Resumen
Wolbachia are intracellular bacteria that commonly infect arthropods. Its prevalence among ants of the genus Solenopsis is high. In the present study, the presence and distribution of these endosymbionts was examined among populations of Solenopsis spp. from Brazil. A phylogenetic analysis based on the wsp gene was conducted to infer the evolutionary history of Wolbachia infections within the populations surveyed. A high frequency of Wolbachia bacteria was observed among the genus Solenopsis, 51% of the colonies examined were infected. Incidence was higher in populations from southern Brazil. However, little genetic variability was found among different Wolbachia strains within supergroups A and B. Our findings also suggest that horizontal transmission events can occur through the social parasite S. daguerrei. © 2012 Elsevier Inc..

Genise, Jorge Fernando; Cuezzo, Fabiana del Carmen; Gonzalez, Mirta Gladys; Krause, M. (Birkhauser Verlag Ag, 2012-11-24)Although fire ants have been extensively studied, not much has been published about the structure and<br />building material of their nests and even less on the lining of chamber walls. Nests built in unconsolidated sandy ... -
