|Description:||ABSTRACT: Native of Australia, Thaumastocoris peregrinus (Eucalyptus bronze bug) is a Eucalyptus insect pest which was firstly detected in Brazil in June 2008. Some studies have shown favorable areas for T. peregrinus population outbreaks in Brazil, based on georeferenced-crossing information using geographical information system (GIS). Despite that, it is crucial to both enhance the precision of methods used on georeferenced crossings and update information, in order to enable greater precision toward the identification of propitious areas for the occurrence of the insect. The objective of this study was to identify areas with favorable conditions to occurrence of Thaumastocoris peregrinus in Brazil, in at least one month in the year, based on national information of this insect-pest. Favorable conditions to the occurrence of the insect, the average climatic data from weather stations (2009-2018) and Eucalyptus crop areas in 2018 were considered. This information was used in GIS to obtain a zoning map indicating the favorable areas to the insect in at least one month in the year. The georeferenced-crossing technique used considered both spatial interpolation by Cokriging methods and by Inverse Distance Weighted (IDW). Results indicated the presence of propitious outbreaks for T. peregrinus occurring in differentiated months in the Southern, Southeastern, Midwestern and Northeastern geographic regions of the country, with lowest monthly aptitude noticed for the Northern region. Different sequential periods of favorability for occurrences from very high to medium intensities were identified.|
