Abstract

The meiotic formula of the European spruce beetle, Dendroctonus micans (Kugelann), is 10 AA + Xyp in males and 10 AA + XX in females. This karyotype is different from the morphologically similar Dendroctonus punctatus LeConte (14 AA + Xyp), which is consistent with the taxonomic validity of both species. The chromosome number found in D. micans, added to karyological data from other species of the genus Dendroctonus Erichson, suggest that the karyological diversification within this genus may have occurred in two directions: one toward more southerly latitudes in North America and the other toward Europe and Asia.

Résumé

La formule méiotique de dendroctone de l’épicéa, Dendroctonus micans (Kugelann), est 10 AA + Xyp chez les mâles et 10 AA + XX chez les femelles. Cette formule méiotique est différente de celle de l’espèce conspécifique Dendroctonus punctatus LeConte (14 AA + Xyp), ce qui confirme la validité taxonomique des deux espèces. De plus, le nombre de chromosomes trouvés chez D. micans, en combinaison avec les karyotypes des autres espèces du genre Dendroctonus Erichson suggère que la diversification karyotypique du genre s’est produite selon deux modalités : d’une part en direction de latitudes plus méridionales en Amérique du Nord, d’autre part vers l’Europe et l’Asie.
