Resumo: Triatoma brasiliensis is the most important vector of Chagas disease in the semiarid zone of the Northeast of Brazil. Several authors have reported the occurrence of four chromatic patterns with morphological, ecological, and genetic differences. In order to determine the existence of cytogenetic differentiation between these chromatic forms, we analyzed their karyotypes and the chromosome behavior during the male meiotic process. Triatoma brasiliensis shows distinct and specific chromosome characteristics, which differ from those observed in all other triatomine species. However, no cytogenetic differences were observed between the four chromatic forms of T. brasiliensis. The lack of chromosome differentiation among them could indicate that the populations of this species are in a process of differentiation that does not involve their chromosomal organization.

Para verificar diferenças citogenéticas nessas populações, foram analisados seus cariótipos e o comportamento cromossomial durante o processo meiótico em exemplares machos. Observou-se que o T. brasiliensis mostra características cromossômicas distintas e específicas entre as quatro populações, diferindo daquelas observadas em outras espécies de triatomíneos. No entanto, diferenças citogenéticas não foram observadas entre as quatro populações de T. brasiliensis, o que poderia indicar que as referidas populações ainda se encontram em uma etapa inicial do processo de diferenciação, ainda não envolvendo a organização cromossomial.Reports in Public HealthCadernos de Saúde Pública2000-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1356Reports in Public Health; Vol. 16 No. 6 (2000): Supplement 2Cadernos de Saúde Pública; v. 16 n. 6 (2000): Suplemento 21678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1356/2700https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1356/2701Panzera, FranciscoPérez, RubenNicolini, PaulaHornos, SoniaCosta, JaneBorges, ÉrikaDiotaiuti, LiléiaSchofield, Christopher J.info:eu-repo/semantics/openAccess2024-03-06T15:26:23Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/1356Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:01:37.840409Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
