Karyotypic data on weevils (Coleoptera, Curculionidae)
Languages of publication
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.
