New data on three plant-parasitic nematode species of the genus Longidorus (Nematoda: Longidoridae) from Poland

Abstract

More than 4,100 plant-parasitic nematodes species have been described to date, some of which are of significant economic importance since they cause losses in agriculture. This paper presents new data on three species of the genus Longidorus: L. attenuatus, L. elongatus and L. euonymus from Poland. The study was based on 1,138 soil samples taken from different regions of the country. A total of 77 populations of L. elongatus, 23 of L. attenuatus and 7 of L. euonymus were found which corresponds with 6.76%, 2.02% and 0.62% of all analyzed samples, respectively. Distribution maps are presented together with data on the morphometrics, molecular markers D2-D3 28S rDNA and data on host plants on which the nematodes were found.
