| karyotype and spermatogenesis in triatoma lenti (hemiptera: triatominae), a potential chagas vector. | all species of triatominae are susceptible to infection by trypanosoma cruzi (kinetoplastida: trypanosomatidae) and consequently, potential insect vectors of chagas disease. currently, there are 140 known species of triatomine bugs, which can be grouped into specific species complexes. the species triatoma lenti (hemiptera: triatominae) is found only in brazil and is considered a potential vector of chagas disease. we karyotyped male t. lenti and examined its spermatogenesis in detail. the karyo ... | 2012 | 23315807 |
| triatominae survey (hemiptera: reduviidae: triatominae) in the south-central region of the state of bahia, brazil between 2008 and 2013. | triatomine surveillance in rural areas, artificial ecotypes, and natural ecotopes of the cities of caturama, ibipitanga, macaúbas, and seabra in the south-central region of the brazilian state of bahia was carried out between 2008 and 2013. natural infection by trypanosoma cruzi was evaluated in the specimens collected to monitor vectors of chagas disease. a total of 1,357 specimens were collected, and four species were identified: triatoma sordida (83%), triatoma lenti (16.4%), triatoma pseudom ... | 2015 | 25802433 |
| d2 region of the 28s rna gene: a too-conserved fragment for inferences on phylogeny of south american triatomines. | the brasiliensis complex is composed of five triatomine species, and different approaches suggest that triatoma lenti and triatoma petrochiae may be the new members. therefore, this study sought to analyze the phylogenetic relationships within this complex by means of the d2 region of the 28s rna gene, and to analyze the degree of polymorphism and phylogenetic significance of this gene for south american triatomines. phylogenetic analysis by using sequence fragments of the d2 domain did not allo ... | 2016 | 27382073 |
| cross-mating experiments detect reproductive compatibility between triatoma sherlocki and other members of the triatoma brasiliensis species complex. | phylogenetic approaches based on mitochondrial dna variation (fragments of cyt b and 16s ribosomal rna) have revealed triatoma sherlocki as the most recent species addition to the triatoma brasiliensis species complex; a monophyletic group which includes t. brasiliensis, triatoma melanica, and triatoma juazeirensis. t. sherlocki is the most differentiated among all species of this complex: it is unable to fly, possesses longer legs than the other members, and has reddish tonality in some parts o ... | 2013 | 23850508 |
