Semi-natural habitats in arable land could play an important role as a source of arthropod predators. The presence of these arthropods can lead to a significant suppression of pests. Field data concerning the presence of landscape elements and cereal aphids are analysed. The results suggest that field shape and higher abundance of semi-natural habitat lead to a reduction of pest populations in adjacent crops. Furthermore, a first step towards a model (Bio-Support) predicting the colonisation of arable fields by polyphagous predators is made. Further development of such tools should be promoted in order to make them useful as decision support systems for farmers.
