Stem borer Stromatium barbatum (F.) (Coleoptera: Cerambycidae) has emerged as a major pest in grapes
in India. In the present study, the chromosome number and basis of sex differentiation of S. barbatum are
described. Mitotic chromosome spreads were prepared by isolating and treating the gonads with colchicine
and staining with conventional Giemsa stain. Cytogenetical analysis revealed the events of chromosomal
evolution. The results revealed diploid chromosome number of 2n = 18+XO in male and 2n = 18+XX in
female. Presence of supernumerary chromosome in female, translocation and uncommon pairing behaviour
also were observed. The differences and similarities of the sexes are brought out.
