Abstract

The diploid chromosome number of the cotton boll weevil, Anthonomus grandis Boheman, is 44. Both C‐ and N‐banding techniques of mitotic cells demonstrated constitutive heterochromatin in the p arm of the eight largest chromosomes, the p arm of the X chromosome, and the centromeric region of autosomal groups A–D. Neither the y nor the group E autosomes appeared to contain constitutive heterochromatin. Supernumerary chromosomes were not found in the boll weevil. Restriction endonuclease banding of primary spermatocytes revealed a rod‐shaped Xy tetrad in which the X and y were terminally associated. The p arm of the large, submetacentric X was C‐band positive. While two of the autosomal tetrads were typically ring‐shaped in primary spermatocytes, the remaining 19 autosomal tetrads were rod‐shaped.
