Abstract
A fundamental difficulty in classical biological control is to ensure that natural enemy releases have appropriate genetic quality, which, if lacking, may reduce the species’ adaptability to the new environment resulting in lowered impact or even failure. “Biotypes” of Laricobius nigrinus (Coleoptera: Derodontidae), a predator of Adelges tsugae (Hemiptera: Adelgidae), may provide an example of this phenomenon.
