Abstract
Genetic polymorphism at about twenty enzyme loci in one mainland and in six differentially isolated island populations of Philaenus spumarius (L.) was studied by starch gel electrophoresis. The populations have different average degrees of heterozygosity, so that the most isolated population is the least polymorphic. The differences in heterozygosity seem to be correlated to the size of the population and the degree of isolation from other populations. With a single exception, the most common allele in each locus is the most common one everywhere. The results are compared with the differences observed in the color polymorphism of Philaenus island populations. The allele frequencies of enzyme loci are maintained by selection; the fact that the prevalent allele is the same in all populations may be due to selection and founder principle.
