Agricultural intensification has resulted in simplification and fragmentation of natural landscape. Such expansion has been characterized by larger agricultural fields and the removal of natural habitats. These changes have had as consequences a rapid decline in biodiversity with most remaining species mostly located in ecotones and natural undisturbed habitats. This mosaic landscape also influences the ecosystem functions such as the presence and migration of natural enemies that can control pest in agricultural fields. Due to their stability and heterogeneity, natural habitats can provide shelters and alternative food for these species thus maintaining their critical roles in agroecosystems. Considering the need for such diversity in these ecosystems, sustainable pest management requires a landscape management approach.. Sustainable pest management can only be achieved if conservation of biodiversity takes into account the mosaic pattern of this landscape, thus reducing distances between habitats for poorly-dispersed and specialized natural enemies. Structurally complex landscapes with high habitat connectivity may enhance the roles of beneficial species by efficiently regulating pest populations. Their heterogeneity allows for greater level of species diversity where natural habitats compensate the homogeneity and reduction in diversity in agricultural fields. Complex landscapes characterized by highly connected crop and non-crop mosaics may be best for the survival of natural enemies and long-term conservation of biodiversity. However, further studies are required to better design agricultural landscapes that optimally maintain biodiversity of natural enemies in support of regional ecologically pest management.
