| biology of triatoma klugi carcavallo, jurberg, lent & galvão 2001 (heteroptera: reduviidae) under laboratory conditions: effects of distinct blood sources and susceptibility to trypanosoma cruzi and trypanosoma rangeli. | the life cycle of triatoma klugi carcavallo, jurberg, lent & galvão 2001 was compared under laboratory conditions using two groups of the f1 generation obtained from field-collected bugs. among the 100 nymphs weekly fed on mice (group a) or chicken (group b), 77% of group a and 67% of group b reached the adult stage, and the mean time from the first nymphal stage to adult was 190.08 +/- 28.31 days and 221.23 +/- 40.50, respectively. the average span in days for each stage per group and the numbe ... | 2002 | 12118296 |
| comparative study of the stridulatorium sulcus, buccula and rostrum of nymphs of triatoma klugi carcavallo et al, triatoma vandae carcavallo et al and triatoma williami galvão et al (hemiptera: reduviidae). | ultrastructural analysis of the ventral region of the head--rostrum, buccula and stridulatorium sulcus--of 1st, 3rd and 5th instars of triatoma klugi carcavallo et al, triatoma vandae carcavallo et al, and triatoma williami galvão et al, are described in here. morphological differences in the analyzed structures for all three triatoma species studied were detected under scanning electron microscopy, allowing their grouping by their morphological similarities. species-specific differences at each ... | 2010 | 20305897 |
| a novel monoclonal antibody that binds to hemocytes from shrimps and oysters. | the monoclonal antibody (mab) lito-1 was produced from a stable hybridoma cell line generated by the fusion of ns1 myeloma cells with spleen cells isolated from balb/c mice immunized with a paraformaldehyde-fixed hemocyte suspension of litopenaeus vannamei. this mab reacted with all three hemocyte subtypes, but no reaction was observed with components of plasma. immunohistochemistry assays demonstrated that lito-1 was very effective in specifically distinguishing hemocytes infiltrated in several ... | 2010 | 20443709 |
| 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 |
| mitochondrial gene confirms the specific status of triatoma pintodiasi jurberg, cunha, and rocha, 2013 (hemiptera, triatominae), an endemic species in brazil. | chagas disease is most frequently transmitted to humans through contact with feces of insects from the triatominae subfamily. in brazil, there are 65 species of triatomines distributed throughout the country's 27 states. among the species in the state of rio grande do sul, triatoma rubrovaria, triatoma oliveirai, triatoma pintodiasi, triatoma klugi, triatoma carcavalloi, and triatoma circummaculata (with the addition triatoma limai, which is endemic to argentina) form the t. rubrovaria subcomple ... | 2017 | 27821685 |
