Population genetics of the parthenogenetic gall waspDiplolepis rosae (Hymenoptera, Cynipidae)

  • B. Stille


The genetic diversity of the parthenogenetic gall waspDiplolepis rosae is investigated by a survey of 26 enzyme loci.D. rosae, which is confined to roses (Rosa) and reproduces by obligate gamete duplication, was sampled from five host-plant species in southern Sweden. Additional galls were obtained from Germany and Greece. Eight genotypes were determined on the basis of nine variable loci. The genotypes are not correlated to host-plant species, and in some cases differ in geographical distribution, indicating adaptation to climatic factors. The consequences of gamete duplication for the genetic diversity and ecology ofD. rosae are discussed.
