Resumo


Abstract: The objective of this study was to determine the identity, morphological characteristics, molecular phylogenetic, and Pratylenchus populations and population density in areas grown with banana trees. Root collections were carried out at each point in banana orchards in Recife. Subsequently, the extractions and morphological and molecular identification of the nematodes were carried out. Two species were identified: P. coffeae and P. brachyurus, with a predominance of P. brachyurus. The occurrence of these species of nematodes, and the prevalence of P. brachyurus inform new data on parasitism Pratylenchus banana, and occasioning severe damage to the crop.

Keywords: Morphometry, Phylogeny, Nematode.
