State) was assessed by monthly samplings. Twenty-four species were identified from a total of 1,185 specimens (74.7% as adults and 25.3% as immatures), with Aedes fluviatilis Lutz as the most frequent species. Several species are new records, and some of them are of public health interest. It is suggested that local environmental changes may alter the relationship between humans and vector mosquitoes.
Fauna Culicidae (Diptera) em depressões de Rochas da margem de um Ribeirão no Norte do Paraná
Depressions in rocks can retain water and become microhabitats that offer ecological conditions as mosquito habitats. Some species of Culicidae use rock holes habitats for laying eggs and the development of its immature stages. The aim of this study was to survey the species of Culicidae that colonize rock holes on the margins of a stream in the north of Paraná State. The study area was located in Sapopema, PR, on the left bank of the stream Lageado Liso. Ten collection points were selected, at which the ecological aspects of the rock pools were analyzed. The collections were performed monthly from November 2000 until October 2001. A total of 4,574 immature mosquitoes were collected. Aedes fluviatilis represented 72.34%, Culex Group Coronator 16.51%, Culex mollis 5.10%, Anopheles argyritarsis 2.65%, Lutzia bigoti 1.84% and Culex eduardoi 1.57% of the total collected. The highest abundances of mosquito species were observed in the summer. The conditions of direct sunlight expose, and the presence of aquatic or semi-aquatic vegetation, were determinant factors for the colonization of this microhabitat.

The damming of Paraná River for the construction of Porto Primavera Hydroelectric Power Plant, between the states of Mato Grosso do Sul, Midwestern Brazil and São Paulo, Southeastern Brazil, has changed the ecological relationships in the area. The objective of the study was to describe the fauna that can be potential vectors in this reservoir, 2 km away from its right bank, in Bataguassu, Mato Grosso do Sul, before flooding. Mosquitoes were monthly captured in different environments from July 1997 to November 1999. During this period 16,553 adult specimens and 1,795 immature forms were collected with richness of 86 different species of adults and 44 different species of immature forms. The fauna presented a richness that included species of epidemiological importance, as Anopheles darlingi and other mosquitoes with potential for arbovirus transmission.

Fragmentos de mata na área urbana ou periurbana podem ser locais favoráveis a procriação de Culicidae. Esse trabalho teve como objetivo levantar as espécies de culicídeos que utilizam criadouros artificiais, suas coexistência e as flutuações populacionais em uma reserva de mata localizada em Londrina PR. Realizou-se coletas quinzenais de outubro de 1995 a setembro de 1996 em pneus e internódios de bambu armadilha que foram instalados ao nível do solo e outros internódios instalados a 2 m de altura. Coletou-se 12.656 espécimes, pertencentes a cinco gêneros e 11 espécies. As espécies mais abundantes nos criadouros foram Limatus durham Theobald, 1901, Culex eduardoi Casal & Garcia, 1968, Aedes terrens (Walker, 1856), Culex quinquefasciatus Say, 1823 e Aedes albopictus (Skuse, 1894). O maior número de indivíduos foi coletado em pneus, sendo que Limatus durham e Aedes terrens, apresentaram preferência nesse criadouro. A presença de Aedes aegypti (Linnaeus, 1762), Aedes albopictus e Haemagogus leucocelaenus (Dyar & Shannon, 1924) em diferentes coletas indica que esse tipo de ambiente não deve ser ignorado nas ações de controle de vetores, merecendo constante monitoramento. Forest fragments in an urban area were found to be a situable site for Culicidae breeding. This research aims to inventory the Culicidae species that use artificial breeding sites, their coexistence, and the population variation in a fragment forest in the Londrina City, Paraná State. Biweekly collecting efforts were performed from October 1995 to September 1996 using tires and bamboo internodes traps installed at a ground level and bamboo internodes traps at two 2 m height. A total of 12,656 culicid specimens belonging to five genus and 11 species were collected. The most abundant species in those artificial breeding sites were Limatus durhami Theobald, 1901, Culex eduardoi Couple & Garcia, 1968, Aedes terrens (Walker, 1856), Culex quinquefasciatus Say, 1823 and Aedes albopictus. (Skuse, 1894). The greatest number of individuals was collect in tires and Limatus durhami and Aedes terrens, showed a preference to the breeding sites. The capture of Aedes aegypti (Linnaeus, 1762), Aedes albopictus and Haemagogus leucocelaenus (Dyar & Shannon, 1924) in different collections efforts indicates that this kind of environment must be taken in account in the vector control actions and constantly monitored.

to 20:00 hr using Shannon traps and human-bait along the lake margin which forms the Itaipu Hydroelectric reservoir, State of Paraná, Brazil. Species prevalence was studied at 15 min intervals. Anopheles albitarsis sensu latu and An. galvaoi, were the most frequently collected mosquitoes. All Anopheles species populations peaked between 18:45 and 19:30 hr. The observations illustrate the existence of a haematophagic activity cycle during the early evening hours: exogenous stimulus (the beginning of sunset) → Shannon trap (light attraction) → human bait (haematophagy) → rest and digestion → exogenous stimulus → Shannon trap or surrounding vegetation. The greater abundance of An. albitarsis collected in human-bait and Shannon trap suggests it may be a potential malaria vector in the region.
Culicidae (Diptera) No Brasil: Relações Entre Diversidade, Distribuição e Enfermidades
Oecologia Australis, 2012
A grande diversidade biológica e o alto endemismo de espécies nomeiam o Brasil como um país megadiverso, contendo cerca de um décimo da biota mundial. Essa riqueza está distribuída no território nacional em seis Biomas continentais: Amazônia, Caatinga, Mata Atlântica, Cerrado, Pantanal e Pampa, os quais são caracterizados pela uniformidade do ambiente, de acordo com o clima, a fitofisionomia, o solo e a altitude. Em uma das grandes ordens de insetos, Diptera, o conhecimento ecológico e taxonômico é focalizado em espécies de importância econômica ou médica, como, por exemplo, em Culicidae. São aproximadamente 470 espécies de Culicidae distribuídas no Brasil, com espécies consideradas como silvestres e outras antrópicas, com maior adaptabilidade a sistemas modificados pelo homem. Um fator que determina a ocorrência dessas espécies é a heterogeneidade estrutural do Bioma, sendo que a maior diversificação de recursos no habitat permite a coexistência. Porém, a tendência dos habitats em se tornarem menores e mais isolados vem causando a perda de diversidade, sendo que no Brasil, as estimativas mais conservadoras indicam que 30% do território natural está alterado por uso humano. A capacidade de adaptação dos Culicidae ao meio antrópico é a razão pela qual essa família tem um grande sucesso evolutivo, permitindo a esses insetos vetores viver em meio a ambientes antropizados. É possível que as enfermidades veiculadas por esses insetos venham a apresentar contínuas adaptações, portanto procura-se destacar a distribuição de Culicidae no Brasil e relacionaá-las a mudanças nos ambientes naturais e na epidemiologia de algumas enfermidades. Deve-se, portanto, assumir políticas de vigilância epidemiológica e entomológica, também relacionando os Culicidae silvestres, em prol de um retrato lúcido da fauna de Culicidae, como um todo, em escala local e global.

The great biological diversity and the high endemism of species nominate Brazil as a megadiverse country, containing about one tenth of the world's biota. This richness is distributed in the country in six continental Biomes: Amazon, Caatinga, Atlantic Forest, Cerrado, Pantanal and Pampa, which are characterized by the uniformity of the environment, according to climate, vegetation type, soil and altitude. In one of the major insect orders, Diptera, the taxonomic and ecological knowledge is focused on species of economic or medical importance, for example, in Culicidae. There are approximately 470 species of Culicidae distributed in Brazil, with species considered wild and others anthropogenic, with greater adaptability to human-modified systems. One factor that determines the occurrence of these species is the structural heterogeneity of the Biome, being that the greatest diversification of resources in the habitat allows the coexistence. However, the trend of the habitats becoming smaller and more isolated has been causing biodiversity loss, that in Brazil, the most conservative estimates indicate that 30% of the natural territory is changed by human use. The Culicidae adaptability to the anthropic environment is the reason why this family has a great evolutionary success, allowing these insects to live in the middle of anthropized environments. It is possible that the diseases spread GUEDES, M. L. P.

Introduction: Entomological surveillance has proven to be an important strategy for monitoring culicidae fauna, aimed at predicting the risk of exposure to pathogen vector species. The present work reports species identified for the first time in the State Rio Grande do Sul and discusses the epidemiological potential displayed by mosquito species occurring in Maquine municipality and in other regions of the State. Methods: Mosquitoes were collected with Nasci vacuum and CDC light traps between December 2006 and December 2008, in the wild, rural and urban areas of Maquine. Results: Fifty-five species were verified, of which 22 were registered for the first time in the state and 10 are potential vector species for the Saint Louis, Oropouche, Aura, Trocara, Ilheus, Rocio, Una, West Nile, and eastern equine encephalitis viruses. Conclusions: These data demonstrate the importance of entomological surveillance as a tool for gathering information and promoting Health Surveillance actions.
