Effect of Habitat Heterogeneity on the Diversity and Density of Pollinating Insects,g natural bee resources in various ecosystems and rules governing the distribution of Apoidea. The studies have been carried out in natural and agricultural landscapes, mainly in the area of Poland and Rumania. The diversity and density of Apoidea have been investigated also in other parts of Europe

Diversity and Movement Patterns of Leaf Beetles (Coleoptera: Chrysomelidae) and Leafhoppers (Homopt (Meyer & Turner II, 1994). Much of the land resulting from this activity is cleared and converted to unimproved pasture, forming a patchy landscape mosaic of forest and glade (Franklin & Forman, 1987) in a number of life zones throughout the region.

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
