Foreign exploration for predators: a proposed new methodology.

That most biological control success stories involve parasitic rather than predatory natural enemies is a well-entrenched myth. In fact, recent analyses have shown that introduced parasitoids and predators have not differed significantly in their rates of establishment or success as agents of biological control. However, it is true that introductions of predators have been attempted much less often than introductions of parasitoids. This may be partly because of controversy over the attributes of the ideal natural enemy. A more basic obstacle has been the lack of a methodology for identifying any but the most prey-specific of predators of target pests. I propose a new methodology, using on-the-spot serological stomach analysis of predators. The feasibility of this approach is illustrated with data from monoclonal antibody-based ELISA assays of predators fed larvae of species of the corn earworm complex.
