The results of karyological studies of Curculionidae published since 1978 are summarized. Chromosome complements for 189 species are presented. Diploid chromosome number 2n=22, and meioformula n%=10+Xyp is the most characteristic chromosome number of weevils occuring in more than one-third of species examined karyologically. In Curculionidae there is a clear tendency towards symmetrization of karyotypes.
