C-banded Karyotype of Psyllid Species Aphalara calthae (L.) (Psylloidea, Homoptera, Insecta)

抄録

C-banding pattern of holokinetic chromosomes in Aphalara calthae is reported. The large C-positive regions are shown to be localized on the telomeres of the meiotic metaphase chromosomes. Two pairs of autosomes and the X-chromosome bearing blocks of C-heterochromatin on both telomeres. Nine pairs of autosomes have a block on one telomere while one chromosome pair shows no C-bands.
