This protocol provides details of a simple, reliable, inexpensive and rapid method for DNA isolation from different types of leaf-cutting ant tissue samples. The method involves tissue grinding, buffer addition and successive steps of protein purification and DNA precipitation. Different ant tissues were evaluated for DNA extraction. The DNA yield ranged from 1.6 to 10.5 μg depending on the initial ant tissue sample. The procedure provides suitable amounts of DNA to be used in PCRs. Amplifications using DNA from each ofthe tissues evaluated were able to amplify a fragment of the mitochondrial COI gene of approximately 800 bp from both Atta an Acromyrmex species. This protocol provides a simple DNA isolation method for molecular identification and phylogenetic studies of leaf-cutting ants.
