Large-scale trials of a trapping system designed to collect silvatic Triatominae are reported. Live-baited adhesive traps were tested in various ecosystems and different triatomine habitats (arboreal terrestrial). The always successful, with rate positive generally over 20% reaching 48.4% for palm trees the Amazon basin. Eleven species belonging three genera public health importance (Triatoma, Rhodnius Panstrongylus) captured. This provides an effective way detect presence triatomines...
Triatoma jatai sp. nov. is the first new species of triatomine to be described in state Tocantins, northern region Brazil. It was caught on rock outcrops wild environment and, more recently, invading homes. While T. morphologically similar costalimai, it distinguished by its general colouring, differences blotches connexivum, wing size females and external structures male genitalia. The type series has been deposited Entomological Collection Herman Lent Collection, Oswaldo Cruz...
The conformation of the Sordida subcomplex has been a topic prolonged debate, with diverse methodological approaches employed to discern its constituent species. Up now, Triatoma sordida, T. garciabesi and rosai comprise part this subcomplex. Distinguishing identifying these three species pose significant challenges due their pronounced morphological similarity, overlapping distributions, presence natural hybrids. This study aims uncover genetic diversity geographic spread by analyzing...
Abstract Background Chagas disease (CD) is a neglected zoonosis that requires study through the One Health approach, as it involves various aspects of animal, environmental, and human health in its transmission cycle. This affects 7 million people 20 countries Latin America, resulting approximately seven thousand deaths annually worldwide. Local knowledge crucial for developing educational strategies to mitigate risks transmission, particularly endemic areas. Aims In this study, we present...
The Sordida subcomplex (Triatominae) comprises four species, Triatoma garciabesi, T. guasayana, patagonica and sordida, which differ in epidemiological importance adaptations to human environments. Some morphological similarities among species make taxonomic identification, population differentiation delimitation controversial. garciabesi sordida are the most similar having been considered alternatively two a single until was re-validated, mostly based on morphology of male genitalia. More...
Observations on the ecology of silvatic Triatominae are still fragmentary, principally because target species in control process almost exclusively domestic. Report invading human dwellings must lead research to be focused their original ecology, order assist understanding domestication and devising strategies for surveillance.
Chagas disease is a complex anthropozoonosis with distinct domestic and sylvatic mammal species acting as potential reservoirs. The diversity of vector their habitats are among the factors that hinder control disease. Control programs periodically monitor prevalence T. cruzi infection in insect bugs through microscopical observation diluted feces. However, microscopy presents limited sensitivity samples low parasite numbers, difficulties examining all evolutionary stages may turn be to...
During a medical entomology course in Boa Vista, Roraima, colonies of Triatoma maculata closely associated with pigeon nests were observed concrete air-conditioner box located on the external plastered and cemented walls modern brick-built apartment block. In only one eight-hole ceramic brick, inside box, 127 specimens T. collected. is recognised vector Trypanosoma cruzi surrounding area its domiciliation increases risk Chagas disease transmission.
A temporal observational study on culicid entomofauna was conducted in a region characterized as fragment of the Atlantic Forest that forms Tinguá Biological Reserve State Rio de Janeiro. This investigation performed with aim analyzing influence climatic factors (temperature and relative air humidity) activity levels at different times day among mosquito species within ecosystems form Reserve. The abundance index dominance coefficient were calculated relation to 61 caught four sampling...
The ecology of mosquitoes were studied (Diptera: Culicidae) in areas Serra do Mar State Park, São Paulo, Brazil. Systematized monthly human bait collections made three times a day, for periods 2 or 3 h each, sylvatic and rural 24 consecutive months (January 1991 to December 1992). A total 24, 943 specimens adult belonging 57 species collected during 622 collective periods. Coquillettidia chrysonotum was the most frequent mosquito (45.8%) followed by Aedes serratus (6.8%), Cq. venezuelensis...
Estabelecemos a influência exercida pela cobertura vegetal de quatro diferentes biótopos em áreas do Parque Nacional Iguaçu (PNI) sobre fauna local mosquitos. Realizaram-se capturas bimestrais, isca humana e armadilha Shannon, três períodos dia, ambiente silvestre domiciliar, durante 24 meses consecutivos. Dentre os 20.273 espécimes fêmeas adultas capturadas, pertencentes 44 espécies, Ochlerotatus serratus (10,3%), Haemagogus leucocelaenus (9,7%), Mansonia titillans (9,6%) Chagasia fajardoi...
The mosquito (Diptera: Culicidae) ecology was studied in areas of Serra do Mar State Park, São Paulo, Brazil. Systematized biweekly human bait collections were made three times a day, for periods 2 or 3 h each, sylvatic and rural 24 consecutive months (January 1991 to December 1992). A total 24, 943 adult mosquitoes belonging 57 species collected during 622 collective periods. Aedes scapularis, Coquillettidia chrysonotum, Cq. venezuelensis, Wyeomyia dyari, Wy. longirostris, theobaldi palmata...
Triatoma pseudomaculata Corrêa and Espínola, 1964 juazeirensis Costa Felix, 2007 ( = T. brasiliensis Neiva, 1911 [part]), are sylvatic vectors of Trypanosoma cruzi (Chagas, 1909), the causative agent Chagas disease, in northeast Brazil-especially caatinga region. In an area State Bahia, we compared wild peridomestic habitats these two species Triatominae to assess their behavioral plasticity relation habitat selection different environments. environment, is never shared. found trees bird...
An outbreak of Chagas disease, possibly involving its vector Triatoma brasiliensis brasiliensis, was identified in the state Rio Grande do Norte (RN). Given historical significance this public health, study aimed to evaluate role transmission dynamics protozoan Trypanosoma cruzi an area undergoing desertification Seridó region, RN, Brazil. We captured triatomines sylvatic and anthropic ecotopes. Natural infection determined using parasitological molecular methods we discrete typing units...
The ecology of mosquito species (Diptera: Culicidae) was studied in areas the Serra do Mar State Park, São Paulo, Brazil. influence lunar cycle and daily biting rhythms populations were analyzed. Systematized biweekly human bait collections made a silvatic environment for 24 consecutive months (January 1991 to December 1992). A total 20,591 specimens adult mosquitoes belonging 55 collected from 545 catches. Sabethini captured exclusively during daylight periods, with exception Trichoprosopon...

Triatoma carcavalloi is considered a rare Chagas disease vector often collected inside domiciles in Rio Grande do Sul State. In this Brazilian state, T. has been the same ecotope (rock piles) with two other species (T. rubrovaria and circummaculata), which it also shares morphological characteristics. Previous studies placed complex ("infestans complex") subcomplex ("rubrovaria subcomplex") as rubrovaria, whereas circummaculata was "circummaculata complex." The phylogeny of group composed 16...
