Integrating crop and landscape management into new crop protection strategies to enhance biological control of oilseed rape insect pests

摘要: The development of sustainable cropping systems is a major challenge for agronomists and crop scientists in many regions the world. prophylactic uses broad spectrum insecticides are actually main solution farmers to control insect pests. Therefore, there growing need develop innovative protection strategies through an integrated approach which aims at favouring natural enemies enhancing biological agroecosystems. such requires thorough understanding agroecosystem functioning. In this chapter, we present effects different elements, from field scale landscape that known enhance agroecosystems limit pest damage with particular reference oilseed rape. Linking management ecology brings regional perspective populations. Available techniques often added together rather than combined way rarely evaluated environmental economical criteria. methodological framework design assess systems, emphasis on complementariness between models, systemic trials more analytical approaches. Implementation implies new thereby increased participation stakeholders policy makers.
