Abstract : A survey was conducted to determine the plant parasitic nematodes associated with 10 tropical fruit: citrus (Citrus spp.), avocado (Persea americana), mango (Mangifera indica), banana and plantain (Musa spp.), guava (Psidium guajava), papaya (Carica papaya), pineapple (Ananas comosus), sapodilla (Manilkara zapota), grape (Vitis vinifera), passion fruit (Passiflora edulis var. flavicarpa). Eighteen genera of plant parasitic nematodes were found in association with these crops: Aphelenchoides, Aphelenchus, Criconemoides, Ditylenchus, Helicotylenchus spp., Hemicriconemoides, Meloidogyne spp. Paratylenchus, Peltamigratus, Pratylenchus, Psilenchus, Radopholus (R. similis), Rotylenchulus (R. reniformis), Trichodorus, Tylenchorhynchus, Tylenchus, Tylenchulus (T. semipenetrans) and Xiphinema. Helicotylenchus spp., R. reniformis, Meloidogyne spp., Pratylenchus, Paratylenchus and Tylenchorhynchus were the most numerous and widely distributed.
