ABSTRACT Phyto-parasitic nematodes are associated with affectations in the development and production of agricultural crops, recognized as one of the limiting factors on yields. The need to update the record of these organisms associated with sugar cane in Guantanamo province was the main objective of this research. For this, soil and root samples taken in two cane production units were processed. The determination of genera and species was conducted at the of  Laboratory Nematology of the Provincial Directorate of Plant Protection, also the population was characterized by determining indices of genus and species richness of Margaleff and dominance index of Berger Parker. 24 species of phyto-parasitic nematodes grouped in 16 genera were identified, and Pratylenchus as the most represented genus with 5 species. These results constitute a contribution to knowledge of the nematodes composition associated with the cultivation of sugarcane in the province

Keywords : population density; Meloidogyne; Pratylenchus.
