Sex chromosome differentiation in Belostoma (Insecta: Heteroptera: Belostomatidae) [PDF]
Genetics and Molecular Research, 2012 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 this genus involves agmatoploidy and simploidy; there are also different sex chromosome systems.

The pace and shape of ant ageing. [PDF]
Biol Rev Camb Philos SocABSTRACT Ants have been proposed as good models to study ageing and the effects of extrinsic mortality because of their long lifespans and plasticity of ageing within species. We discuss how age‐dependent extrinsic mortality might influence queen lifespan, and how the effect of age‐independent extrinsic mortality needs further study, accounting for ...

The significance of cytogenetics for the study of karyotype evolution and taxonomy of water bugs (Heteroptera, Belostomatidae) native to Argentina [PDF]
, 2013 Male meiosis behaviour and heterochromatin characterization of three big water bug species were studied. Belostoma dentatum (Mayr, 1863), B. elongatum Montandon, 1908 and B. gestroi Montandon, 1903 possess 2n = 26 + X1X2Y (male).
