| cytogenetics as a tool for triatomine species distinction (hemiptera-reduviidae). | several cytogenetic traits were tested as species diagnostic characters on five triatomine species: rhodnius pictipes, r. nasutus, r. robustus, triatoma matogrossensis and t. pseudomaculata. four of them are described for the first time. the detailed analysis of the meiotic process and the application of c-banding allowed us to identify seven cytogenetic characters which result useful to characterize and differentiate triatomine species. | 1992 | 1343644 |
| an insight into the sialotranscriptome of triatoma matogrossensis, a kissing bug associated with fogo selvagem in south america. | triatoma matogrossensis is a hemiptera that belongs to the oliveirai complex, a vector of chagas' disease that feeds on vertebrate blood in all life stages. hematophagous insects' salivary glands (sgs) produce potent pharmacologic compounds that counteract host hemostasis, including anticlotting, antiplatelet, and vasodilatory molecules. exposure to t. matogrossensis was also found to be a risk factor associated with the endemic form of the autoimmune skin disease pemphigus foliaceus, which is d ... | 0 | 22665609 |
| evolutionary relationships of the triatoma matogrossensis subcomplex, the endemic triatoma in central-western brazil, based on mitochondrial dna sequences. | the phylogenetic relationships among species of triatoma matogrossensis subcomplex (t. baratai, t. guazu, t. matogrossensis, t. sordida, t. vandae, and t. williami) was addressed by using fragments of cytochrome oxidase i (coi), 16s rdna (16s), and cytochrome b (cytb) through bayesian and parsimony analyses. we did not recover a monophyletic t. matogrossensis subcomplex, and their members were found clustered in three strongly supported clades, as follows: i) t. jurbergi + t. matogrossensis + t. ... | 2013 | 24002487 |
| chromosomal characteristics and distribution of constitutive heterochromatin in the matogrossensis and rubrovaria subcomplexes. | since 1966 the triatomines were grouped in complexes and specific subcomplexes. although the complex and subcomplexes not have taxonomic importance, should be monophyletic groups and cytogenetic tools have proved to be of great importance to characterize these species groupings. based on this, this paper aims to describe the chromosomal characteristics and heterochromatic pattern of matogrossensis and rubrovaria subcomplexes, in order to contribute to the taxonomic and evolutionary relationships ... | 2015 | 25917494 |
| [observations on oviposition, hatching and the life span of triatoma matogrossensis leite & barbosa, 1953 (hemiptera, reduviidae) as a function of their feeding on pigeons and rabbits]. | a laboratory study was carried out concerning the influence of two kinds of blood-meal on egg laying, egg hatching and life span of triatoma matogrossensis. 68 couples in 4 different groups with 20, 12, 20 and 16 individuals of each sex per group were formed. maintained under laboratory conditions groups a1 and a2 were fed on pigeons and groups c1 and c2 were fed on rabbits. in relation to egg laying the best results were found in group a1. no differences on egg hatching were found between the g ... | 1998 | 9662963 |
