Genetic variability of Diadegma sp., parasitoid of diamondback moth using RAPD-PCR

Rose Monnerat Soraya Leal-Bertioli David Bertioli Tariq Butt Dominique Bordat About the authors

The genus Diadegma has species that are parasitoids of larvae of diamondback moth, Plutella xylostella, one of the most important pests of Brassicacea. This genus has a worldwide distribution. Representative samples of three Diadegma populations from Brazil, Reunion Island and Malaysia were characterized by RAPD-PCR. No intra-population variability was found. However, the high coefficient of genetic similarity between the populations suggests that they could belong to different species.
