| attraction of chagas disease vectors (triatominae) to artificial light sources in the canopy of primary amazon rainforest. | adult triatomines occasionally fly into artificially lit premises in amazonia. this can result in trypanosoma cruzi transmission to humans either by direct contact or via foodstuff contamination, but the frequency of such behaviour has not been quantified. to address this issue, a light-trap was set 45 m above ground in primary rainforest near manaus, state of amazonas, brazil and operated monthly for three consecutive nights over the course of one year (432 trap-hours). the most commonly caught ... | 2010 | 21225207 |
| presence of intradomicile colonies of the triatomine bug panstrongylus rufotuberculatus in muñecas, la paz, bolivia. | chagas disease is a tropical parasitic disease endemic to latin america which affects more than 10 million people, and kills more than 15,000 people each year. this condition, caused by the protozoan parasite trypanosoma cruzi, is principally transmitted by kissing bugs (triatominae). in bolivia, recent reports by the departmental health service showed the presence of panstrongylus rufotuberculatus in dwellings located in the charazani valley (la paz). a study was then carried out in the area to ... | 2010 | 20955680 |
| stridulatory sound emission of panstrongylus rufotuberculatus champion, 1899, (hemiptera: reduviidae: triatominae). | this study contains the first report of stridulatory sound observed in panstrongylus rufotuberculatus champion, 1899, and also a new record of this species in venezuela. the conditions in which stridulation occurred are described, as well as the general environmental characteristics of the localities where it was found. this triatomine only performs the sound in conditions of extreme provocation. | 2006 | 16862298 |
| high household infestation rates by synanthropic vectors of chagas disease in southern ecuador. | entomological surveys were conducted in five rural communities (138 domiciliary units [dus]) in the southern andes of ecuador. adobe walls and ceramic tile roofs were predominant construction materials. a 35% house infestation rate with panstrongylus chinai (del ponte, 1929) (0.7%), panstrongylus rufotuberculatus (champion, 1899) (0.7%), rhodnius ecuadoriensis (lent & león, 1958) (27%), and/or triatoma carrioni (larrousse, 1926) (7%) was found. adults and nymphs of r. ecuadoriensis and t. carrio ... | 2005 | 15691011 |
| development cycle of panstrongylus rufotuberculatus (hemiptera: reduviidae) under laboratory conditions. | determinant aspects of the development cycle of panstrongylus rufotuberculatus (champion, 1899) were evaluated under laboratory conditions. fertility, duration of life cycle, mortality rate, feeding time, defecation time, thermal reaction time to food source, and volume of blood ingested were studied. from an initial cohort of fifth instars, nine adult pairs were formed, the females of which oviposited 2,338 eggs over 231 d. the eclosion rate was 84.4%; female and male progeny lived 223.56 (14.4 ... | 2004 | 15605638 |
| domiciliation trend of panstrongylus rufotuberculatus in colombia. | the present paper presents evidence of the domiciliation of panstrongylus rufotuberculatus in la gardenia, colombia through the collection of 2 unhatched eggs, 81 nymphs and 10 adults (4 males and 6 females), from 2 rural houses. the transmission risk indicators of trypanosoma cruzi by p. rufotuberculatus in la gardenia, were: domiciliary infestation 7.5%, density 2.35, colonization 66.6%, overcrowding 31.33, natural infection 4.6%, and relative infection 2.5%. these results and findings in peru ... | 2002 | 12048554 |
| presence of panstrongylus rufotuberculatus (champion, 1899) (hemiptera: reduviidae: triatominae) in argentina. | panstrongylus rufotuberculatus is reported for the first time in argentina. four adults were attracted by the light of human dwellings in calilegua national park, jujuy, at 1150 masl within the subtropical humid forest. the individuals were similar to those described in the literature. the epidemiological significance of this species is very low in the area, although deforestation might increase its role in the transmission of trypanosoma cruzi. | 1999 | 10348976 |
| morphometrics of domestic panstrongylus rufotuberculatus in bolivia. | the trend to domesticity in triatominae may represent a transitionary phase, towards increasing vectorial importance in the transmission of chagas disease to humans, and requires sustained entomological surveillance. although generally considered a sylvatic species, panstrongylus rufotuberculatus has been recently captured inside human dwellings in the provinces of nor yungas and muñecas in the department of la paz, bolivia, providing evidence of this species' ability to colonise domestic habita ... | 1998 | 9625919 |
| chagas' disease: an emergent urban zoonosis. the caracas valley (venezuela) as an epidemiological model. | the unprecedented emergence of important public health and veterinary zoonoses is usually a result of exponential population growth and globalization of human activities. i characterized chagas' disease as an emergent zoonosis in the caracas valley (venezuela) due to the following findings: the presence of reservoirs (didelphis marsupialis, rattus rattus) and vectors (panstrongylus geniculatus, panstrongylus rufotuberculatus) infected with trypanosoma cruzi in urbanized or marginalized areas; th ... | 2014 | 25520950 |
| [intra-domiciliary capture of panstrongylus rufotuberculatus (champion, 1899) (hemiptera, reduviidae, triatominae) in piura, peru]. | panstrongylus rufotuberculatus is widely distributed in central and south america. in peru, it has been found in tumbes, piura, and cuzco. the authors report the presence of p. rufotuberculatus in chirinos-la pareja, suyo district, ayabaca province, piura region, peru. twenty-eight specimens were collected in two of 15 dwellings: three 2nd instar, four 3rd instar, two 4th instar, and eight 5th instar nymphs, three male and eight female, in an intra-domiciliary colony of guinea pigs (cavia porcel ... | 2007 | 17700958 |

| distribution of triatomine species in domestic and peridomestic environments in central coastal ecuador. | although the central coast of the ecuador is considered endemic for chagas disease, few studies have focused on determining the risk of transmission in this region. in this study we describe the triatomine household infestation in manabí province (central coast region), determine the rate of trypanosoma cruzi infection and study the risk factors associated with infestation by rhodnius ecuadoriensis. | 2017 | 28968383 |
| on triatomines, cockroaches and haemolymphagy under laboratory conditions: new discoveries. | for a long time, haematophagy was considered an obligate condition for triatomines (hemiptera: reduviidae) to complete their life cycle. today, the ability to use haemolymphagy is suggested to represent an important survival strategy for some species, especially those in genus belminus. as eratyrus mucronatus and triatoma boliviana are found with cockroaches in the blaberinae subfamily in bolivia, their developmental cycle from egg to adult under a "cockroach diet" was studied. the results sugge ... | 2016 | 27706376 |
