[Survey of egg parasitoids of Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae) in the western litoral of Uruguay].  c2010  aArticle history: Recibido 9/9/09 // Aceptado 2/8/10.  aRESUMEN. Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae) es la chinche predominante en los sistemas de rotaciones cultivos-pasturas del Uruguay. Esta especie provoca pérdidas en soja y leguminosas forrajeras y existen escasos registros de controladores naturales. Entre 2004/05 y 2006/07 se realizaron muestreos de huevos en Soriano, Paysandú y Colonia para determinar la incidencia de parasitoides en P.guildinii, en cultivos de soja y leguminosas forrajeras representativos de la región tradicional de producción del litoral oeste. Los parasitoides encontrados fueron: Telenomus podisi (Ashmead), Trissolcus brochymenae (Ashmead), Trissolcus basalis (Wollaston), Trissolcus urichi (Crawford) y Trissolcus teretis (Johnson). Telenomus podisi predominó, alcanzando, en promedio, el 93,25% de los parasitoides emergidos de los huevos colectados.  SUMMARY. Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae) is the main stink bug in the agricultural-grazing production systems of Uruguay. This species causes losses in soybeans and grazing legumes and accounts a few reports of natural enemies. In order to assess the incidence of egg parasitoids for this pentatomid in soybeans and forage legumes in Western Uruguay, egg samplings were made between 2004/05 and 2006/07 at Soriano, Paysandú and Colonia. Telenomus podisi (Ashmead), Trissolcus brochymenae (Ashmead), Trissolcus basalis (Wollaston), Trissolcus urichi (Crawford) and Trissolcus teretis (Johnson) were the scelionid species of egg parasitoids for P. guildinii in those regions of Uruguay. T. podisi predominated achieving, in average, 93.25% of the adult parasitoids emerged from the total sampled eggs.  aLEGUMINOSAS FORRAJERAS  aPARASITISMO  aSCELIONIDAE  aSOJA  aTELENOMUS PODISI  aALFALFA  aCHINCHES  aFORAGE LEGUMES  aGLYCINE MAX  aLOTUS CORNICULATUS  aMEDICAGO SATIVA  aPARASITISM  aPARASITOIDES  aPIEZODORUS GUILDINII  aSCELIONIDAE  aSOYBEAN  aTELENOMUS PODISI  aTRÉBOL BLANCO  aTRÉBOL ROJO  aTRIFOLIUM PRATENSE  aTRIFOLIUM REPENS  aTRISSOLCUS BASALIS  aTRISSOLCUS BROCHYMENAE  aTRISSOLCUS TERETIS  aTRISSOLCUS URICHI1 aRIBEIRO, A.1 aALZUGARAY, R.1 aSILVA, H.1 aÁVILA, I.1 aLOIÁCONO, M.  tAgrociencia Uruguay, 2010gv. 14, no. 2, p. 22-25
