Triatomines know no boundaries: Triatoma delpontei Romaña & Abalos, 1947 (Heteroptera: Reduviidae) discovered in Mato Grosso do Sul State, Brazil.

Triatominae are recognized as vectors of Trypanosoma cruzi, a protozoan which is the etiological agent of Chagas disease. A specimen of Triatoma delpontei was found at Porto Murtinho in Mato Grosso do Sul State, Brazil. This is the first report of the occurrence of T.

Molecular detection of Leishmania and blood meal analysis in sand flies from Corumbá, Mato Grosso do Sul, Brazil.

In this study, we investigated the presence of Leishmania in sand flies collected from a peridomestic area in Corumbá, Mato Grosso do Sul, after an autochthonous case of cutaneous leishmaniasis was confirmed. A total of 1,542 sand flies belonging to seven species were collected, with Lu. cruzi being the most prevalent (94.

Geographic distribution of human leishmaniasis and phlebotomine sand flies in the State of Mato Grosso do Sul, Brazil.

Background: In the State of Mato Grosso do Sul, Brazil, sand flies and cases of visceral (VL) and cutaneous (CL) leishmaniases have been reported in almost all municipalities. The aim of this study was to analyze the geographic distribution of VL and CL in relation the sand fly species found in the municipalities of Mato Grosso do Sul.

Methods: We analyzed VL and CL cases from 2001 to 2018 using data from the Notifiable Diseases Information System (SINAN).

Phlebotomine (Diptera: Psychodidae) fauna in a cavern containing cave paintings and its surrounding environment, Central-West Brazil.

The interior of caves usually presents climate, light, soil, flora and fauna that distinguish it from the external environment. Among the sandfly species found in caves, several may act as vectors of Leishmania spp. and others are a nuisance to humans due to their painful bites.

High molecular prevalence of Leishmania in phlebotomine sand flies fed on chicken blood in Brazil.

Leishmaniases are endemic in Brazil, where Leishmania infantum has been detected in humans, dogs, cats, and phlebotomine vectors. Monitoring synanthropic vector populations is critical for leishmaniasis control-surveillance in such transmission-prone areas. Here, a suite of molecular approaches were used to assess Leishmania infection prevalence and to identify blood-meal sources in a large sample of sand flies collected in anthropic environments of a Leishmania-transmission area in Mato Grosso do Sul State (Rio Verde de Mato Grosso municipality), Central-West Brazil.

Description of Evandromyia (Aldamyia) orcyi, a new phlebotomine species (Diptera: Psychodidae: Phlebotominae) from the State of Mato Grosso do Sul, Brazil.

Background: The genus Evandromyia is widely found in Brazil, but occurs mainly in Brazilian savannah. To date 13 species have been described in the subgenus Aldamyia. Here we described a new species of Evandromyia (Aldamyia) collected in the State of Mato Grosso do Sul, Brazil.

[Occurrence of Panstrongylus guentheri Berg (Hemiptera: Reduviidae) in Mato Grosso do Sul State, Brazil].

The first occurrence of Panstrongylus guentheri Berg in Brazil is presented. This species had been reported only in the territories of Argentina, Paraguay, Bolivia and Uruguay. We have extended the geographic distribution of this Triatominae, with two specimens captured in Bodoquena and Itaporã cities, both in Mato Grosso do Sul State, Brazil.

[Spatial distribution of Aedes albopictus in the southern area of Mato Grosso do Sul State, Brazil].

Objective: To investigate the spatial distribution of Aedes albopictus population to provide input for developing sampling plans and supporting decision making on the control of this vector in field sampling.

Methods: A study was carried out in an urban area that has a vestige of primary vegetation, 20 km away from Dourados, Midwestern Brazil. Ten samplings were conducted between January 28, 2003 and April 9, 2003, using ovitraps which were monitored once a week, and distributed in a fixed sample area with 10 collection points for each sampling 300 m away from each other.
