| vector capacity of members of triatoma brasiliensis species complex: the need to extend chagas disease surveillance to triatoma melanica. | we conducted a lab-based comparative study on vector capacity features of two species of triatomines: triatoma brasiliensis and t. melanica. both are members of the t. brasiliensis species complex. the former is the most important chagas disease vector in the northeastern region of brazil. to date, no transmission via t. melanica has been recorded. immature insects exhibited distinct intermoult periods without a direct relationship to a given species. females of t. brasiliensis consumed an avera ... | 2016 | 27232124 |
| does triatoma brasiliensis occupy the same environmental niche space as triatoma melanica? | triatomines (hemiptera, reduviidae) are vectors of trypanosoma cruzi, the causative agent of chagas disease, one of the most important vector-borne diseases in latin america. this study compares the environmental niche spaces of triatoma brasiliensis and triatoma melanica using ecological niche modelling and reports findings on dna barcoding and wing geometric morphometrics as tools for the identification of these species. | 2015 | 26156398 |
| are members of the triatoma brasiliensis (hemiptera, reduviidae) species complex able to alter the biology and virulence of a trypanosoma cruzi strain? | trypanosoma cruzi is the causative agent of chagas disease, transmitted to humans and mammals by blood-sucking hemipteran insects belonging to the triatominae subfamily. the two main genotypes of t. cruzi (tci and tcii) differ in many characteristics concerning their genetic profile. despite the extensive literature on vectors and the etiologic agent, several interactive aspects between these two elements of chagas disease are still waiting to be further clarified. here, biological and histologi ... | 2015 | 26013138 |
| multiple mitochondrial genes of some sylvatic brazilian triatoma: non-monophyly of the t. brasiliensis subcomplex and the need for a generic revision in the triatomini. | multiple fragments of mitochondrial dna genes (cytochrome b, cytochrome oxidase i, and 16s rdna) were used to evaluate the phylogenetic relationships among triatoma melanocephala, triatoma tibiamaculata, triatoma vitticeps, and other members of triatoma brasiliensis subcomplex under a bayesian framework and maximum parsimony criterion. with the addition of new sequences of t. tibiamaculata and t. vitticeps, triatoma juazeirensis, triatoma melanica and the newly sequenced t. melanocephala, the th ... | 2014 | 24508245 |
| revalidation and redescription of triatoma brasiliensis macromelasoma galvão, 1956 and an identification key for the triatoma brasiliensis complex (hemiptera: reduviidae: triatominae). | triatoma brasiliensis macromelasoma is revalidated based on the results of previous multidisciplinary studies on the triatoma brasiliensis complex, consisting of crossing experiments and morphological, biological, ecological and molecular analyses. these taxonomic tools showed the closest relationship between t. b. macromelasoma and triatoma brasiliensis brasiliensis. t. b. macromelasoma is redescribed based on specimens collected in the type locality and specimens from a f1 colony. the complex ... | 2013 | 24037202 |
| 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 |

| ultrastructural localization of basic proteins and carbohydrates in male accessory glands of two triatoma species (hemiptera, reduviidae, triatominae). | the male accessory glands in triatoma are tubular and produce substances with some functions related to production of the spermatophore. in the current study, the cytochemistry of male accessory glands was evaluated in starved triatoma brasiliensis and adult triatoma melanica. the storage of carbohydrates and proteins in t. melanica male accessory glands occurs earlier than in t. brasiliensis. in addition, the occurrence of eletron-lucent granules without carbohydrates and proteins suggests that ... | 2011 | 21661307 |
