Plants are not capable of running away from their enemies, ., the herbivores that may eat them. However, under certain circumstances, plants can rely on the natural enemies of insect herbivores for protection. These natural enemies include other insects that are predators and parasitoids. Habitat manipulation, which is also referred to as “Ecological Engineering”, focuses on reducing mortality of natural enemies, providing the supplementary resources and manipulating host plant attributes for the benefit of natural bio-agents. This can be achieved by enhancing the plant diversity and by providing adequate refugia in the agro-ecosystem. In this article we review the use of natural enemies in crop pest management and describe m research needed to better meet information needs for practical applications. |
