ABSTRACT We assessed the immature stages of Ceratopogonidae (Diptera) in artificial containers in an urban forest fragment in Manaus (Brazil), including their behavioral, biological and ecological information. In addition, we evaluated the effects of deforestation in an open and forested area on Ceratopogonidae communities. Immatures were sampled between August 2012 and July 2014 in artificial containers installed in both habitat types. We collected 685 immatures of seven morpho-species of Bezzia Kieffer, Culicoides Latreille, Dasyhelea Kieffer, Forcipomyia Meigen, and Palpomyia Meigen. In the open area, we recorded higher temperature and electrical conductivity values than in the forested area; however, these variables did not differ between seasons. Water volume was higher in open area and in rainy season, while pH was similar in both areas and seasons. Species richness was higher in forested area, but did not differ between seasons. We did not record differences in abundance between areas or seasons. Community composition differed between areas, but not between seasons. We provide the first records of Culicoides (Hoffmania) insignis Lutz and C. (Haematomyidium) quasiparaensis Clastrier in artificial containers from the state of Amazonas. Our results suggest that the preservation of forested areas in Amazonas is fundamental for the maintenance of the life cycle of some species of Ceratopogonidae.

Resumo A. macrorrhizos (Araceae) é cultivada e se prolifera naturalmente em locais sombreados em diversos fragmentos de mata na zona urbana de Manaus. A planta adulta apresenta axilas que acumulam água da chuva (phytotelmata) e servem de criadouro para diversas famílias de insetos aquáticos. O objetivo do trabalho foi conhecer a composição da entomofauna associada às axilas de A. macrorrhizos, na área urbana de Manaus, Amazonas, Brasil. Entre 2005 e 2007, indivíduos de A. macrorrhizos foram amostrados em cinco fragmentos urbanos de mata, totalizando 184 unidades amostrais. Uma mangueira de sucção manual foi utilizada para coletar a fauna associada. Um total de 1.941 imaturos de Diptera foram coletadas, representadas pelas seguintes famílias: Culicidae (96,5%), Chironomidae (2%), Psychodidae (0,7%), Ephydridae (0,7%) e Corethrellidae (0,1%). Foram identificadas cinco espécies de Culicidae: Wyeomyia melanocephala Dyar & Knab, 1906 (91,7%), Wy. ypsipola Dyar, 1922 (4,3%), Aedes albopictus (Skuse, 1894) (2,3%), Ae. aegypti (Linnaeus, 1762) (1,5%) e Johnbelkinia longipes (Fabricius, 1805) (0,1%). Os representantes de Culicidae foram os mais abundantes confirmando a importância desse grupo nas comunidades associadas a fitotelmatas, com relação positiva com o volume de água por planta (p < 0.05). A ocorrência de Ae. aegypti e Ae. albopictus nas axilas de A. macrorrhizos demonstra o potencial dessa Araceae como criadouro para estas espécies de importância médica. Contudo, a real contribuição dessa Araceae na manutenção e dispersão populacional dessas duas espécies de mosquitos ao longo do ano precisa ser melhor estudada.

Abstract Alocasia macrorrhizos (L.) G.Don grows and proliferates in shaded areas in several forest fragments in urban zones. The adult plant has axils that accumulate rain water (phytotelmata) and serve as breeding sites for several families of aquatic insects. The objective of this study was to determine the composition of the entomofauna associated with water accumulations in axils of A. macrorrhizos in urban areas of Manaus, Brazil. Individuals of A. macrorrhizos were sampled in five forest fragments, between April/2005 and March/2007 in urban areas of Manaus, totaling 184 sampling units. A manual suction hose was used for the removal of entomofauna. A total of 1,941 immatures of Diptera were collected representing the following families: Culicidae (96.5%), Chironomidae (2%), Psychodidae (0.7%), Ephydridae (0.7%) and Corethrellidae (0.1%). Five Culicidae species were identified: Wyeomyia melanocephala Dyar & Knab, 1906 (91.7%), Wy. ypsipola Dyar, 1922 (4.3%), Aedes albopictus (Skuse, 1894) (2.3%), Ae. aegypti (Linnaeus, 1762) (1.5%) and Johnbelkinia longipes (Fabricius, 1805) (0.1%). The members of Culicidae were the most abundant, confirming the importance of this group in communities associated with phytotelmata, with a positive relation to the volume of water (p < 0.05). The occurrence of Ae. aegypti and Ae. albopictus in axils of A. macrorrhizos demonstrates the potential of this Araceae as a breeding site of these medically important species. However, the real contribution of this Araceae in the maintenance and dispersion of populations of these two species of mosquitoes throughout the year should be further studied.

ABSTRACT The fourth instar larva and pupa of Atrichopogon delpontei Cavalieri and Chiossone are described for the first time. The immatures were collected from stream margins in the northern Brazilian states Rondônia and Piauí, and subsequently reared to adults. Larvae and pupae are illustrated and photomicrographed. Details on the rearing process and feeding behavior in laboratory, bionomics and notes on habitats are also provided.

Uma espécie nova da Região Neotropical, Stilobezzia (Stilobezzia) pseudopunctulata Cazorla & Ronderos, é descrita e ilustrada a partir de adultos macho e fêmea e exúvia pupal. Os adultos foram coletados nas províncias argentinas de Chaco, Formosa, Corrientes e Buenos Aires e em Santa Cruz, Bolívia. A pupa foi coletada em tapetes de macrófitas aquáticas flutuantes em um lago na Ilha de Marchantaria, nas proximidades de Manaus, Brasil. Esta espécie nova é comparada com a sua congênere semelhante Stilobezzia punctulata Lane, a partir da qual pode ser distinguida principalmente pela asa com apenas duas manchas escuras, parâmeros mais longos e em forma de gancho, órgão respiratório da pupa com 11-12 poros e processo apicolateral do segmento anal muito curto.

A new species from the Neotropical Region, Stilobezzia (Stilobezzia) pseudopunctulata Cazorla & Ronderos, is described and illustrated based on male and female adults and pupal exuviae. Adults were collected in the Argentinian provinces of Chaco, Formosa, Corrientes and Buenos Aires, and in Santa Cruz, Bolivia. The pupa was collected from mats of floating aquatic macrophytes in a lagoon in Ilha da Marchantería, in the vicinities of Manaus, Brazil. This new species is compared with its similar congener Stilobezzia punctulata Lane, from which it can be mainly distinguished by the wing with only two dark spots, the parameres longer and hook-shaped, the pupal respiratory organ with 11-12 pores and the very short apicolateral processes of the anal segment.

The aim of this work was to investigate the diversity of macroinvertebrates and also verify if the abundance and diversity of Diptera were influenced by the abiotic factors. The samples were collected from the epiphytic and terrestrial bromeliads G. brasiliensis (1 and 3m) in wet and dry seasons at Reserva Adolpho Ducke analyzed total of 144 samples were analyzed from a total of 15,238 individuals collected. These conatined 14,097 insects and, among these, 8,258 were immature Diptera, represented by eight most abundant families: Chironomidae, Ceratopogonidae and Culicidae. The relationship of Diptera diversity was influenced by the seasons and stratifications (p= 0.01); the abundance was influenced by the volume of water (p= 0.02) and the relationship between the season and volume of water in the terrestrial bromeliads was significant (p= 0.01). This study represented the first contribution to knowledge of community of macroinvertebrates associated to bromeliads G. brasiliensis in Central Amazon.

Pupa e adulto macho previamente desconhecidos de Neobezzia fittkaui Wirth & Ratanaworabhan (Diptera, Ceratopogonidae). A pupa de Neobezzia fittkaui Wirth & Ratanaworabhan, 1972 foi coletada em macrófitas aquáticas flutuantes (Salvinia auriculata Aubl., Salviniaceae) na Ilha da Marchantaria próximo a Manaus, Brasil e o adulto macho criado foi descrito, fotografado e ilustrado pela primeira vez. Esta é a primeira descrição para a pupa do gênero Neobezzia Wirth & Ratanaworabhan.

The previously unknown pupa and adult male of Neobezzia fittkaui Wirth & Ratanaworabhan (Diptera, Ceratopogonidae). The pupa of Neobezzia fittkaui Wirth & Ratanaworabhan, 1972, collected from a mat of floating fern (Salvinia auriculata Aubl., Salviniaceae) in Ilha da Marchantaria near Manaus, Brazil and the reared adult male are described, photographed and illustrated for the first time. This is the first detailed pupal description for the genus Neobezzia Wirth & Ratanaworabhan.

Adults of Tabanidae may become serious pests wherever they occur due to their attack to humans and others animals. Tabanids were captured near ground, water surface and at 25 m high on primary forests and forest gaps of anthropogenic origin, to understand their abundance, seasonality, diversity and similarity on such environments. Collections were carried out in the Base II of the War Instruction Center in the Jungle (CIGS) located at 54 km from Manaus municipality, Amazonas state. Two Malaise flight interception traps and four attraction traps (two suspended at 25 m high and two above the water surface of igarapé) were installed in forest gap and primary forest, areas for 10 consecutive days, during 15 months. A total of 2,643 specimens of 66 species were captured. Diachlorini (35 species /11 genera) was the most abundant tribe, followed by Tabanini (19 species /three genera), Chrysopsini (seven species /one genus) and Scionini (five species /two genera). Seventeen species were captured only in the primary forest, 11 in the anthropic clearing, and 38 species were common to both environments. The most abundant species were Phorcotabanus cinereus (Wiedemann), Tabanus occidentalis L, Chrysops laetus Fabricius and Tabanus angustifrons Macquart. The greatest richness was found in drier months (September/October) in both areas. Theforest gap showed higher abundance of specimens (1,827) than the primary forest (816). Traps suspended above the water surface were the most efficient (1,723 specimens) probably due to the dispersion of horseflies over small streams.

Mosquitos da família Culicidae desenvolvem suas formas imaturas em vários ambientes na dependência de circunstâncias diversas. Este trabalho representa a primeira contribuição ao conhecimento ecológico de culicídeos em G. brasiliensis e tem como objetivo inventariar os imaturos em bromélias em dois períodos sazonais, analisando a abundância, riqueza e a influência das variáveis abióticas pH, condutividade e volume de água sobre as populações de Culicidae. Foram realizadas coletas na Reserva Adolpho Ducke, Manaus, Amazonas, Brasil entre 2003 e 2005. Seis coletas foram realizadas no período chuvoso e seis na estação seca. Em cada amostragem, seis bromélias terrestres e seis epífitas foram coletadas, totalizando 144 unidades amostrais. Um total de 444 imaturos foi coletado, distribuídos nas seguintes espécies: Culex (Microculex) stonei Lane & Whitman, Culex (Microculex) chryselatus Dyar & Knab, Culex (Microculex) sp., Wyeomyia (Hystatomyia) autocratica Dyar & Knab e Wyeomyia (Hystatomyia) splendida Bonne-Wepster & Bonne. A relação entre abundância de Culicidae e períodos não foi significativa, entretanto, o período seco apresentou maior representatividade de imaturos. Houve significância na relação do volume de água e abundância (p= 0,003) e riqueza (p= 0,001) de culicídeos. O pH foi o único parâmetro relacionado positivamente com a ocorrência das espécies Wy. autocratica (p= 0,010) e Wy. splendida (p= 0,006) ressaltando a influência deste fator na estruturação das comunidades bromelícolas.

Mosquitoes in the family Culicidae develop their immature forms in different environments depending on various circumstances. This study represents the first contribution to the ecological knowledge of culicids living in the bromeliad G. brasiliensis. The objectives of the study were to compare the Culicidae fauna of bromeliads in two seasonal periods, analyzing their abundance, richness and the influence of pH, conductivity and water volume, on the populations. Sampling was done at Reserva Adolpho Ducke, Manaus, Amazonas, Brazil between 2003 and 2005. Six samplings were done in the rainy season and six in the dry season. On each sampling day, six terrestrial and six epiphytic bromeliads, totaling 144 sampling units, were retrieved. A total of 444 immature mosquitoes were collected, distributed in the following species: Culex (Microculex) stonei Lane & Whitman, Culex (Microculex) chryselatus Dyar & Knab, Culex (Microculex) sp., Wyeomyia (Hystatomyia) autocratica Dyar & Knab and Wyeomyia (Hystatomyia) splendida Bonne-Wepster & Bonne. The relationship between abundance of Culicidae and sampling period was not significant, although abundance was higher in the dry period. There were significant correlations between water volume and the abundance (p = 0.003) and richness (p = 0.001) of culicids. The pH was positively related to the occurrence of the species Wy. autocratica (p= 0.010) and Wy. splendida (p= 0.006), demonstrating the influence of this factor in the structuring of bromeliad-inhabiting communities.

Algumas espécies da família Culicidae são importantes vetores de doenças em humanos e em outros animais. Estágios imaturos são filtradores não seletivos de partículas orgânicas e microrganismos. Estudos da diversidade microbiológica podem contribuir para a descoberta de novas substâncias que podem ser usadas em indústrias farmacêuticas, para alimentação ou para controle biológico. O objetivo deste estudo foi isolar e identificar os fungos associados a larvas de Culicidae encontradas em diferentes tipos de criadouros (natural e artificial), como casca de frutos, buracos em pedras, lagoas, plantas aquáticas, bráctea de palmeira e potes de cerâmica, em vários municípios da Amazônia Brasileira, principalmente no Amazonas e em Rondônia. O total de 38 isolados foram obtidos a partir de larvas de Aedes aegypti (L.), Aedes fluviatilis (Lutz), Trichoprosopon digitatun (Rondani), Anopheles argyritarsis argyritarsis Robineau-Desvoidy, Anopheles darlingi Root, Aedeomyia squamipennis (Lynch Arribálzaga), Mansonia titillans (Walker) e Uranotaenia sp. Os fungos que ocorreram nas larvas de Culicidae foram: Acremonium kiliense, Aspergillus sydowii, Fusarium sacchari var. sacchari, Fusarium merismoides var. merismoides, Gliocladium viride, Paecilomyces sp., Penicillium citrinum, Penicillium sclerotiorum, Penicillium melinii, Penicillium oxalicum. Características macro-microscópicas dos isolados foram apresentadas, assim como informações sobre a distribuição geográfica.

Several species of the family Culicidae are important vectors of diseases in humans and other animals. Immature stages are filter-feeders of organic particulate matter and microorganisms. Studies on microbial diversity can contribute to the discovery of new substances that can be used in the pharmaceutical industry for food or for biological control. The aim of this study was to isolate and identify the fungi associated with Culicidae larvae found in different habitats (natural and artificial), such as fruit shells, rock holes, lakes, aquatic plants, palm bracts and ceramic pots, in several municipalities of Brazilian Amazonia, especially in the states of Amazonas and Rondônia. A total of 38 fungal lineages were isolated from larvae of Aedes aegypti (L.), Aedes fluviatilis (Lutz), Trichoprosopon digitatum (Rondani), Anopheles argyritarsis argyritarsis Robineau-Desvoidy, Anopheles darlingi Root, Aedeomyia squamipennis (Lynch Arribálzaga), Mansonia titillans (Walker) and Uranotaenia sp. The following fungi occurred associated with the larvae of Culicidae: Acremonium kiliense, Aspergillus sydowii, Fusarium sacchari var. sacchari, Fusarium merismoides var. merismoides, Gliocladium viride, Paecilomyces sp., Penicillium citrinum, Penicillium sclerotiorum, Penicillium melinii and Penicillium oxalicum. Macro- and microscopic characteristics of the lineages are presented, as well as information on their geographical distribution.

A larva de último estádio de Bromeliagrion rehni Garrison in De Marmels & Garrison, 2005 é descrita e ilustrada e informações bionômicas sobre seu hábitat são apresentadas. O estudo foi conduzido na Reserva Florestal Adolpho Ducke, localizada em Manaus, Amazonas, Brasil. Entre abril de 2003 e abril de 2005, foram realizadas 12 amostragens, seis no período chuvoso e seis no seco. Para cada amostragem, 12 bromélias de Guzmania brasiliensis Ule, 1907 (Bromeliaceae) foram analisadas, seis terrestres e seis epífitas, totalizando 144 amostras. Um total de 75 espécimes de B. rehni foi coletado. A relação entre a abundância das larvas e os parâmetros ambientais mensurados (volume (ml), pH, estação e estratificação) foi significativa (ANCOVA, F = 5,296, df = 130, p < 0,001). Larvas foram mais abundantes na estação chuvosa (p < 0,01) e o volume de água foi positivamente correlacionado com a abundância de B. rehni. A larva de B. rehni pode ser diferenciada da larva de B. fernandezianum, única espécie do gênero com larva descrita, pelo número de setas no premento e pelo padrão de coloração na região apical do fêmur. Pela primeira vez é reportada a associação dessa espécie com fitotelmata de Guzmania brasiliensis.

The last-stage larva of Bromeliagrion rehni Garrison in De Marmels & Garrison, 2005 is described and illustrated and bionomics and habitat information on this species are provided. The study was conducted in the Reserva Florestal Adolpho Ducke, located near Manaus, state of Amazonas, Brazil.Twelve samplings were done between April, 2003 and April, 2005: six in the rainy season and six in the dry season. In each sampling month, 12 bromeliads (Guzmania brasiliensis Ule, 1907, Bromeliaceae) were collected, six of which were terrestrial and six epiphytic, yielding144 samples. A total of 75 specimens of B. rehni were collected. The relationship between larval B. rehni abundance and the measured environmental parameters (volume (ml), pH, season and stratum) was significant (ANCOVA, F = 5.296, d.f. = 130, p < 0.001). Larvae were most abundant in the rainy season (p < 0.01) and water volume was positively related to the abundance of B. rehni. Larvae of B. rehni can be distinguished from those of B. fernandezianum (the only species in the genus with described larvae) by the number of setae in the prementum and by the color of the apical region of the femur. The association of this species with phytotelmata of G. brasiliensis is reported here for the first time.
