- Relevamiento y evaluación de parasitoides de huevo para el control de Cydia pomonella (Lepidoptera: Tortricidae) y Grapholita molesta (Lepidotera: Tortricideae) Oscar E. TORTOSA Agustín CARMONA Juan Carlos MONJE Mónica GIARDINA Pablo MANZANO Eduardo MARTINEZ Biología Field release Egg parasitoids Biological control Trichogramma cacoeciae From October to April 2005-2006 and 2006-2007 we surveyed and identi - fied egg parasitoids of Cydia pomonella (L.) (Lepidoptera: Tortricidae) and Grapholita molesta (Busck) (Lepidoptera: Tortricidae) in three sites of Mendoza, Argentina. Tricho - gramma cacoeciae Marchal (Hymenoptera: Trichogrammatidae) was collected in all surveyed sites both years from both pest species. Trichogramma pretiosum Riley (Hy - menoptera: Trichogrammatidae) was found in only one site in December 2005. In 2008 and 2009 T. cacoeciae was reared, released and its efficacy for the control of C. pomo - nella and G. molesta was assessed through fruit damage. For evaluation, we carried out two field trials in two organic pear orchards. In one orchard the average fruit damage caused by C. pomonella and G. molesta was 5.07% ± 0.82 (non-release control 15.60% ± 4.73) while in the other it was 1.92% ± 0.50 (non-release control 11.34 % ± 1.13). Both trials showed significant statistical differences between treated and untreated orchards. 2014 artículo científico 1851-7471 https://www.redalyc.org/articulo.oa?id=322032818004 es http://www.redalyc.org/revista.oa?id=3220 Revista de la Sociedad Entomológica Argentina application/pdf Sociedad Entomológica Argentina Revista de la Sociedad Entomológica Argentina (Argentina) Num.3-4 Vol.73
