The elements of biodiversity, both floristic and faunistic, that sustain efficacious levels of beneficial insects in farmland settings are challenging to obtain, since farming constitutes a disturbance of the land, and therefore a disturbance of natural systems and a diminishing of the biotic elements. The greater the disturbance, the fewer the opportunities for the natural biota to exist. Present trends in biodiversity development center on equalizing ecological losses through crop diversification, adjacent landscape preservation, and intentional introduction of biotic agents (Michal, 1994). Landscape ecology and biodiversity are ecologically connected and mutually dependent (Carroll, 1990; van Hook, 1994). Overall activities that support and increase diversity and ecological stability in agroecosystems include, but are not limited to, development of biocorridors and biocenters, heterogeneous crops and crop structuring, polycultural crop rotation, biocontrol introductions, and pesticide use modifications (Paoletti et al., 1992; Petr and Dlouhy, 1992).
