Sex chromosome differentiation in Belostoma (Insecta: Heteroptera: Belostomatidae)
(Funpec-editora, 2012-01-01)
Belostoma, a genus of the family Belostomatidae, includes species of great ecological importance as biocontrol agents. Few species of these species have been the subject of cytogenetic analyses. Karyotypic evolution in ...

Astylus variegatus (Coleoptera, Melyridae): Cytogenetic study of a population exposed to agrochemical products
(Sociedade Brasileira de Genética, 2007-01-01)
In this work we describe the cytogenetic analyses performed in specimens of Astylus variegatus (Germar, 1824) collected in two localities: one area of natural vegetation and one of agricultural crops, where agrochemical ...
Conventional and ultrastructural analyses of the chromosomes of Discocyrtus pectinifemur (Opiliones, Laniatores, Gonyleptidae)
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Among the Opiliones, species of the suborders Cyphophthalmi, Eupnoi, Dyspnoi and Laniatores have shown very diverse diploid chromosome numbers. However, only certain Eupnoi species exhibit XY/XX and ZZ/ZW sex chromosome ...
Pattern of nucleolar activity during spermiogenesis in triatomines (Heteroptera, Reduviidae) as analysed by silver staining
(Faculty Press, 1997-01-01)
Nucleoli are the sites of biosynthesis of ribosomal precursors. In this work the nucleolar activity at interphase and the meiotic cells of the testis in five species of triatomines were analysed by means of silver staining. ...

Natural diffusers for the treatment of residual water in an aerobic system
(2008)
Since the advent of the surface microspreading technique for synaptonemal complex analysis, increasing interest in describing the synapsis patterns of chromosome abnormalities associated with fertility of domestic animals ...
