Effects of sown weed strips in cereal fields on the abundance of spiders (Arachnida: Araneae) and cereal aphids (Homoptera: Aphididae)



Effects of sown weed strips in cereal fields on the abundance of spiders (Arachnida: Araneae) and cereal aphids (Homoptera: Aphididae)



Bulletin OILB/SROP 21(8): 29-37



Creating non-crop habitats within fields could be a management tool to augment densities of natural enemies of important crop pests. For a period of three years the effects of sown weed strips on the abundance of spiders and cereal aphids were investigated in two fields of winter wheat near Hannover, Northern Germany. Spiders were caught by D-vac-sampling, aphid densities were assessed by tiller counts. In the weed strips a dense vegetation with high structural complexity developed.
