Abstract
Karyotypes of Leptopilina boulardi (Barbotin, Carton et Keiner-Pillault, 1979) (n = 9), L. heterotoma (Thomson, 1862) (n = 10), L. victoriae Nordlander, 1980 (n = 10) and Ganaspis xanthopoda (Ashmead, 1896) (n = 9) (Hymenoptera, Figitidae) were studied using DNA-binding ligands with different base specificity [propidium iodide (PI), chromomycin A3 (CMA3) and 4′,6-diamidino-2-phenylindole (DAPI)], and fluorescence in situ hybridization (FISH) with a 45S rDNA probe. Fluorochrome staining was similar between the different fluorochromes, except for a single CMA3- and PI-positive and DAPI-negative band per haploid karyotype of each species. FISH with 45S rDNA probe detected a single rDNA site in place of the bright CMA3-positive band, thus identifying the nucleolus organizing region (NOR). Chromosomal locations of NORs were similar for both L. heterotoma and L. victoriae, but strongly differed in L. boulardi as well as in G. xanthopoda. Phylogenetic aspects of NOR localization in all studied species are briefly discussed.
