Temelucha interruptor
Temelucha interruptor is a parasitoid wasp in the family Ichneumonidae that attacks larvae of the pine shoot moth (Rhyacionia buoliana). The species has been introduced to North America for biological control but exhibits problematic behavior by preferentially attacking host larvae already parasitized by the braconid wasp Orgilus obscurator. This interference reduces the effectiveness of biological control programs targeting R. buoliana. The species is native to Europe, with established populations in Denmark and Sweden, and has been recorded in the conterminous United States.
