SUMMARY:

The Brazilian Amazon has a large number of varieties of palm trees, family Areacaceae, which are of great ecological and economic importance, with species that are of great use for its local population. The state of Pará has high productive potential for the cultivation of coconut and oil palm, as it has the necessary climatic conditions for its development. However, some pests and diseases of these palm trees become limiting factors for their production, with significant losses when there is no effective method of controlling these. Therefore, the present work aims to (i) analyze the spatial and temporal distribution of Phytomonas-wilt-disease in commercial coconut orchards, in the municipality of Moju / PA, from 2004 to 2016; and (ii) to analyze the spatial and temporal distribution of the incidence of Rhynchophorus Palmarum in commercial oil palm plots in the municipality of Acará / PA. The areas selected for the study are located in the state of Pará (Brazil) and consist of two commercial plantations, one of which is the coconut palm plantation located in the municipality of Moju and the other palm oil plantation located in the municipality of Acará. The sampling of Phytomonas-wilt-disease in coconut trees consisted of monthly evaluations from 2004 to 2016, in which each sick plant was identified and counted. And the sampling of the R. palmarum insect was carried out by accounting for adult insects, in bucket-type traps with aggregation pheromone, being evaluated monthly from June 2013 to May 2014. At the end of the samplings, geospatial databases were created, with spatial coordinates (latitude and longitude) of the variables evaluated for carrying out the analyzes to determine the spatial distribution and making incidence maps of sick plants and pest insects. The spatial distribution of both Phytomonas-wilt-disease and R. palmarum were considered aggregated. The maps of spatial distribution of kriging and LISA cluster indicate that the areas of the edge of the planting block next to native vegetation are areas of higher incidence of the pest and the emergence of cases of disease, therefore, they must be taken into account when creating management tactics. pests and diseases.
