Conteúdo: 	Abstract. This paper presents an automatic method based on digital image processing for analyzing the leaves of soybean plants hosting whiteflies. The method is capable not only of counting and measuring whitefly nymphs and adults, but it is also capable of counting and measuring empty whitefly exoskele- tons, as well as lesions that may be present in the leaf. The approach used in the algorithm is very simple, employing color model transformations to isolate the elements of interest in the image, and mathematical morphology to fine tune the results. This approach provides very accurate estimates under the tested conditions, and preliminary tests have shown that the algorithm is flexible enough to be used in other situations with only a few minor adjustments.
