Com o intuito de gerar subsídios para realização de estudos genéticos em formiga cortadeira (especificamente Atta sexdens), caracterizou-se o padrão de amplificação de DNA gerado por primers ISSR. Para tanto, operárias médias de A. sexdens tiveram DNA genômico extraído utilizando a cabeça, mesossoma e pernas. Os padrões de amplificação foram analisados em géis de agarose 2%. Dentre os 23 primers ISSR testados 17 geraram produtos de amplificação (sendo 12 destes primers classificados como “tipo ideal” e cinco como “tipo razoável”). O percentual de polimorfismo variou entre 20% (primer TriAGA3’RC) e 100% (primer DiCA3’YG). Os resultados atestam que os primers ISSR selecionados apresentam um grau de polimorfismo considerável e, portanto, são adequados para estudos de diversidade genética em formigas cortadeiras, especialmente para A. sexdens.
