Abstract

The objective of this study to monitor the fluctuation populational of the nematode Bursaphelenchus cocophilus. The survey was conducted
in two experimental areas being a savanna and other forest in Roraima. For the study was necessary to carry out the capture of insect
vectors of the nematode Rhynchophorus palmarum and Metamasius hemipterus through the bucket traps containing Rhynchophorus aggregation pheromone and food bait (sugarcane). For the extraction and finding the number of nematodes present in insects, was used to Baermann
funnel method. The fluctuation of the nematode data were submitted to descriptive statistics and correlation analysis using Statistica 7.0
computer application. The density of B. cocophilus in R. palmarum is greater in forest environment. The population density of B. cocophilus
in M. hemipterus not differ between savanna and forest environments. The frequency of nematodes between males and females in R.
palmarum was similar. The population density of the species B. cocophilus in the species of Rhynchophorus palmarum and M. hemipterus in savanna and forest environments is not directly correlated with rainfall, average temperature and relative humidity.
