Karyotype, heterochromatin distribution and meiosis of Zabrotes subfasciatus (Bohemann) (Coleoptera: Chrysomelidae, Bruchinae) Neotropical Entomology
Corrêa,Ronan X.; Pompolo,Sílvia G.; Santos,Igor S.; Silva,Janisete G.; Costa,Marco A..
Zabrotes subfasciatus (Boh.) has been extensively studied in its agronomic and biochemical aspects due to its importance as a damaging insect to leguminous grains during storage. The few cytogenetic studies published on this species yielded conflicting results. In this study, the karyotype was analyzed in order to accurately describe the chromosome C-banding patterns and meiosis. The brain ganglion at the prepupa and the adult and pupal testes were analyzed. All individuals had 26 chromosomes in both brain ganglion and spermatogonic mitotic metaphases. These chromosomes were classified as follows: the 12th pair and the Y chromosome were telocentric; the X chromosome was acrocentric; the 4th and 5th pairs were submetacentric; and the remaining pairs were...
