On the identity of Xiphinema americanum in Chile with a key to the Xiphinema species occurring in Chile

Abstract

In 1971 Allen et al. reported Xiphinema americanum sensu lata in association with different fruit crops and grape from various localities in Chile. From an examination of Allen's slides which are in the nematode collection of the Departamento de Sanidad Vegetal de la Facultad de Ciencias Agrarias y Forestales de la Universidad de Chile it was concluded that X. americanum sensu stricto does not occur in Chile. The specimens studied were identified as X. californicum, X. floridae, x. inaequale, X. pachtaicum, x. peruvianum and X. utahense. The morphometric characters of the species of Xiphinema, so far found in Chile, are provided together with a key for their identification.
