摘要: Two experiments were done to determine the susceptibility of six wild potato accessions aphids Macrosiphum euphorbiae (Thomas) (Hemiptera: Aphididae) and Myzus persicae (Sulzer). Densities aphid colonies compared between caged Solanum pinnatisectum Dunal (Solanales: Solanaceae), S. polyadenium Greenmam, tarijense Hawkes, infundibuliforme Philippi, oplocense stoloniferum Schlechted Bouche, commercially cultivated plant tuberosum L. cv. Desiree. Moreover Colorado beetle Leptinotarsa decemlineata (Say) (Coleoptera: Chrlysomelidae), flea Epitrix cucumeris (Harris), leafhopper Empoasca fabae (Harris) Cicadellidae) was that Desiree in field. Results indicated more resistant M. than 2004, but not 2005. Moreover, decemlineata, E. fabae.
