Cytological investigations with regard to population dynamics of pine sawfly, Diprion pini L. (Hym.: Diprionidae)
Résumé
The occurrence of diploid males is demonstrated in the pine sawfly, Diprion pini. Inbreeding experiments and cytological investigations were designed to investigate this phenomenon. The cytological study shows an unexpected chromosome complement (n=14, 2n=28) in this diprionid species and suggests a karyotype evolution by centric fission. The expected significance of diploid males to D. pini population dynamics is discussed.
