“…The Triatominae subfamily includes 137 insect species (Galvão et al, 2003) divided into six tribes: Alberproseniini, Bolboderini, Cavernicolini, Linshcosteini, Rhodniini, and Triatomini. Eighteen triatomine genera have been described: Alberprosenia, Belminus, Bolbodera, Microtriatoma, Parabelminus, Cavernicolai, Linshcosteus, Psammolestes, Rhodnius, Dipetalogaster, Eratyrus, Hermanlentia, Meccus, Mepraia, Nesotriatoma, Paratriatoma, Panstrongylus, and Triatoma (Galvão et al, 2003).…”

Spermatogenesis and nucleolar activity in Triatoma klugi (triatomine, Heteroptera)

2008

Triatoma klugi is a Chagas disease vector in the Rio Grande do Sul State. Triatominae chromosomes are holocentric and sex chromosomes segregation is post-reductional. In this paper we describe the karyotype of male T. klugi and a meiotic analysis including the nucleolar behavior during spermatogenesis. Testis cells were analyzed after lactoacetic orcein and silver nitrate staining. Two autosomes and the heterochromosomes presented nucleolar activity (Ag-NORs) during diplotene-diakinesis. The analysis of metaphase I and II revealed a karyotype with 2n = 20+XY. In metaphase I a prominent nucleolar mass was observed in the cell periphery and small silver grains were detected in metaphase II. During anaphase, the chromosomes segregated in parallel and a typical holocentric late migration behavior was observed. The restoration of the nucleolus was an important feature in this phase. During telophase nucleolar masses persisted and in early spermiogenesis the spermatids presented a small peripheral mass until elongation. The present study is a contribution to the study of chromatin behavior and nucleolar persistence in meiosis.

“…In Brazil, there are eight genera of Triatominae: Alberprosenia, Belminus, Cavernicola, Eratyrus, Microtriatoma, Panstrongylus, Parabelminus, Psammolestes, Rhodnius, and Triatoma (5) (6) . In the State of Acre, researchers have reported the occurrence of four species of triatomines, namely, Rhodnius robustus (7) , Rhodnius pictipes, Panstrongylus geniculatus (8) , and Eratyrus mucronatus (9) .…”

Introduction: This paper reports, for the fi rst time, the presence of Rhodnius montenegrensis in the State of Acre, Brazil. Methods: Two female R. montenegrensis were collected in a dwelling in the rural area of Rio Branco, Acre, Brazil. Results: The occurrence of this species was confi rmed, and the number of Triatominae species in the State of Acre increased from four to fi ve. Conclusions: Further studies should be performed to reach a clearer understanding of the ecology of this arthropod, its possible role in transmitting Chagas' disease and rangeliosis, and its current geographical distribution in the region.

“…At the moment, 141 species of Triatominae are described in the New World (Galvão et al 2003, Galvão & Angulo 2006, Costa et al 2006, Bérenger & Blanchet 2007, Costa & Félix 2007, Martinez et al 2007, Sandoval et al 2007. The reduction in T. infestans (Klug) populations in residences has created an available niche for other vectors and the tendency for peridomestic or wild species to occupy these available niches in Paraguay and Brazil has been demonstrated (Dias 1988, Ruas Neto & Krug 1995, Rojas-de-Arias 1996.…”

-Triatoma guasayana (Wygodzinsky & Abalos) is a peridomestic triatomine with epidemiological importance in Bolivia, that may play an important role in the transmission of Trypanosoma cruzi (Chagas). In this study, two parameters of vectorial capacity were evaluated: the interval of feeding-defecation time and metacyclogenesis, in adult males and females and nymphal instars II to V of T. guasayana with comparisons with Triatoma infestans (Klug) and T. sordida (Stal). The results showed a close relationship between ingestion of blood and beginning of defecation. Values were negative in T. infestans, and T. sordida for instars II, III, IV, and V and also males and females but were positive in female T. sordida. Triatoma guasayana showed only negative values for instar II. Adults and nymphs began defecation as soon as they had finished feeding and required an average of 29.8 min. The analysis of metacyclogenesis showed that T. guasayana was superior to T. infestans and T. sordida. However, the vectorial effectiveness of T. guasayana was significantly affected regarding the percentage of metacyclic trypomastigotes during instars III to V and showed a progressive increase. Females had higher proportions despite their ingestion being half that of T. infestans. The different instars of T. guasayana had a higher parasitic load than those of T. sordida and, although ingestion was 1/3 of that of female T. infestans, there was a progressive increase in metacyclic trypomastigotes in the different nymphal stages of T. guasayana that decreased in adults.
