Ev. Zakharov, Natural hybridization between two swallowtail species Parnassius nomion and Parnassius bremeri (Lepidoptera, Papilionidae) shown by RAPD-PCR, RUSS J GEN, 37(4), 2001, pp. 375-383
Genetic evidence for interspecific hybridization between Parnassius nonzion
and Parniassius bremeri in nature is presented. To demonstrate hybridizati
on between these species, RAPD analysis was used. By testing 25 decamer pri
mers, three and two diagnostic markers were revealed for P. nomion and P. b
remeri, respectively. Out of 28 animals examined, 4 were shown to be inters
pecific hybrids. According to the distribution of diagnostic markers, the i
nterspecific hybrids were intermediate with regard to the parental species.
Ecological and biological characteristics of two butterfly species that pr
omote their hybridization in nature are discussed.
