PLANT-PARASITIC NEMATODES ASSOCIATED WITH TROPICAL AND SUBTROPICAL CROPS IN SOUTHERN SPAIN
AbstractA survey on the most representatives tropical and subtropical crops in southern Spain was carried out during autumn 1989 and spring 1990 to determine the distribution and population density of plant parasitic nematodes in soil and roots. Migratory ectoparasites were the most abundant and widespread. The predominant ectoparasitic species were Mesocriconema curvatum, Helicotybnchus digonicus, Criconema mutabile, Criconemoides amorphus, Ogma civellae, Helicotylenchus dihystera and Xzphinema pachtaicunz. Important endoparasitic and semiendoparasitic nematodes were found in soil and root samples of papaya (Meloidogynejavanica and Rotylenchulus renfomnis) and banana (M. jaknica and Pratylenchus uulnus).
