A review of recent patents on macroorganisms as biological control agents.

The indiscriminate use of synthetic pesticides has brought undesired problems to human health, agriculture, and the environment. Integrated Pest Management (IPM) and Biological Control (BC) programs, which are based on minimum use of pesticides, are seen as alternative, more ecological solutions to the unintended problems associated with pesticide use. These programs combine the introduction, augmentation, and/or conservation of pest natural enemies, with other protection tools.
