Biological and conventional control can yield similar economic returns to pest control expenditures. Finding is based on economic feasibility study of using the parasitic wasp, Pediobius foveolatus, in place of conventional insecticides to control Mexican bean beetle on soybeans. Insect scouting in conjunction with use of the parasite is also compared with conventional control. Widespread use of the parasite to control the beetle could reduce use of insecticides without compromising soybean producers' revenues.
