Parasitoid Community Structure,ntaining small patches of cropland nested within extensive and interconnected areas of non-crop vegetation. This diversity in the structure of agricultural landscapes can have strong impacts on the diversity, abundance and effectiveness of insect natural enemies that occur within crops (Szentkriraly

The Impact of Field Boundary Habitats on the Diversity and Abundance of Natural Enemies in Cereals, 1988). The linear structures are typically grass boundaries or hedges between fields, along farm tracks, roadsides, drainage ditches, water courses and forest edges (Greaves and Marshall, 1987). These semi-natural, remnant biotopes have been included in recent ecological studies of agricultural eco
