Análise espaço-temporal de mosca-branca Bemisia tabaci (Genn., 1889) biótipo B (Hemiptera: Aleyrodidae) na cultura da soja, no município de Paragominas - Pará
The objective of this study is to evaluate the progress of whitefly Bemisia tabaci biotype B infestation during the crops of 2015, 2016 and 2017, to identify between crops studied in which they increased or decreased infestation and in which month the infestation was more representative, to identify among the cultivars which one or which are most susceptible to the attack and to map the areas of incidence of the whitefly. The research to obtain the data was carried out in the municipality of Paragominas and the data were obtained from Defense Agency of the State of Pará according to the methodology based on a model predefined by the agency. Climatic data on rainfall (mm) for crops were obtained through a database of the Brazilian Agricultural Research Corporation meteorological station. For statistical analysis of data, a database was built into Microsoft Excel spreadsheets. Data were analyzed through regression analysis and compared by the Tukey and Scott & Knott test. For the preparation of the whitefly infestation maps, the Spatial Analyst extension in the ArcGIS 10.1 software was used. In the studied area, the month of April is the one with the highest incidence of the pest, the crop of 2017 presented greater infestation, the cultivar P99R03 RR was the most susceptible to the attack of whitefly, and the cultivars P98Y51 RR and FT PGM, were more resistant to whitefly (B. tabaci) biotype B than the other cultivars.
