MARTINEZ GALLARDO, José Ángel et al. Phytoparasitic nematodes associated with the cultivation of papaya (Carica papaya L.) in Colima, Mexico. Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.2, pp.317-323. ISSN 2007-0934.

This study aimed to detect and identify phytoparasitic nematodes associated with the cultivation of papaya (Caricapapaya L.) in the municipalities of Tecomán and Colima, Colima. We selected ten orchards, seven ranches in which samples were collected roots and rhizosphere soil, in each sample was quantified and identified populations of phytoparasitic nematodes. For specific identification of Meloidogyne, perineal cuts were analyzed and confirmed females by chain reaction (PCR). The genera of phytoparasitic nematodes were detected and identified: Aphelenchus, Ditylenchus, Helicotylenchus, Paratylenchus, Pratylenchus, Rotylenchulus, Rotylenchus, Trophurus, Tylenchorrhynchus, Tylenchus, and Meloidogyne, with the species M. incognita. The results allow the first report of M incognita associated with papaya in Colima, Mexico.

Keywords : Meloidogyne; Rotylenchulus; chain reaction (PCR); rhizosphere soil.
