The root-lesion nematodes Pratylenchus spp. have a wide geographic distribution and a large number of host plants. These migratory endoparasites are found associated with sugarcane around the world causing diseases that induce permanent losses in productivity. Although this genus has ordinarily been reported in low-producing sugarcane areas in northeastern Brazil, studies of the species occurrence are few and restricted to a very low number of sites and samples. This study aimed to morphologically and morphometrically characterize Pratylenchus species from different sugarcane regions of Pernambuco state, where composite samples of soil and roots were collected on 30 farms from three sugarcane mills. The external morphological characters of the nematode body from different populations had a diagnostic value compatible with those obtained in the literature, showing the dominance of P. zeae (87%) in the region. Atypical populations of the genus Pratylenchus were also found.
