Optimization of cytogenetic techniques in a model aphid, \kur{Diuraphis noxia} (Aphididae)

Several cytogenetical methods for investigation of karyotyp were used in an aphid species, Diuraphis noxia (Hemiptera: Aphididae). These methods (FISH with telomeric probe, FISH with rDNA probe, FISH with histone probe and silver staining) were optimized for application to a sister group Adelgidae, where they could be useful for better differentiation of species in particular stages of their complicated life cycle
