Quintas, Hélder; Coelho, Cláudia A.; Valentim, Ramiro; Vila, Ana Grau; Prendes, Sergio Marques; Maurício, Raimundo; Mendonça, Álvaro

The aim of this work was to study the seroprevalence of paratuberculosis in the Northeast of Portugal in order to discern its economic impact, and to prioritize the allocation of disease control resources. The goat flocks studied were located in the region of Trás-os-Montes e Alto Douro, Northeast of Portugal and included 3 counties (Macedo de Cavaleiros, Mirandela and Alfandega da Fé). In each flock, veterinar...

Lutzomyia longipalpis s.l., the main vector of Leishmania chagasi in Latin America, is a species complex although the exact number of siblings is yet unknown. In Brazil, the siblings differ in male copulatory courtship songs and pheromones that most certainly act as pre-zygotic reproductive barriers. Here we analysed the reproductive isolation between three allopatric and two sympatric populations of Lu. longip...

Lutzomyia intermedia (Lutz & Neiva, 1912) and L. whitmani (Antunes & Coutinho, 1939) (Diptera: Psychodidae: Phlebotominae), two important vectors of American cutaneous leishmaniasis in Brazil, occur in sympatry in the locality of Posse county, Petrópolis municipality, state of Rio de Janeiro, Brazil. We investigated the influence of the lunar cycle on the frequency of specimens of the two species caught...

Lutzomyia intermedia and Lutzomyia whitmani occur sympatrically in the district of Posse, municipality of Petrópolis, in the State of Rio de Janeiro (114 km from the city of Rio de Janeiro), where sand flies were captured weekly for three consecutive years in both the peridomicile and forest, in two first years from 18:00 to 22:00 h, using a Shannon trap and CDC light traps. The anthropophilic habit was assesse...

Souza,Nataly A; Andrade-Coêlho,Claudia A; Vilela,Maurício L; Rangel,Elizabeth F

During two consecutive years, studies on the sand fly fauna in Poço das Antas and Fazenda Bom Retiro, two Atlantic Rain Forest Reserves from the State of Rio de Janeiro, were performed using Shannon traps, CDC light traps and human bait collections. Eleven species were identified; Lutzomyia longipalpis, L. migonei, L. edwardsi, L. intermedia, L. whitmani, L. fischeri, L. shannoni, L. ayrozai, L. hirsuta, L. mon...

Andrade-Coêlho,Cláudia A; Santos-Mallet,Jacenir; Souza,Nataly A; Lins,Ulisses; Meirelles,Maria Nazareth L; Rangel,Elizabeth F

A morphological study of the midgut of Lutzomyia intermedia, the primary vector of cutaneous leishmaniasis, in southeast Brazil, was conducted by light, scanning and transmission electron microscopy. The midgut is formed by a layer of epithelium of columnar cells on a non-cellular basal lamina, under which there is a musculature, which consists of circular and longitudinal muscular fibers. A tracheolar network ...

Azevedo,Alfredo CR; Vilela,Maurício L; Souza,Nataly A; Andrade-Coelho,Claudia A; Barbosa,André F; Firmo,Antônio LS; Rangel,Elizabeth F

The municipality of Ilhéus, State of Bahia, has a focus of cutaneous leishmaniasis where entomological studies were carried out to determine the sand fly species and their habits. Lutzomyia migonei, L. sallesi, L. tupynambai, L. schreiberi, L. intermedia, L. whitmani, L. yuilli yuilli, L. fischeri, L. pessoai, L. shannoni and L. misionensis were identified. Lutzomyia whitmani was the predominant species. Specim...

The influence of sugars and amino acids on the blood-feeding behaviour, oviposi...

Souza,Nataly A.; Andrade-Coelho,Claudia A.; Barbosa,André F.; Vilela,Mauricio L.; Rangel,Elizabeth F.; Deane,Maria P.

Schneider's Drosophila medium, a complex amino acid rich medium was tested alone and with seven different sugars for some aspects of the biology of Lutzomyia longipalpis. Statistically significant results were obtained when sucrose was used alone, indicating that among the sugars tested, this is still the most suitable and practical one for the maintenance of L. longipalpis colonies. However, the addition of Sc...
