Transplanted leg imaginal discs establish nerve connections with the appropriate neuromeres of the host's thoracic ganglion in the flySarcophaga bullata

Summary Ectopic transplantations of prothoracic leg imaginal discs of mature 3rd instar larvae ofSarcophaga bullata on to young prepupae resulted in the development of supernumerary legs. The nerves that connected these legs with the host's CNS projected in the appropriate neuromere of the thoracico-abdominal ganglion.Supported by the Natural Sciences and Engineering Research Council of Canada.
