Luuk Croijmans: Herbivore prevalence poorly predicts yield in diverse cropping systems

Shortlisted for the 2025 Southwood Prize About the research Overview Our study was part of my PhD thesis. I tried to understand how increasing diversity within cropping systems changes trophic interactions and crop damage, together with my knowledgeable promotors, Erik Poelman and Dirk van Apeldoorn; an analytical behemoth, Daan Mertens; and two diligent MSc thesis students, Yufei Jia and Nelson Ríos Hernández. Sustainable alternatives to pesticide … Continue reading Luuk Croijmans: Herbivore prevalence poorly predicts yield in diverse cropping systems

Strip cropping increases the number of slugs and slug predators, but crop damage does not increase

Strip cropping is a farming method in which different crops are grown in adjacent strips in the same field rather than in a field with a single crop (monoculture). This approach can increase biodiversity and help control insect pests, but it is not well understood how strip cropping influences pest slugs. We compared on 20 farms in the Netherlands slugs and their invertebrate predators in … Continue reading Strip cropping increases the number of slugs and slug predators, but crop damage does not increase

Strokenteelt verhoogt het aantal naaktslakken en predatoren van naaktslakken, maar gewasschade neemt niet toe

Strokenteelt is een landbouwmethode waarbij verschillende gewassen naast elkaar in stroken worden geteeld in plaats van in grote percelen met één enkel gewas (monocultuur). Deze aanpak kan de biodiversiteit vergroten en helpen bij de bestrijding van insectenplagen, maar het effect op schadelijke naaktslakken was tot nu toe onduidelijk. Wij onderzochten 20 Nederlandse bedrijven en vergeleken de dichtheid van naaktslakken en hun ongewervelde predatoren in strokenteeltpercelen … Continue reading Strokenteelt verhoogt het aantal naaktslakken en predatoren van naaktslakken, maar gewasschade neemt niet toe

Janina Heinen: Diversified cropping strengthens herbivore regulation

Shortlisted for the 2024 Southwood Prize Janina Heinen talks us through her and colleagues’ latest study which explores how agricultural practices impact predation pressure across prey taxa. About the research Overview We explored predator-prey dynamics in agroecosystems by examining how carabid predator diet preferences shift throughout the crop growing season, and are influenced by the availability of prey under different agricultural management practices. By combining … Continue reading Janina Heinen: Diversified cropping strengthens herbivore regulation
