Summary 1. Parametric intensity and spatial arrangement analyses were used to investigate the spatial pattern of the slugs Arion intermedius and Deroceras reticulatum. 2. The spatial lag of sampling (distance between sampling points) was shown to be

Molecular ecology techniques are increasingly used to study invertebrate foodwebs and trophic interactions in the field. However, the study of subterranean foodwebs is currently constrained by the difficult, laborious and often expensive methods that

DNA-based techniques are providing valuable new approaches to tracking predator–prey interactions. The gut contents of invertebrate predators can be analysed using species-specific primers to amplify prey DNA to confirm trophic links. The problem i

Summary In a replicated field experiment, ryegrass, vetch and red clover were grown or the soil was kept bare over a 2–month period in summer to compare the effects of these treatments on slug damage to the following crop (Chinese cabbage) and on t

A simple mathematical model was developed, using ordinary differential equations, to understand the dynamics of Deroceras reticulatum populations. Field data from a long term experiment were interpolated to give daily data for the numbers of slugs m

Phyllodecta (=Phratora) vulgatissima and P. vitellinae (Coleoptera: Chrysomelidae) are important pests of willows and poplars. Their differences in host species preference may provide a non-chemical control strategy for pest control. However, little

The impact of predation by the generalist carabid beetlePterostichus melanarius(Illiger) on populations of the field slugDeroceras reticulatum(Müller), and the effects of prey size on the predator–prey interaction, were measured under semi-field c

Although communities of generalist invertebrate predators are known to be capable of suppressing pests, little is known about the long-term population dynamics of individual species of generalist predators and single classes of prey in the field. We

Earthworms provide a major potential source of alternative food for polyphagous predators, such as carabid beetles, that are natural enemies of slugs, aphids and other agricultural pests. Non-pest prey may foster larger numbers of natural enemies, wh
