Molecular and Morphological Characterization of needle nematode Longidorus donghuicus sp. n. and Dagger nematodes Xiphinema brevicolle Lordello et Costa, 1961(Dorylaimida, Longigoridae) from Northeast China
The studies explore the ecological distribution of Longidorus and Xiphinema species in various habitats, including forests, pear, peach, apple, walnut and blue barriers orchards. The study underscores the importance of integrating morphological, morphometric, and molecular approaches for accurate species identification, phylogenetic analysis, and understanding the ecological roles of these nematodes in agricultural and natural ecosystems.
