Exact age determination in laboratory and field-caught Drosophila Academic Article uri icon


  • A method to prepare and count daily growth layers in internal thoracic muscle attachments is described. Growth layers have been observed in five species in the laboratory and in five field-caught species-including Drosophila melanogaster and D. pseudoobscura. The growth layers do not vary with the genetic make up of individuals within a species, and are comparable between individuals of different species. However, a daily temperature cycle is required for the production of strong layers in laboratory stocks. © 1982.
