摘要: Abstract Considerable numbers of arthropods were intercepted by Malaise traps at the interface abandoned, organic and sprayed apple orchards with adjacent woodlands. Low exchange was registered between abandoned orchard its margins. The data suggest that invaded from surrounding woodlands subsequent colonization trees influenced management intensity, vegetational diversity distance borders. More natural enemies established remained in than orchard, whereas more rosy aphids several species leafhoppers orchard. A declining gradient predator abundance on observed to orchards, paralleling a decrease an increase intensity. Predators abundant close centers managed orchards. Herbivores exhibited opposite trend. rates which predators removed prey placed cards ground higher field margins Predation highest cover crop.
