Simuliidae (Diptera, Culicomorpha) no Brasil - XII sobre o gênero Thyrsopelma E...

É acrescentado um novo caráter pupal para a espécie T. hirtipupa (Lutz,1910). É evidenciada a existência de dentes no cibário da fêmea de T. guianense (Wise,1911), principal espécie envolvida na transmissão da filaria Onchocerca volvulus (Leuckart,1893) no foco da região amazônica. É proposta uma nova relação para os artículos antenais da larva de T. guianense. É descrita uma nova espécie para o gênero Thyrsope...

Algumas considerações sobre Simuliidae (Diptera : Nematocera)

Com base em observações do abdome pupal de algumas espécies neotropicais de Simuliini e Prosimuliini, sem o uso do KOH (Hidróxido de Potássio) como agente "limpador-clarificante", são propostas algumas alterações nas definições apresentadas por Crosskey (1969) e por Wygodzinsky & Coscarón (1973) para estas tribosSimuliini com áreas membranosas estriadas longitudinais medianas nos esternitos V, VI-VII e algumas ...

Prevalence of Mansonella ozzardi among riverine communities in the municipality...

Introduction: Estimate the prevalence of Mansonella ozzardi infection and calculate the parasitic infection rate (PIR) in simuliid black flies in the municipality of Lábrea, State of Amazonas, Brazil. Methods: Prevalence was measured using the thick blood smear method collected from the fingers and was related to age, sex and occupation. Simuliidae were collected with a suction apparatus, then stained with hema...

Anticoagulant activity in salivary gland homogenates of Thyrsopelma guianense (...

In this study, anticoagulant activity was detected in salivary gland homogenates (SGHs) of Thyrsopelma guianense (Diptera: Simuliidae). The SGH yielded 1.07 μg ± 0.03 (n = 15) of total soluble protein per pair of glands. In addition, following SDS-PAGE (12.5% gel) and silver nitrate staining, 12 polypeptides with molecular weights ranging from 14-69 kDa were detected in all physiological ages analyzed (12 h, 24...

The black flies (Diptera: Simuliidae) from Santa Catarina, Brazil

The Simuliidae fauna from the Santa Catarina state, Brazil, was documented, based primarily on specimens deposited in the collections of the Instituto Oswaldo Cruz, Brazil and the La Plata Museum, Argentina. The results of our survey are organized by mesoregion and by municipality. Of the 51 municipalities where black flies were recorded, 46 represented new unpublished locality records. A total of 29 species be...

A cladistic analysis of Inaequalium (Coscarón & Wygodzinsky, 1984), with inform...

The black flies of the genus Inaequalium present a Neotropical distribution, with Panama at the northern limit, and the Argentinian pampas at the southern, but do not occur in the Central Amazon. This study offers a cladistic analysis establishing a hypothesis of relationships between the species of Inaequalium. A total of 37 characters have been considered in order to establish the hypothetic phylogenetic rela...

A new species of the Culicoides (Hoffmania) hylas species group, Culicoides baniwa Felippe-Bauer is described and illustrated based on a female specimen from the state of Amazonas, Brazil. A systematic key, wing photographs, diagramme of the legs pattern, table with numerical characters of females and a synopsis of the 11 species of the C. hylas group are presented. This paper further presents a new record of C...
