| [the resistance of fasting and nutritional aspects of triatoma lecticularia (stal, 1859) (hemiptera, reduviidae, triatominae)]. | the resistance to fasting of triatoma lecticularia was studied in all phases of the life cycle and the insect weighed in different nutritional situations (fed, not fed, death after starvation). the temperature and humidity levels were also recorded. the nymphal phases showed increasing resistance to fasting as demonstrated by the following averages (days) 1st 45.84; 2nd 61; 3rd 88.74; 4th 123.44; 5th 162.30. upon the adult phase, the averages were similar to those of the 3rd stage for the male i ... | 1989 | 2520831 |
| beauveria bassiana (hyphomycetes) as a possible agent for biological control of chagas disease vectors. | beauveria bassiana (balsamo) vuillemin (isolate cg306) was tested on 3rd instars of 9 triatoma spp., 4 rhodnius spp., 2 panstrongylus spp. and dipetalogaster maxima (uhler) at 25 degrees c and 50% rh. quantitative sporulation of the fungus on cadavers was studied at 25 degrees c and 97% rh. mortality, estimates of survival time, and conidial production on cadavers differed significantly among the genera and species tested. panstrongylus herreri wygodzinsky, dipetalogaster maxima, triatoma pictur ... | 1998 | 9835689 |
| isobutyric acid from the brindley's glands of triatoma lecticularia. | the contents of the brindley's gland of triatoma lecticularia (stål) (heteroptera: reduviidae: triatominae) have been identified by gas chromatography-mass spectrometry as isobutyric acid. this compound is found in similar secretions from certain other members of the triatominae, and is suggested to play a role as a defensive pheromone and for intraspecies communication. | 2000 | 10757489 |
| molecular taxonomic study of chagas disease vectors from the phyllosoma, lecticularia, and rubrofasciata complexes. | the triatiominae (hemiptera: reduviidae) are hematophagous hemipters of importance because they transmit trypanosoma cruzi, the causal agent of chagas disease. the aim of this study was to define the possible relationships between species of the phyllosoma complex (triatoma mazzottii, triatoma pallidipennis, and triatoma longipennis) and species of other complexes present in mexico that have not been previously analyzed (triatoma lecticularia and triatoma rubida). in addition, it was determined ... | 2005 | 16103598 |
| a micro-spreading improvement for spermatogenic chromosomes from triatominae (hemiptera-reduviidae). | cytogenetics of triatomines have been a valuable biological tool for the study of evolution, taxonomy, and epidemiology of these vectors of trypanosoma cruzi. here we present a single microtube protocol that combines micro-centrifugation and micro-spreading, allowing high quality cytogenetic preparations from male gonadal material of rhodnius prolixus and triatoma lecticularia. the amount of cellular scattering can be modulated, which can be useful if small aggregates of synchronous cells are de ... | 2006 | 16862334 |
| biology of three species of north american triatominae (hemiptera: reduviidae: triatominae) fed on rabbits. | aspects related to hatching, lifetime, number of blood meals for molting, mortality, feeding time, and postfeeding defecation delay were evaluated and compared in each instar of three north american triatominae: triatoma gerstaeckeri, triatoma lecticularia and triatoma protracta, all of them fed on rabbits. no significant differences (p > 0.05) were found among the three species regarding mean hatching rate, which was close to 20 days. egg-to-adult development times were significantly shorter (p ... | 2007 | 18209930 |
| effect of the saliva from different triatomine species on the biology and immunity of tlr-4 ligand and trypanosoma cruzi-stimulated dendritic cells. | triatomines are blood-sucking vectors of trypanosoma cruzi, the causative agent of chagas disease. during feeding, triatomines surpass the skin host response through biomolecules present in their saliva. dendritic cells (dcs) play a crucial role in the induction of the protection to aggressive agents, including blood-sucking arthropods. here, we evaluated if salivary components of triatomines from different genera evade the host immunity by modulating the biology and the function of lps- or t. c ... | 2016 | 27938380 |
| trypanosoma cruzi infection prevalence and bloodmeal analysis in triatomine vectors of chagas disease from rural peridomestic locations in texas, 2013-2014. | protozoan pathogen trypanosoma cruzi (chagas, 1909) is the etiologic agent of chagas disease, which affects millions of people in latin america. recently, the disease has been gaining attention in texas and the southern united states. transmission cycle of the parasite involves alternating infection between insect vectors and vertebrate hosts (including humans, wildlife, and domestic animals). to evaluate vector t. cruzi parasite burden and feeding patterns, we tested triatomine vectors from 23 ... | 2016 | 27106934 |
| comparative proteomic analysis of the saliva of the rhodnius prolixus, triatoma lecticularia and panstrongylus herreri triatomines reveals a high interespecific functional biodiversity. | triatomines are hematophagous arthropods that transmit trypanosoma cruzi and trypanosoma rangeli. feeding behavior and pathogen transmission is known to vary between the different species, and this characteristic is directly or indirectly dependent on the bioactive molecules of the saliva that facilitate the vector-host-parasite interaction. here, we identify, characterize and compare the sialoproteomic (from the greek sialo: saliva) repertoire of important species of the main triatomine genera ... | 2016 | 26940473 |
| the biology of the triatomine bugs native to south central texas and assessment of the risk they pose for autochthonous chagas disease exposure. | triatomine bugs are a group of hematophagous arthropods that can serve as biological vectors for trypanosoma cruzi , the etiological agent of american trypanosomiasis (chagas disease). because of differences in the biology and feeding habits among triatomine species, some are more likely than others to be involved in zoonotic and/or human-to-human transmission cycles of t. cruzi . in an attempt to assess the risk for chagas disease exposure in south-central texas, human habitations across texas ... | 2015 | 26168214 |
| development of data for the identification and characterization of proteins found in rhodnius prolixus, triatoma lecticularia and panstrongylus herreri. | the data presented here were obtained from the saliva of three triatominae, rhodnius prolixus, triatoma lecticularia and panstrongylus herreri from montandon et al. study, doi:10.1016/j.ibmb.2016.02.009 [3]. these data were obtained from spectra generated by the mass spectrometry of proteins observed through the analysis of 2-d electrophoretic profiles. the data were analyzed according to the uniprot code, protein name, protein group, isoelectric point and molecular weight, electrophoretic profi ... | 2016 | 27077085 |
| bionomics and spatial distribution of triatomine vectors of trypanosoma cruzi in texas and other southern states, usa. | defining spatial and temporal occurrences of triatomine vectors of trypanosoma cruzi, the agent of chagas disease, in the us is critical for public health protection. through a citizen science program and field collections from 2012 to 2016, we collected 3,215 triatomines, mainly from texas. using morphological and molecular approaches, we identified seven triatoma species and report sex, length, and blood engorgement status. many citizen-collected triatomines (92.9%) were encountered indoors, i ... | 2018 | 29141765 |
| biology of the introduced species triatoma lecticularia (hemiptera: reduviidae) to northwestern mexico, under laboratory conditions. | the first record of triatoma lecticularia out of its reported distribution area together with the brief description of the said area is provided in this paper. in addition, some biological parameters related to hatching of eggs, life cycle and feeding and defecation behaviors for each instar of one population of t. lecticularia from its previously reported distribution area (pr) and for each instar of that introduced recently found population (is) of this species were evaluated and compared. twe ... | 2018 | 29042261 |
