Females of the polyphagous ichneumonid Exeristes roborator (F.) characteristically learn to respond to artificial host microhabitats in which they are fed either natural or factitious host larvae. In a laboratory experiment, they learned to associate a host with a glass pipette feeding device. However, they became reproductively mature without learning to respond to the feeding device when fed only hemolymph of coddled larvae of Galleria mellonella (L.). Thus, the adverse effects of learning by parasitoid females intended for inundative releases can be avoided by the appropriate prerelease feeding regime.
