Abstract: Rhynchophorus palmarum, the palm weevil, has been reported as a pest of palms and sugarcane plants. The Red Ring Disease is an infectious plant disease caused by nematodes. The etiological agent, Bursaphelencus (Rhadinaphelencus) cocophilus (Nematoda: Aphelenchoididae), completes its life cycle within 9 to 10 days inside the palm tree. The main symptom is a permanent wilting of the plant aerial parts. Previous studies stated that B. cocophilus cohabits with other nematodes the gut of R. palmarum. The aim of this study is to identify nematodes collected from palm weevil found in coconut plantations from the north of the Rio de Janeiro State. Light (LM) and scanning electron microscopy (SEM) analyses were carried on samples of infected R. palmarum and fragments and fresh juice of infected plants with B. cocophilus. Observations of R. palmarum fecal material made by LM and SEM showed three species cohabiting these samples, being also present in fresh juice and fragments of infected coconut tree: B. cocophilus, Teratorhabditis palmarum (Nematoda: Rhabditidae) and Diplogasteritus sp (Nematoda: Diplogasteridae). These findings confirm previous studies, which related that R. palmarum own a varied nematode fauna. Nematodes associated to B. cocophilus probably could be co-participates of the etiology of the Red Ring disease.
