Abstract

The biology of <i>Tetrastichus galactopus</i>, a hyperparasite of <i>Apanteles rubecula</i> and <i>A. glomeratus</i> in North America, is reviewed. The female hyperparasite attacks its hosts while they are larvae in their primary host, <i>Pieris rapae</i>. although free-living cocoons of <i>A. glomeratus</i> may also be attacked. In Vancouver, where <i>A. rubecula</i> is the only available host, <i>T. galactopus</i> is active from July through September and probably overwinters as a pupa or adult within the host cocoon. The significance of hyperparasitism to the success of biological control efforts using <i>Apanteles</i> is discussed.
