Maruins (Ceratopogonidae: Diptera) do estuário do Rio Pará e do litoral do Estado do Pará, Brasil

The present study surveyed the species of hematophagus biting midges in coastal areas of Para State, Brazil. Two collecting sites were chosen, one a beach on the coast (Praia de Crispim, near Marapanim) and another in the Para River estuary (Outeiro Island, near Belem). Collections were made monthly in 2003, from April to October in Outeiro and the months of June, July, September, and October in Marapanim. Human bait and CDC traps were used. In total 4003 specimens were collected: 18 species of Culicoides Latreille and one of Leptoconops Skuse. L. brasiliensis (Lutz) was the only species common to both sites. The two most abundant species in Outeiro were C. batesi Wirth & Blanton and C. denisae Clastrier, while in Marapanim these were C. maruim Lutz and C. phlebotomus (Williston).

Fauna anofélica da cidade de Belém, Pará, Brasil: dados atuais e retrospectivos

We present the results of anopheline captures in Belem, Para, Brazil, from 1995-2004, and a comparison with captures from 1930-1999. In the earlier period, 20 species were identified: Anopheles albitarsis s.l., An. aquasalis, An. argyritarsis, An. braziliensis, An. darlingi, An. eiseni, An. evansae, An. galvaoi, An. intermedius, An. kompi, An. mediopunctatus, An. nimbus, An. nuneztovari, An. oswaldoi, An. peryassui, An. punctimacula, An. shannoni, An. strodei, An. thomasi, and An. triannulatus. Seven of these species were not found in 1995-2004 (An. argyritarsis, An. eiseni, An. galvaoi, An. kompi, An. nimbus, An. punctimacula, and An. thomasi). The persistence of so many species is probably due to the local preservation of forest areas. Two species are of vectorial importance (An. darlingi and An. aquasalis). An. aquasalis is still the most abundant species (46.26% of adults, 99.21% of larvae) and the only one detected in all capture sites. There is thus a potential risk of malaria transmission in the entire municipality of Belem.

Phlebotomine sand flies (Diptera: Psychodidae) in forest fragments of Belém metropolitan area, Pará State, Brazil, with considerations on vectors of American cutaneous leishmaniasis agents

In order to identify vectors of American cutaneous leishmaniasis (ACL) agents in urban forest fragments of Belem metropolitan area, Para State, Brazil, an entomological study was conducted between 2009 and 2011 in seven ecologically isolated areas using CDC light traps. A total of 1,119 phlebotomine sand flies were collected and out of 22 species identified, six presented epidemiological importance due to their proven and/or putative implications in the transmission of ACL agents in the Brazilian Amazon. These results reveal the need of entomological surveillance in such areas.

Tabanidae (Diptera) of Amazônia XX: description of Tabanus pseudonebulosus n.sp.

Tabanus pseudonebulosus, new species, is described based on 217 female specimens and 5 males collected in Venezuela (Guarico, Aguaio, Santa Elena, and Palmarito) and in Brazil (Parcí: Santana do Araguaia, Serra das Andorinhas in São Geraldo do Araguaia, Serra Norte Carajás and Gorotire; Amazonas: Canutama; Mato Grosso do Sul: Corumbá), mostly in open vegetation, scrub forest and in rocky environments. Observed intraspecific variation in the specimens is presented and related to collection localities, and morphological differences are diagnosed in relation to the similar species Tabanus nebulosus DeGeer 1776 and T. importunus Wiedemann 1828. Morphometrical data and indices for specimens in different localities are provided. Drawings and photo of the new species are presented.

Maruins (Diptera: Ceratopogonidae: Culicoides), após a estação chuvosa, na Reserva de Desenvolvimento Sustentável Itatupã-Baquiá, Gurupá, Pará, Brasil

Los individuos adultos de ambos sexos pueden visitar flores en busca de sustancias azucaradas, pero las hembras usualmente, buscan una alimentación rica en proteína animal para la maduración de sus huevos. Algunas especies son predadoras de invertebrados menores que ellas, principalmente de otros insectos, y otras son ectoparásitos de insectos mayores, tales como mariposas y libélulas; las especies de Culicoides Latreille, las del subgénero Lasiohelea Kieffer, de Forcipomyia Meigen y las de Leptoconops Skuse son ectoparásitos de vertebrados y 7 chupan sangre, principalmente, de aves y mamíferos .

Dichelacera (Dichelacera) corumbaensis n. sp. (Diptera: Tabnidae) from the state of Mato Grosso do Sul, Brazil

Dichelacera (Dichelacera) corumbaensis n. sp. is described from two female specimens collected in the urban area of Corumba city, state of Mato Grosso do Sul. This is one of the six species of Dichelacera occuring in the state and the twenty-eighth species of the subgenus known from Brazil. The head in lateral view, frons, antenna, palpi and wings are illustrated. A differential diagnosis is given related to D. rubricosa, D. unifasciata, D. albifasciata and d. fuscipes.

Description of immatures and association with adults of three species of Anacroneuria Klapálek (Plecoptera: Perlidae) of the Brazilian Amazon.

Nymphs of three species of the genus Anacroneuria Klapálek, 1909, A. marlieri Froehlich, 2001; A. minuta Klapálek, 1922, and A. manauensis Ribeiro-Ferreira, 2001 are described. The associations of nymphs with adults were made by rearing. The known geographical distribution in Brazil of these three species was expanded.

Isolated bacteria from hematophagous Culicidae (Diptera: Nematocera) in Belém, Pará State, Brazil

Bacteria are largely distributed in nature, especially when carried by a vector. They comprise large portions of the human and animal microbiota, and some cause diseases. The diptera of the family Culicidae are directly involved in the vectoring of epidemics of great interest for public health. However, the association between bacteria and Culicidae has been scarcely studied. In order to deepen the knowledge on this subject, we isolated and identified bacteria which have been transported in hematophagous Culicidae in the City of Belém, Pará State. The collection of 296 mosquitoes was carried out using a CDC light trap in eight collection localities, which presented different environmental characteristics within the metropolitan area of Belém. Some were identified to the species level (9) and others to the subgenus (4). It was possible to identify 17 species of bacteria; seven bacteria could only be identified up to their genus. Culex quinquefasciatus and Anopheles aquasalis were the most frequent Culicidae. The most frequent species of bacteria found in the samples were Gemella haemolysans and Enterobacter cloacae. The collection localities in the Terra-Firme and Curió-Utinga districts presented the largest diversity of species of Culicidae.Bacteria are largely distributed in nature, especially when carried by a vector.
