Abstract: | - 1.1. Seven natural populations of Dacus dorsalis were analyzed for a dimeric esterase by means of horizontal starch-gel electrophoresis.
- 2.2. The electrophoretic phenotypes were governed by nine codominant Est-D alleles.
- 3.3. The commonest allele in all seven population samples was Est-D100 which encoded an electrophoretic band with intermediate mobility.
- 4.4. The distribution of EST-D phenotypes were in accordance with Hardy-Weinberg expectations.
- 5.5. There was no geographic variation in the distribution of Est-D alleles.
