| wild habitat and related fauna of panstrongylus lutzi (reduviidae, triatominae). | although panstrongylus lutzi (neiva and pinto) is currently the fifth most frequent species of triatominae captured in artificial structures in brazil, its silvatic habitat remains unknown. a survey of its natural ecotopes was performed in an area of bahia state. p. lutzi nymphal instars and adults were detected in burrows of dasypodidae. silvatic habitat of four other endemic triatomine species of the caatinga (triatoma pseudomaculata correa and espinola, triatoma brasiliensis neiva, rhodnius n ... | 2003 | 14765681 |
| risk factors for reinvasion of human dwellings by sylvatic triatomines in northern bahia state, brazil. | the aim of this study in curaça, bahia, northeast brazil was to explore possible factors associated with the infestation of human dwellings by triatoma brasiliensis or triatoma pseudomaculata, two sylvatic triatomine species. we use multiple logistic regression analysis to show how structural features of the peridomiciliary area combine with the number of animals and sociological factors to allow infestation of some dwellings. it is suggested that t. brasiliensis is associated with human activit ... | 2005 | 15868058 |
| peridomestic structure, farming activity and triatomine infestation. | the role of peridomestic structure and farming activity on triatomine infestation was studied on two vector species of chagas disease (triatoma pseudomaculata and t. brasiliensis) in bahia state, northeastern brazil. a randomly selected population issued from 136 farms was divided into four categories according to the householder activity. at regional scale, the dwellings of farmers working on degraded land of irrigated farms are less exposed to t. pseudomaculata infestation. at premises scale, ... | 2006 | 17007216 |
| behavioral plasticity of triatominae related to habitat selection in northeast brazil. | triatoma pseudomaculata corrêa and espínola, 1964 and triatoma juazeirensis costa and felix, 2007 ( = t. brasiliensis neiva, 1911 [part]), are sylvatic vectors of trypanosoma cruzi (chagas, 1909), the causative agent of chagas disease, in northeast brazil-especially in the caatinga region. in an area of caatinga in the state of bahia, we compared the wild and peridomestic habitats of these two species of triatominae to assess their behavioral plasticity in relation to habitat selection in differ ... | 2008 | 18283937 |
| microsatellite markers in triatoma pseudomaculata (hemiptera, reduviidae, triatominae), chagas' disease vector in brazil. | six polymorphic microsatellite loci were isolated and characterized using a microsatellite-enriched genomic library from the chagas' disease vector triatoma pseudomaculata. this species is found in brasil in caatinga areas and predominantly in peridomestic habitats. all the microsatellites tested on a population of t. pseudomaculata sampled in the bahia state, brazil, were polymorphic (2-15 alleles). markers amplification was also tested on six triatoma species and some loci successfully amplifi ... | 2008 | 18571993 |
