Studies on the Chromosomes of Indian Coleoptera

V. On the Cytology of Hoplobrachium asperipenne Fairm. (Tenebrionidae: Amarygminae), Epilachna septima Dieke (Coccinellidae: Epilachninae), and Caryedon gonagra (Fabr.)

抄録

Three species, Hoplobrachium asperipenne, Epilachna septima, Caryedongonagra belonging to the family Tenebrionidae, Coccinellidae, Bruchidae respectively have been cytologically investigated. They show diploid numbers 2n=22, 20, 18 respectively. Hoplobrachium shows an increase from the modal number while the Epilachna and Caryedon are characteristic to their generic karyotypes. The chro-mosomal distribution during meiosis in the three families, has been dealt with.
