Culicoides biting midges are small insects that proven vectors of pathogens cause disease in animals and humans. There 1,368 species the world, including 149 Brazil 122 Brazilian Amazon Basin. This study documents specimens were collected between 2013 2015 municipalities Alvorada d'Oeste, Buritis, Cacoal, Costa Marques, Espigão Guajará-Mirim, Pimenta Bueno, Porto Velho São Francisco Guaporé. Collections performed using HP light traps forest, pasture peridomicilie environments.Species newly...
Abstract Culicoides biting midges are medically important haematophagous flies that transmit diseases to animals and humans. This work deals with the basic ecology of populations in northeastern Brazil. Adult midge around urban rural communities were sampled monthly from September 2007 October 2008 light traps. In total, 10,803 representing 17 species collected. The most frequently collected paucienfuscatus (83%), leopoldoi (12%), insignis (2%), paraensis (1%). Trap catches diversity highest...
Culicoides biting midges (Diptera: Ceratopogonidae) are of great medical and veterinary importance because the haematophagous females some species can transmit diseases to humans animals. In order determine presence seasonal abundance bluetongue virus (BTV) vector insignis Lutz at domestic animal sheds in northeastern Brazil, insects were collected once a month between January December 2010. Light traps set from 18.00 06.00 hours pigsty, chicken coop bovine corral. accounted for 81% 22,316...
Abstract Background Almost 1000 cases of American cutaneous leishmaniasis have been registered yearly in Rondônia State, Brazil. Little is known about the Leishmania transmission cycle (vectors and reservoirs) state. This study aimed to evaluate sand fly fauna from two vertical stratification layers order identify potential vectors their blood-meal sources. Methods The was conducted Jamari National Forest. Sand flies were collected canopy (15 m) at ground level (1 using HP light traps during...
Abstract There is very little information available about C ulicoides species ( D iptera: eratopogonidae) in the western B razilian A mazon. However, studies of fauna this region are essential to knowledge and potential vectors within it. Thus, present study aims evaluate abundance, richness composition rural areas state R ondônia, razil. specimens were collected forest pasture environments municipality P orto V elho, using light traps. total 1708 individuals (1136 females 572 males)...
The present paper aims to increase the knowledge on sand fly fauna in cerrado areas of Maranhão state urban, rural and forest environments. research was carried out from October 2007 September 2008, between 18:00h 06:00h, municipality Chapadinha, northeast Maranhão. For insect sampling, CDC light traps were set up peridomicile domicile urban zones as well Cerrado Gallery forests. total 1,401 specimens belonging 17 species sampled, all within genus Lutzomyia. Lutzomyia longipalpis (Lutz &...
This study evaluated the species composition of sand flies and identified potential vectors Leishmania Ross in rural areas Porto Velho, Rondônia State, Brazil. American cutaneous leishmaniasis (ACL) is one gravest threats to public health this state. Sand were collected over course 2014 2015 using HP light traps. Polymerase chain reaction was performed by targeting mkDNA region. In total, 2,344 collected, from which 45 species, nine subgenera, five group identified. The most abundant...
Although malaria is endemic to the Amazon region, little known about susceptibility of potential parasite vectors in Brazil. Assessing vector Anopheles mosquitoes will increase our understanding parasite-vector interactions and aid design control strategies. This study assessed three species midgut infection by Plasmodium vivax, predominant Rondônia State, Blood from P. vivax infected patients was fed aquasalis, darlingi, deaneorum using a membrane feeding assay (MFA). Gametocytemia...
In the rural zone of municipality Chapadinha, Northeastern Maranhão, domestic animal shelters are common and next to dwellings Forest environments widespread cattle raising changes local vegetation, yielding conditions domiciliation process sand flies found in forested environments. The objective this study was know association between area Maranhão state. insects were sampledmonthly from January December 2010, 18:00 06:00, with CDC light traps, set peridomiciliary (corral, chicken roost...
Abstract Culicoides biting midges are small hematophagous flies, some species of which transmit pathogens to livestock and humans. In the Brazilian Amazon Basin, diversity has remained largely unexamined. Jamari National Forest (JNF) is a conservation area in Rondônia State where research environmental education conducted conjunction with protection natural resources, recovery degraded areas. The present study augments our knowledge JNF. survey collected 640 individuals from 41 species; 632...
