Lepidoptera associados a cultura da soja na Argentina, Brasil, Chile e Uruguai

The present research updates the systematic position and nomenclature of Lepidoptera associated with soybean crops in Argentina, Brazil, Chile and Uruguay Scientific literature lists 69 species of Lepidoptera feeding on soybean plants. These species are representatives of the Superfamilies Noctuoidea (31), Pyraloidea (13), Hesperioidea (12), Tortricoidea (5), Geometroidea (5), and Bombycoidea (3). Diversity of Lepidoptera associated to crop, injury in different parts of the plant, and changes in species composition are discussed considering the changes in plant disease management, introduction of plants expressing Btproteins, and the recent introduction of Helicoverpa armigera (Hubner) as a new crop pest. Key words: caterpillars, inventory taxonomy, systematic, lepidopterous pests. O presente estudo atualiza a posicao sistematica e a nomenclatura dos lepidopteros associados com a cultura da soja na Argentina, Brasil, Chile e Uruguai. A literatura cientifica relaciona 69 especies de Lepidoptera cujas larvas se alimentam de soja. As especies incluem representantes das Superfamilias Noctuoidea (31), Pyraloidea (13), Hesperioidea (12), Tortricoidea (5), Geometroidea (5), and Bombycoidea (3). A diversidade dos lepidopteros associados com a cultura, as injurias em diferentes partes da planta e alteracoes na composicao das especies sao discutidas considerando mudancas no manejo de doencas da cultura, a introducao de plantas expressando proteinas Bt e a recente introducao de Helicoverpa armigera (Hubner) como uma nova praga da soja. Palavras-chave: lagartas, inventario, taxonomia, sistematica, lepidopteros-praga.
