title: [The b chromosome polymorphism in Armenian and Turkey populations of the grasshopper Eyprepocnemis plorans plorans (Charpentier) (Orthoptera, Acrididae, Eyprepocnemidinae)].
abstract: Karyotype analysis of the grasshopper Eyprepocnemis plorans samples derived from Armenian and Turkey populations was performed using C-banding technique. Chromosome polymorphism was associated only with B chromosomes that were revealed in all studied populations. Six new B chromosome morphotypes were described. Four morphotypes were found only in Armenian populations. One morphotype was revealed only in Turkey populations. One B chromosome morphotype was present in Armenian and Turkey populations. B chromosomes derived from Asian populations consisted mostly from C-positive regions. In some of the B chromosomes small C-negative regions were also registered. Morphotypes of the B chromosomes derived from Armenian and Turkey populations drastically differed from the B chromosomes described in the Iberian Peninsula and North African populations. In contrast to the B chromosomes from Armenian and Turkey populations the B chromosomes from Spain populations contained C-positive and C-negative regions alternated in their arms.
