Differentiation of Aedes atlanticus and Aedes tormentor by restriction fragment length polymorphisms of the second internal transcribed spacer.

Using novel DNA sequence data, we designed a restriction enzyme assay that distinguishes Aedes atlanticus and Ae. tormentor, based on size polymorphisms. The restriction endonuclease Hpy188I digests polymerase chain reaction-amplified 2nd internal transcribed spacer products once for Ae. atlanticus and twice for Ae. tormentor, thus providing a useful method for identifying adult female collections that are generally considered morphologically indistinguishable.
