A. Y.  aUnveiling the structure and distribution of plant-parasitic nematode communities in soybean fields in southern of the Brazil.h[electronic resource]  c2021  aOur study aimed to assess the structure and distribution of plant-parasitic nematodes in soybean [Glycine max (L.) Merr] in the south of Brazil. High taxonomical diversity was found, with records of 10 genera of plant-parasitic nematodes (PPNs), including important pests, such as Meloidogyne (mostly M. javanica with small esterase variability), Pratylenchus (mostly P. brachyurus) and Helicotylenchus spp. The Shannon-Weaver index (H′) ranged from 0 to 1.23 (mean = 0.37), whereas Pielou?s evenness (J) ranged from 0 to 1 (mean = 0.51). The amount of PPNs (0 to 22,050 per 250 cm3 soil, and 0 to 15,500 per 10 g roots), incidence and abundance for Meloidogyne (28.6%; 50 to 19,250 per 250 cm3), Pratylenchus (45.1%; 50 to 550 per 250 cm3), Helicotylenchus (91.2%; 50 to 9,150 per 250 cm3), Tylenchus (34.1%; 50 to 550 per 250 cm3), Xiphinema (33%; 50 to 250 per 250 cm3), Mesocriconema (15.4%; 50 to 2,000 per 250 cm3), Rotylenchus (8.8%; 50 to 1,900 per 250 cm3), Hemicycliophora (1.1%; 50 per 250 cm3), Discocriconemella (1.1%; 950 per 250 cm3) and Tylenchorhynchus (1.1%; 50 per 250 cm3) were related differently to the bioclimatic variables under analysis. Our findings provide an update for the status of PPNs in the south of Brazil and suggest important epidemiological issues linked to the management of these pests in the near future.  aDoença de Planta  aGlycine Max  aNematóide  aSoja1 aGOMES, C.
