SALTO Adriana SALVO Biología Crops Spontaneous vegetation Conservative Biological Control Parasitoids (Hymenoptera: Aphidiinae; Aphelinidae) exert a significant pressure regulation in pest aphid populations (Hemiptera: Aphididae). In order to contribute to the biological control of aphids, the objective of this study was to identify plant-aphid-parasitoid trophic interactions occurring in crop fields and their vegetated borders and to provide an identification key for parasitoids recorded in the province of Santa Fe (Aphidiidae and Aphelinidae). Over four years, (2009-2013), 10 transects of 0.5 m in crops (alfalfa, oats, wheat and canola) and non-crop edges were randomly selected in 28 fields from six districts of the province. Samples of each observed species were taken and mummies (parasitized aphids) were reared in the laboratory, until adult emergence, for identification. Regional matrix for plantaphid-parasitoid interaction registered in crops and non-crop and useful aspects for aphid pest control are discussed. Known host ranges for eleven species of parasitoids were expanded and an illustrated key based on female morphology of both groups of parasitoids, and another based on mummies morphology and other evidences of parasitoids emergence from their hosts, were provided. 2015 artículo científico 1851-7471 https://www.redalyc.org/articulo.oa?id=322043152005 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.74 |
