Pirahy virus: Identification of a new and potential emerging arbovirus in South Brazil.

Genomic and epidemiological surveillance are paramount for the discovery of new viruses with the potential to cross species barriers. Here, we present a new member of the genus found in and mosquitoes, tentatively named Pirahy virus (PIRAV). PIRAV was isolated from mosquito pools collected in a rural area of Piraí do Sul, South Brazil.

Identification of a novel alphavirus related to the encephalitis complexes circulating in southern Brazil.

In early 2017, an outbreak caused by an unknown and supposedly viral agent in the Marilena region of southern Brazil was investigated. Since the etiological agent causing the outbreak was not identified from human samples, mosquitoes from this region were collected. Three out of 121 mosquito pools collected from the region tested positive for alphavirus in molecular tests.

Systematic notes of Anopheles konderi and its first record in Paraná State, Brazil.

We analyzed nuclear (second internal transcribed spacer and white gene) and mitochondrial (cytochrome c oxidase subunit I) data from Anopheles konderi collected in the Amazonian states of Acre, Amapá, and Rondônia and the southern Brazilian state of Paraná. This was the first record of An. konderi in the state of Paraná.

[Occurrence of Nyssomyia intermedia (Lutz & Neiva) (Diptera: Psychodidae) in Paraná State, south of Brazil].

The occurrence of Nyssomyia intermedia s.lat. in the state of Paraná, Brazil, has been registered by several authors; however, studies have identified this taxon as belonging, in Paraná, to Nyssomyia neivai (Pinto).

[Diversity, distribution and abundance of sandflies (Diptera: Psychodidae) in Parana State, Southern Brazil].

Due to the spread of Visceral leishmaniasis in Brazilian territory, this research was undertaken with the objective to identify the sandfly fauna and aspects of the species behavior in forest and anthropic environments in Paraná State, Brazil. The sandfly captures were sporadically carried out in 37 municipalities of the Paraná state, during the period from March 2004 to November 2005. Each municipality was once visited, when Falcão traps were installed during three consecutive nights in forested fragments and anthropic environments; captures with Shannon traps installed in forests and edge of forests, inspection of walls and electric aspiration in domiciles and forested areas were sporadically undertaken.

[Finding of Haemagogus (Conopostegus) leucocelaenus (Diptera: Culicidae), in the municipality of Porto Alegre, State of Rio Grande do Sul].

In November 2006, an entomological investigation was carried out in a native forest in the municipality of Porto Alegre, State of Rio Grande do Sul. The result was the capture of several Culicidae species, including the first recording of the presence of Haemagogus leucocelaenus in this locality. This species is considered to be a vector for the yellow fever virus in some municipalities of this State, and this was the motivation for the present communication, in order to warn regarding the potential of this area for circulation of the etiological agent for this disease.

[Specificity of the Adultrap for capturing females of Aedes aegypti (Diptera: Culicidae)].

The Adultrap is a new trap built for capturing females of Aedes aegypti. Tests were carried out to evaluate the specificity of this trap in comparison with the technique of aspiration of specimens in artificial shelters. Adultraps were kept for 24 hours inside and outside 120 randomly selected homes in two districts of the city of Foz do Iguaçú, State of Paraná.

[Preliminary information on sandflies in the north of Paraná State, Brazil].

The results from sandfly collections in 10 municipalities in Paraná State, Brazil are reported. The captures were done using Falcão traps in homes, domestic animal shelters and forested areas, from 1999 to 2002. A total of 13,653 sandflies were collected from 10 species of the genera Brumptomyia, Expapillata, Evandromyia, Migonemyia, Pintomyia, Nyssomyia and Psathyromyia.

[Phlebotomine sandflies of Southern Brazil].

Objective: To identify the sandfly fauna and some aspects of their behavior in forest and anthropic environments.

Methods: Sandfly captures were undertaken in farm (23 degrees 6' S; 50 degrees 22' W), in Southern Brazil. Falcão light traps were set in forest, domicile and domestic animal shelters and mosquitoes were collected monthly, between 17h and 7h, from March 1997 to February 1998.
