Relationship between vertical stratification and feeding habits of mosquito (Diptera: Culicidae) assemblages collected in conservation units in the green belt of the city of São Paulo, Brazil.

São Paulo is one of the largest cities in the world and has several characteristics that favor a diversity of urban and wild mosquitoes. Little is known about how variations in mosquito diversity and feeding preferences for different hosts in different vegetation strata can influence the risk of pathogen transmission to humans. We investigated vertical stratification of mosquitoes and its relationship with vertebrate hosts in environments with different degrees of conservation in two conservation units in the city of São Paulo.

Phenotypic and genetic variation of Triatoma costalimai (Hemiptera: Reduviidae).

Introduction: We aimed to study intraspecific variation in Triatoma costalimai, a potential vector of Chagas disease present in Brazil and Bolivia.

Methods: We analyzed phenotypic (connexivum color patterns, wing morphometrics) and genetic variation (16S mtDNA) of three Brazilian T. costalimai populations.

Morphological study of the urotergite I process in ten species of the genus Triatoma (Hemiptera, Reduviidae, Triatominae).

The insects of subfamily Triatominae exhibit many morphological features used for taxonomic identification. In some species, however, these features are very similar. The authors have proposed by first time the description of the structure referred as urotergite I process.

Occurrences of triatomines (Hemiptera: Reduviidae) and first reports of Panstrongylus geniculatus in urban environments in the city of Sao Paulo, Brazil.

This note reports on occurrences of triatomine species in the city of Sao Paulo, Brazil, registered between 1988 and 2017. Records of triatomines captured in Sao Paulo are based on specimens received spontaneously from Health Surveillance Centers, Health Centers and Zoonosis Control Centers in the city as well as from citizens. Species were identified morphologically at the Public Health Entomology Laboratory, Faculty of Public Health, University of Sao Paulo, where the triatomines, which are vectors of Chagas disease, were tested for Trypanosoma cruzi infection.

Catalog of the entomologic collections of the Faculty of Public Health of the University of Sao Paulo - (2nd series ii): Triatominae (Hemiptera, Reduviidae).

This article reports a list with 912 specimens of the subfamily Triatominae deposited in the Entomological Collection of the Faculty of Public Health of the University of Sao Paulo. The collection is composed of 1 holotype, 3 alotypes, 15 paralectotypes, 77 paratypes, distributed in 5 tribes and 12 genera: Tribus Alberprosenini: genus Alberprosenia Martinez & Carcavallo, 1977; Tribus Bolboderini: genus Microtriatoma Prosen & Martinez, 1952; Tribus Cavernicolini: genus Cavernicola Barber, 1937; Tribus Rhodnini: genus Psammolestes Bergroth, 1941; genus Rhodnius Stal, 1859; Tribus Triatomini: genus Dipetalogaster Usinger 1939; genus Eratyrus Stal 1859; genus Hermanlentia Jurberg & Galvão, 1997; genus Linshcosteus Distant, 1904; 1944; genus Panstrongylus Berg 1879; genus Paratriatoma Barber 1938; genus Triatoma Laporte 1833.

Wing variation in Culex nigripalpus (Diptera: Culicidae) in urban parks.

Background: Culex nigripalpus has a wide geographical distribution and is found in North and South America. Females are considered primary vectors for several arboviruses, including Saint Louis encephalitis virus, Venezuelan equine encephalitis virus and Eastern equine encephalitis virus, as well as a potential vector of West Nile virus. In view of the epidemiological importance of this mosquito and its high abundance, this study sought to investigate wing variation in Cx.

Wing geometry of Triatoma sordida (Hemiptera: Reduviidae) populations from Brazil.

Triatoma sordida has a widespread distribution in Argentina, Bolivia, Brazil, Paraguay, and Uruguay and is frequently found in peridomestic environments. We investigated size and shape variability of T. sordida wings across Brazil.

Description of sp. n. (Hemiptera, Reduviidae, Triatominae) from Pará State, Brazil.

was collected on 12 May 2014 in the Murumurú Environmental Reserve in the city of Marabá, Pará State, Brazil. This study was based on previous consultation of morphological descriptions of 19 species and compared to the identification key for the genus . The examination included specimens from 18 species held in the Brazilian National and International Triatomine Taxonomy Reference Laboratory in the Oswaldo Cruz Institute in Rio de Janeiro, Brazil.
