Many agroecosystems are unfavorable environments for natural enemies due to high levels
of disturbance. Habitat management, a form of conservation biological control, is
an ecologically based approach aimed at favoring natural enemies and enhancing biological
control in agricultural systems. The goal of habitat management is to create a suitable
ecological infrastructure within the agricultural landscape to provide resources such
as food for adult natural enemies, alternative prey or hosts, and shelter from adverse
conditions. These resources must be integrated into the landscape in a way that is
spatially and temporally favorable to natural enemies and practical for producers
to implement. The rapidly expanding literature on habitat management is reviewed with
attention to practices for favoring predators and parasitoids, implementation of habitat
management, and the contributions of modeling and ecological theory to this developing
area of conservation biological control. The potential to integrate the goals of habitat
management for natural enemies and nature conservation is discussed.
