A fate map of the wing disc ofZaprionus vittiger (diptera).

Various fragments of the wing disc from third instar larvae ofZaprionus vittiger were implanted into mature host larvae. From the differentiated structures observed in the metamorphosed transplants, a fate map (anlage plan) was constructed which includes the primordia for the thoracic colored stripes and the anlagen for several thoracic bristle organs. Our present data forZ. vittiger andDrosophila melangaster are in accord with the fate map reported earlier forD. melanogaster, with the only exception that the medio-lateral orientation of the primordia in the wing disc is reversed.
