Interpretive Summary: The biology of a South American sharpshooter was studied to help in the control of glassy winged sharpshooter. Since the early 1990's, the GWSS has become a major pest in California and America. We inform about the host plants , distribution and egg parasitoids of this South American sharpshooter. One of the egg parasitoids of this sharpshooter is already in the United States quarantine and permits for release in California are under appraisal.

Technical Abstract: Bionomics of the proconiine sharpshooter Oncometopia tucumana Schroder (Hemiptera:Cicadellidae) from northern Argentina is reported. Leafhoppers were monitored during the entire season in a citrus orchard in Horco Molle, Tucuman Province, and also sampled in Jujuy and Salta provinces. The sharpshooters were found from spring to late fall; as adults and females do not lay eggs from Apr to Oct. Ocnometopia tucumana is polyphagous, 12 plants in 11 families wer recorded as its hosts for the first time. Egg masses of O. tucumana were attacked by 3 parasitoid species, Gonatocerus annulicornis (Ogloblin), G. metanotalis (Ogloblin)and G. tuberculefemur (Ogloblin) (Hymenoptera: mymaridae), that collectively produced egg mortality close to 605. Gonatocerus annulicornis was the main egg parasitoid, emerging from nearly 80% of the parasitized eggs.
