Management of genetics of biological-control introductions

Reviews data relevant to three topics that are central to biological-control introductions and to identify areas where some progress has been or can be made: 1) what genetic barriers prevent using a natural enemy from one prey/host species against another closely related prey/host species? If barriers exist, how can they be overcome? 2) Does laboratory rearing for biological-control introductions cause maladaptation of field conditions? If so, how can such maladaptation be avoided? 3) Is adaptation after introduction important for establishment and/or control? If so, how can such adaptation be promoted? -from Authors
