Chromosomes of Baryscapus silves-trii Viggiani et Bernardo, 2007 (Eulophidae) with n = 6 and 2n = 12 were studied using base-specific fluorochrome staining. Chromomycin A(3)/ 4', 6-diamidino-2-phenylindole (CMA(3)/DAPI) staining revealed a single paired CMA(3)-positive band within the diploid karyotype of B. silvestrii. This CG-rich segment apparently corresponds to the nucleolus organizing region (NOR). Certain features of karyotype evolution of parasitoids of the family Eulophidae are discussed.

Abstract
Chromosomes of Baryscapus silves-trii Viggiani et Bernardo, 2007 (Eulophidae) with n = 6 and 2n = 12 were studied using base-specific fluorochrome staining. Chromomycin A(3)/ 4', 6-diamidino-2-phenylindole (CMA(3)/DAPI) staining revealed a single paired CMA(3)-positive band within the diploid karyotype of B. silvestrii. This CG-rich segment apparently corresponds to the nucleolus organizing region (NOR). Certain features of karyotype evolution of parasitoids of the family Eulophidae are discussed.File in questo prodotto:
