Scanning electron microscopy was used to examine and describe the egg of Psorophora ciliata, which was not previous adequately described, and the egg of Ps. ferox, which exhibited regional variation. Eggs of Ps.

New Records of Phlebotomine Sand Flies (Diptera: Psychodidae) From the State of Alagoas, Northeast of Brazil.

Phlebotomine sand flies are small insects of great medical importance. This study presents new records of phlebotomine sand flies, which augment the list of species, recorded in the state of Alagoas, Brazil. Sand flies were collected using CDC miniature light traps.

Emergent and Reemergent Arboviruses in South America and the Caribbean: Why So Many and Why Now?

Varios arbovirus han emergido y/o reemergido en el Nuevo Mundo en las últimas décadas. Los virus Zika y chikungunya, anteriormente restringidos a África y quizás Asia, invadieron el continente, causando gran preocupación; además siguen ocurriendo brotes causados por el virus dengue en casi todos los países, con millones de casos por año. El virus West Nile invadió rápidamente América del Norte, y ya se han encontrado casos en América Central y del Sur.

Contribution to the Biodiversity Assessment of Mosquitoes (Diptera: Culicidae) in the Atlantic Forest in Santa Catarina, Brazil.

The mosquito fauna of a coastal area of Santa Catarina state, Brazil (Baixada do Maciambu), was assessed, and possible mosquito larval habitats were mapped. Five new species records for the state are presented, two of which also are new genera records. From the 24 recognized species present in the area, 28% were from the subfamily Anophelinae and 72% from the Culicinae.

A Rare Case of Labial Myiasis caused by Dermatobia hominis.

The aim of this article is to present a rare case of myiasis caused by Dermatobia hominis. Myiasis is a disease caused by invasion of tissues of animals and humans by larval stages of dipterous (2-winged) flies. There are few reports of oral myiasis in the literature, mostly related to Cochliomyia hominivorax larvae.

Diversity of yellow fever mosquito vectors in the Atlantic Forest of Rio de Janeiro, Brazil.

Introduction: Environmental modifications caused by human activities have led to changes in mosquito vector populations, and sylvatic species have adapted to breeding in urban areas.

Methods: Mosquitoes were collected using ovitraps in three sampling sites in the Atlantic Forest in the State of Rio de Janeiro, Brazil.

Results: We collected 2,162 Culicidae specimens.

Zika virus in Brazil and the danger of infestation by Aedes (Stegomyia) mosquitoes.

Zika virus, already widely distributed in Africa and Asia, was recently reported in two Northeastern Brazilian: State of Bahia and State of Rio Grande do Norte, and one Southeastern: State of São Paulo. This finding adds a potentially noxious virus to a list of several other viruses that are widely transmitted by Aedes (Stegomyia) aegypti and Aedes (Stegomyia) albopictus in Brazil. The pathology and epidemiology, including the distribution and vectors associated with Zika virus, are reviewed.

Genetic structuring and fixed polymorphisms in the gene period among natural populations of Lutzomyia longipalpis in Brazil.

Background: Even one hundred years after being originally identified, aspects of the taxonomy of the sand fly Lutzomyia longipalpis, the principal vector of Leishmania infantum in the Americas, remain unresolved for Brazilian populations of this vector. The diversity of morphological, behavioral, biochemical, and ethological characters, as well as the genetic variability detected by molecular markers are indicative of the presence of a complex of species.

Methods: In this study, a 525 bp fragment of the period gene was used to evaluate sympatric populations of L.

Scanning electron microscopy of eggs of Georgecraigius fluviatilis (Lutz) (Diptera: Culicidae, Aedini).

Scanning Electron Microscopy was used to describe the eggs of Georgecraigius fluviatilis (Lutz). Length is 722.8±39.

Scanning electron microscopy of eggs of Sabethes cyaneus.

Mosquitoes of the Neotropical genus Sabethes, some species of which are yellow fever vectors, most often develop through the immature stages in tree holes. Sabethes eggs have not been previously characterized using scanning electron microscopy. Eggs of Sabethes cyaneus (length: 349.

Bromelicolous Polypedilum Kieffer from South Brazil (Diptera: Chironomidae).

Feeding patterns of Culex quinquefasciatus (Diptera: Culicidae) from eastern Santa Catarina state, Brazil.

Blood-feeding sources of Culex quinquefasciatus Say (Diptera: Culicidae) collected in the eastern region of the Brazilian state of Santa Catarina were analyzed by precipitin technique. One hundred fifty-four female mosquitoes collected by CDC traps in the Navegantes municipality 13-15 February 2005 reacted to one or more of eight antisera, including chicken, dog, goat, sheep, horse, opossum, human and rodent antisera. One hundred thirty-seven specimens (89%) reacted to only one source, and 17 (11%) specimens reacted to two sources.

Analysis of an alternative method for the study of bromeliad-associated fauna in plants with different foliar organization.

The efficiency of an alternative method of collection (by suction of water) for the study of Culicidae and Chironomidae (Diptera), Scirtidae (Coleoptera) and Coenagrionidae (Odonata) in bromeliads with different foliar architecture in a restinga at Florianópolis, SC, Brazil, was studied. The alternative method was less efficient to collect Culicidae and Chironomidae (Wilcoxon test p < 0.05) and was more efficient to Scirtidae and Coenagrionidae (Wilcoxon test p > 0.
