Natural enemy for Asian fruit fly is two species

摘要

CABI scientists have led new research which reveals that a natural enemy for the prolific Asian fruit fly Drosphila suzukii - previously believed to be one species - is in fact two with only one of the parasitoids proving effective against the pest.The scientists from CABI's Swiss Centre Delemont, as well as colleagues from INRAE in France, used a combination of molecular analysis and crossing experiments to gather evidence that Ganaspis brasiliensis is a complex of at least two cryptic species.
