Meiotic behavior and karyotypic variation in Acledra (Pentatomidae, Heteroptera)

P. J. Rebagliati and Mola, L. M., Meiotic behavior and karyotypic variation in Acledra (Pentatomidae, Heteroptera), vol. 9, pp. 739-749, 2010.

Acledra comprises 15 taxonomically identified species, most of which are crop pests. This is the first cytogenetic study of species of this genus. Acledra kinbergii and A. modesta showed the modal number of the Pentatomidae (2n = 14 = 12 + XY), while A. bonariensis had a reduced complement (2n = 12 = 10 + XY), with a markedly larger autosomal pair.

Pattern of silver nitrate-staining during meiosis and spermiogenesis in testicular lobes of Antiteuchus tripterus (Heteroptera: Pentatomidae)

H. V. Souza, Castanhole, M. M. U., Bicudo, H. E. M. C., and Itoyama, M. M., Pattern of silver nitrate-staining during meiosis and spermiogenesis in testicular lobes of Antiteuchus tripterus (Heteroptera: Pentatomidae), vol. 7, pp. 196-206, 2008.

The pattern of silver nitrate (Ag)-staining differed among testicular lobes of Antiteuchus tripterus. In general, these differences are in regard to the number, size, shape, coloring intensity, and location of the stained bodies or masses, observed during meiosis and spermiogenesis. These characteristics were similar in lobes 1-3. Lobes 4-6, however, differed from each other and from lobes 1-3 as well.
