Abstract

The male meiotic karyotypic formula of Conophthorus coniperda (Schwarz) (Coleoptera: Scolytidae) is 9AA + XY. This karyotype differs from C. resinosae Hopkins and C. banksianae McPherson, both of which have the karyotypic formula of 8AA + XY. Supernumerary chromosomes were found in different populations of C. resinosae and C. banksianae but were absent in C. coniperda. No geographic variation in the karyotypes of the three species was observed. The karyotypic formulae confirm the designations of C. coniperda and C. resinosae by morphological characters, but do not support the designation of C. banksianae as a distinct species.

Résumé

En division méiotique, la formule caryotypique des mâles de Conophthorus coniperda (Schwarz) (Coleoptera : Scolytidae) est 9AA + XY, alors celle que C. resinosae Hopkins et C. banksianae McPherson est la même soit, 8AA + XY. Des chromosomes surnuméraires furent localisés seulement dans les populations de C. resinosae et de C. banksianae. Aucune variation géographique n’a été observé dans les caryotypes des trois espèces. Les formules caryotypiques différentes de C. coniperda et C. resinosae confirment l’existence de caractères morphologiques distincts entre ces deux espèces. Par contre, l’absence de différences entre les caryotypes de C. resinosae et C. banksianae ne supporte pas la reconnaissance de C. banksianae comme une espèce différente de C. resinosae.
