Plant and animal studies

Samples of Apis mellifera ligustica from Emilia (northcentral Italy), samples of A. m. carnica from Austria and from northern Yugoslavia, and samples from Friuli (northeast Italy), regarded as a zone of hybridization, were assayed for allozyme polymorphism. Five loci were found to be polymorphic: Est-3, Est6, Mdh-l, Me, Pgm. Est-6 was used for the first time in a wide population study of A. mellifera. Among the polymorphic loci reported to date, Est-6 seems to be the more distinctive between A. m. ligustica and A. m. carnica. By a distance Wagner analysis of electrophoretic data, the samples of the two races were separated into two clearly distinct phenogram clusters. Friuli samples were clustered in an intermediate position.
