Vegetational designs for insect-habitat management

Abstract

/ Insect habitats =n anthropocentnc ecosystems consist of crop plants or forest trees and the coexisting non-crop vegetation. The manipulation of the spatial and temporal arrangement of these plant communities can trigger direct or indirect effects on insect pest populations and their assoc=ated natural enemy complexes. In this article habitat management is viewed as a techn=que to design plant associations that support populations of natural enemaes or that exert deterrent effects on herbivorous =nsects.

“…and Stewart 1990), but it may also contribute to keeping insect pest populations below economic thresholds within agricultural landscapes (Altieri 1983, Macdonald and Smith 1990, Welch 1990, Banks 2000, Ekbom 2000 by increasing the effectiveness of natural enemies (Wratten andThomas 1990, Williams andMartinson 2000). However, wild hosts in uncultivated habitats may also harbor insect pests and diseases (Barrett 2000, Jeanneret 2000.…”
