Several homeobox-containing genes related to Distal-less (Dlx/Dll) have been isolated from a wide variety of organisms and have been shown to function as developmental regulators. In Drosophila only one Distal-less gene has been identified so far, and in vertebrates many components of the Distal-less family have been characterized. This suggests that, during the evolution of the Chordate phylum, the Dlx genes arose from an ancestral Distal-less gene via gene duplication. Three Dll homeoboxes have been isolated from the protochordate Ciona intestinalis and their clustered arrangement has been described. Since Ciona is regarded as one of the most primitive extant chordates, …

Heliothis virescens, a member of the lepidopteran family, is of great importance to many people who rely on agriculture as a source of income because it is a pest of many important crops. Because H. virescens feeds on a broad array of hosts including cotton, tobacco, tomato, and soybean it has earned its place as a major nuisance in the United States. Heliothis subflexa is a close taxonomic relative of H. virescens, but the two species differ in that H. subflexa is a specialized herbivore that only feeds on plants in the genus Physalis. Studies have been performed to determine …
