SUMMARY:

The objective of this work was to evaluate the spatial distribution of the plaice scale (Praelongaortezia praelonga) in two cultivation systems in Northeastern Paraense, one consisting of the agroforestry system (Saf's) and the other by the conventional citrus cultivation system. The experimental area is located in the city of Capitão Poço, Microregion of Guamá, 200 km from Belém, PA. Evaluations were carried out at monthly intervals from September 2008 to August 2009, noting the presence or absence of the pest in both cultivation systems. The areas were georeferenced and geospatial analysis was performed through semivariogram models and kriging map interpolation. The model that best fit the data was the exponential range, ranging from 3,8 to 5,8 m for the conventional system and 3,3 to 7,3 m for the agroforestry system. Kriging maps showed the spatial distribution of the pest in the two studied areas, indicating a strong aggregation in both agroforestry and conventional systems. An exponential distribution behavior was also observed according to the adjusted models. From the results of geospatial analysis we can conclude that geostatistics was an important tool in the evaluation of P. Praelonga aggregate spatial distribution in both cultivation systems.
