PLANT PARASITIC NEMATODES FROM UNIRRIGATED FIELDS IN ALHAMA, SOUTHEASTERN SPAIN
AbstractA survey was conducted to determine the frequency and abundance of plant parasitic nematodes in unirrigated fields of Alhama region (south-eastern Spain), mainly under wheat and barley, but also food and forage legumes and olive trees. Seventy-seven fields were sampled from a total area of 38,575 ha. Heterodera avenae was the most widespread species in the area, followed by Merlinius brevidens, Pratylenchus neglectus, Pratylenchus thornei, Meloidogyne artiellia and Zygotylenchus guevarai. Twenty-three other species of plant parasitic nematodes were found. Morphometrics of Paratrophurus acristylus, Paratylenchus sheri, P. nanus and P. similes from Southern Spain are provided. Paratylenchus israeliensis is proposed as a new junior synonym of P. sheri.
