Abstract
Dorsal mesotho-racic discs from 4-day Drosophila larvae transplanted into host larvae of the same age grow and differentiate to form 3 distinct regions: scutellar, dorso-lateral thorax and wing. In implants from 2^-3 day donors into 21/2, 3, or 4 day hosts, the wing was underdeveloped. Discs from eyD/ciD, D/lcL and D3 larvae into + hosts failed to affect the venation and flexion of the host wings. In the series of D3 implants in + hosts, all hosts carrying abdominal implants had + bristles. One host with a thoracic implant showed bristle deficiency. H2 ext. implants developed autonomously but gave no host effect. Venation defects can not be recognized in wing implants, but from the degree of growth and differentiation which the wing tissue attains it seems possible that a study of mutants which reduce wing size might yield significant data. The preliminary findings on bristle-bearing tissue strongly suggest that results on these tissues would have an experimental value comparable with that offered by eye disc transplantation.
