VIRLA, Eduardo G  y  OLMI, Massimo. Dryinidae (Hymenoptera: Chrysidoidea) parasitoids of the corn leafhopper, Dalbulus maidis (Delong & Wolcott) (Hemiptera: Cicadellidae), in Argentina, with description of the male of Gonatopus moyaraygozai Olmi. INCI [online]. 2007, vol.32, n.12, pp.847-849. ISSN 0378-1844.

The parasitoids of the Corn Leafhopper, Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Auchenorrhyncha) were studied in Tucumán Province, Argentina. Leafhoppers parasitized by Dryinidae (Hymenoptera: Chrysidoidea) were collected in cornfields from Dec 2003 to Apr 2005. Dryinid adults belonging to three species, Gonatopus caraibicus (Olmi), Gonatopus contortus Olmi, and G. moyaraygozai Olmi, were obtained. G. moyaraygozai is quoted for the first time in Argentina, and the male is described for the first time. This contribution presents the first field host-association record for G. caraibicus and D. maidis; in addition, G. contortus, and G. moyaraygozai are cited for the first time attacking Corn Leafhopper populations. Data on the parasitization rate by G. moyaraygozai are given.
