Abstract

An analysis was made of C-banded karyotype of Otiorhynchus corvus Boh. The results indicate that the chromosome number is 2n = 22 and n_??_ =10 + Xyp. All autosomes and the X chromosome are metacentric, the y is dot-shaped. The examined karyotype shows only pericentromeric position of constitutive heterochromatin in all autosomes and the X heterochromosome. The y has a greater segment of constitutive heterochromatin and the rest of it is euchromatic.
