Insects are man’s primary competitor. In an effort to compete successfully with insects for food and fiber, man has employed numerous techniques for the suppression of pest insect populations. Biological control is one approach that has been used with some success against many insect pests. Augmentation is the phase of biological control concerned with the manipulation of natural enemies to make them more efficient in applied biological control programs. DeBach (1964) observed that the possibilities of augmentation have not been explored thoroughly. The field of biosystematics is similarly poorly explored but shows great promise as a research tool for biological control workers. In many instances biosystematics may be the only course available to biological control workers.
