Abstract

DESGARENNES, Damaris; SANCHEZ-NAVA, Petra; PENA-SANTIAGO, Reyes  and  CARRION, Gloria. Nematode fauna associated with the rhizosphere of potato crop (Solanum tuberosum) grown in the region of Cofre de Perote, Veracruz, Mexico. Rev. Mex. Biodiv. [online]. 2009, vol.80, n.3, pp.611-614. ISSN 2007-8706.

Nematode species associated with the rhizosphere of Solanum tuberosum were identified and classified into trophic groups from soils highly infected by the golden potato cyst nematode (Globodera rostochiensis) in a single crop cycle in the producing zone on the Cofre de Perote, Veracruz, Mexico. Seven genera (Aphelenchoides, Aphelenchus, Crassolabium, Mesodorylaimus, Plectus and Steinernema) and 8 species (Aporcelaimellus obtusicaudatus, Ecumenicus monohystera, Acrobeles mariannae, Acrobeles singulus, Acrobeloides nanus, Cruznema tripartitum, Eucephalobus oxyuroides, and Globodera rostochiensis) were found in association with the rhizosphere of cultivated potatoes. Crassolabium sp. and E. monohystera are recorded for the first time in México.

Keywords : nematodes; potato crop; trophic group.
