong>and</strong> <strong>their</strong> invertebrate <strong>natural</strong> <strong>enemies</strong>.• Review published literature <strong>and</strong> recent/ongoing projects in the UK <strong>and</strong> overseas on the biology <strong>and</strong>ecology <strong>of</strong> existing <strong>and</strong> emerging <strong>pests</strong>.• Identify changes in the prevalence <strong>of</strong> different <strong>pests</strong>.• Review relevant changes in crop production, for example Environmental Stewardship schemes,tillage <strong>and</strong> rotations.• Assemble a list <strong>of</strong> researchers working in this area.7
