ABSTRACT:
The aim of this study was to conduct a survey on nematodes associated with five cultivated fruit trees growing in the Agroforestry System (AFS) of the municipality of Oiapoque, Amapá, Brazil. Rhizosphere samples were collected from three points at the base of murici (Byrsonima sp.), soursop (Annona muricata ), cupuaçu (Theobroma grandiflorum ), passion fruit (Passiflora sp.) and peach palm (Bactris gasipaes ) trees. Four species of phytonematodes were identified, namelyPratylenchus brachyurus, Helicotylenchus dihystera, Mesocriconema xenoplax and Rotylenchulus reniformis . The most prevalent and abundant species wasR. reniformis , which was found in the rhizospheres of passion fruit, cupuaçu, soursop, and peach palm. The first record in Brazil of the nematodeP. brachyurus , found in the roots of murici is reported here, and all of the nematode species identified here are the first records for fruit trees in the state of Amapá.
