| The predator-prey relationship of Palaemonetes argentinus Nobili, 1901 and Culex pipiens s.l. larvae was studied under laboratory conditions. The prawns were separated in two groups, isolated and grouped ones. Mosquitoe larvae were offered to prawns in two forms, limited and unlimited offer to both groups. In the first analysis, values of predation did not differ significantly between males and females of P. argentinus. Predation in 24 h was 14,9 ± 4,2 larvae/prawn. A reduction of predation was observed with unlimited offer for the same hour, during all the experiment. Predation with unlimited offer was higher on the first day than on the second, but returned to high values on the third day, for both groups. In the grouped experiment, predation with... |

| A região oeste da Bahia passa por acelerado processo de desenvolvimento agrícola, o que tem gerado problemas de infraestrutura nos municípios. A falta de saneamento básico e de coleta dos resíduos são alguns desses problemas, os quais têm papel importante no aumento de criadouros disponíveis aos culicídeos. Assim, considerando as possibilidades de contato entre vetor e população humana, o objetivo deste trabalho foi estudar a fauna de culicíeos adultos em uma área urbana no oeste da Bahia e verificar a presença de espécies de interesse em saúde pública. As amostragens de mosquitos adultos foram realizadas no município de Barreiras, de fevereiro de 2009 a janeiro de 2010, das 17h30min às 21h00min. Ao total foram capturados 1.744 mosquitos e oito gêneros... |

| Bromeliad-associated mosquitoes (Diptera: Culicidae) in Atlantic Forest in Florianópolis, Santa Catarina, southern Brazil, were studied, examining plants of Vriesea philippocoburgi Wawra and Aechmea lindenii (E. Morren) Baker var. lindenii at secondary Atlantic rain forest, and A. lindenii and Vriesea friburgensis Mez var. paludosa (L. B. Smith) at "restinga" per month, during 12 months. No immature forms of mosquitoes were collected from A. lindenii in the secondary forest. Collections obtained 368 immature mosquitoes, none of them from A. lindenii from rain forest. Culex (Microculex) spp. constituted 79.8% of the total, Wyeomyia (Phoniomyia) spp. 17.93%, and Anopheles (Kerteszia) cruzii (Dyar & Knab, 1908) only 1.36%. The study shows the great... |

| The thermal requeriments of Culex quinquefasciatus (Say, 1823) and the number of generations in the year are determined. The colony to obtain eggs, larvae, pupae and adults was established under laboratory conditions. Every stage was maintained at constant temperature (15, 20, 25 and 30ºC), in cameras, with relative humidity of 80% ± 5 and photophase of 12 hours, to settle down the thermal inferior limit and the thermal constant by the method of the hiperbole. The thermal inferior limit to phase of egg, larvae and pupa were respectively 10.0, 9.1 and 10.2ºC, and 10.2ºC to all the aquatic cycle, with a thermal constant of 207.2 degree-day, with the mean of 15.5 generations per year in Pelotas, State of Rio Grande do Sul. |

| Salinity tolerance is an important trait that governs the ecology of disease‐vector mosquitoes by determining their choice of larval habitat, and consequently their ecological and geographical distribution. Here, we used laboratory strains to determine the osmotic responses of larvae of obligate freshwater disease‐vector mosquitoes (Aedes aegypti, Aedes albopictus, Anopheles coluzzii, An. gambiae, Culex pipiens, and Cx. quinquefasciatus) and assessed their relationship with salinity tolerance. First, we analyzed the acute dose–mortality response of fourth‐instar larvae to salinity; then, we measured their hemolymph osmolality after 24‐h exposure to varying salinities. We found that Ae. albopictus was the most tolerant species, followed by An. coluzzii,... |

| The following species represent first records for Argentina: Culex (Anoedioporpa) canaanensis Lane & Withman, Culex (Anoedioporpa) originator Gordon & Evans, Culex (Culex) declarator Dyar & Knab, Culex (Melanoconion) ribeirensis Forattini & Sallum, Culex (Microculex) neglectus Lutz, Culex (Microculex) pleuristriatus Theobald, Orthopodomyia fascipes (Coquillett) and Wyeomyia (Wyeomyia) medioalbipes Lutz. The species Anopheles (Nyssorhynchus) guarani Shannon and Ochlerotatus (Ochlerotatus) rhyacophilus (Da Costa Lima), recorded for Argentina, were recently resurrected from the synonymy of Anopheles (Nyssorhynchus) lutzii Cruz and Ochlerotatus (Ochlerotatus) scapularis (Rondani). The following species represent the first report... |

| The family and neighbors of a patient infected with W. bancrofti microfilariae were assessed aiming to evaluate the occurrence of cases of lymphatic filariasis in a non-endemic area in the city of Maceió, in the Brazilian state of Alagoas. The patient had previously lived in an endemic focus; however, he has been living in an area where the parasite has never been detected for the past ten years. Female ingurgitated Culex quinquefasciatus mosquitoes captured in the houses of the microfilaremic individual and of his neighbors in the non-endemic region were also examined by polymerase chain reaction (PCR) technique. The thick blood smear examination, blood membrane filtration, and rapid immunochromatography (antigen search) revealed no infected individuals... |
