Research output: Contribution to journalArticlepeer-review


To investigate the potential for natural interspecific hybridization in the Rhagoletis pomonella group of sibling fruit fly species, an attempt was made to hybridize R. pomonella, the apple maggot fly, with R. cornivora, a non‐pest feeding on dogwoods. Laboratory hybridization was difficult, with only five F1 hybrids produced. Electrophoretic analysis of the hybrids confirmed their hybrid origin. Allele frequency data for three diagnostic loci in up to 5,596 individuals of the parental species, gathered from published and unpublished studies, indicate that the two sibling species hybridize in nature very infrequently, if at all. 1993 The Netherlands Entomological Society
