ABSTRACT

Agroforestry is an intensive land-management system that combines trees and/or shrubs with crops and/or livestock (Nair, 1993). Many of the benefits of agroforestry are derived from the increased diversity of these systems compared to corresponding monocultures of crops or trees. Despite the fact that little research has been conducted on pest interactions within agroforestry systems, agroforestry has been recommended to reduce pest outbreaks usually associated with monocultures. Although the effects of various agroforestry designs on pest populations can be of a varied nature (microclimatic, nutritional, natural enemies, etc.), regulating factors do not act in isolation from one another.
