| Este estudo foi realizado no período de agosto de 1999 a julho de 2000 com o objetivo de conhecer os parasitóides de Chrysomya megacephala (Fabricius, 1794) (Diptera, Calliphoridae) e avaliar sua dinâmica populacional no Instituto Oswaldo Cruz (IOC/ FIOCRUZ) e Jardim Zoológico, na cidade do Rio de Janeiro, RJ. As coletas foram realizadas semanalmente através da exposição de larvas de terceiro instar da mosca e seu substrato de criação, carne bovina moída em putrefação. Foram identificadas três espécies de himenópteros parasitóides: Tachinaephagus zealandicus Ashmead, 1904 (Encyrtidae), Pachycrepoideus vindemiae (Rondani, 1875) (Pteromalidae) and Nasonia vitripennis (Walker, 1836) (Pteromalidae). Nos dois locais, T. zealandicus foi a espécie com maior taxa... |

| Abstract Aleurocanthus woglumi (Ashby, 1915) is an important agricultural pest that causes yield losses of 20-80% in citrus plants by removing plant nutrients while feeding and allowing the formation of sooty mold. The objective of this study was to evaluate physiological changes in citrus plants in response to A. woglumi infestation under field conditions. The experiment was conducted in a citrus orchard in Paço do Lumiar, Maranhão, Brazil. Thirty-two citrus plants were used, including eight of each of the following varieties: Tahiti lime, Tanjaroa tangerine, Nissey tangerine, and Ponkan tangerine. Four random plants with A. woglumi infestation and four plants free from this pest were selected from each variety. The physiological parameters evaluated were... |

| Os flebotomíneos são os vetores naturais de alguns agentes etiológicos de doenças humanas e de animais, tais como protozoários do gênero Leishmania Ross, 1903. A fauna flebotomínica no Mato Grosso do Sul é relativamente bem conhecida e até o momento compõe-se de 54 espécies. O presente estudo baseia-se no levantamento de flebotomíneos em área urbana de 18 municípios com transmissão de leishmaniose visceral no Estado do Mato Grosso do Sul, com objetivo de verificar as principais espécies e fornecer subsídios para o programa de controle das leishmanioses. As coletas foram realizadas com armadilhas automáticas luminosas, instaladas mensalmente durante três noites consecutivas, das 18:00 horas às 6:00, no período de dois anos. Foram coletadas 36 espécies... |

| Ants are among the most common arthropods that colonize termite nests. The aim of this study was to identify the ant fauna associated to termite nests found in a cacao plantation in the county of Ilhéus, Bahia, Brazil, with emphasis on the fauna that uses the nests as foraging and/or nesting environment. For this purpose, 34 active, decadent and abandoned nests of Nasutitermes corniger, N. ephratae and Nasutitermes sp., with different volumes and degrees of activity, were dissected. A total of 54 ant species, belonging to 23 genera and five subfamilies, was found in the constructions. The active, decadent and abandoned termite nests presented, respectively, six, eight and 48 ant species. Crematogaster acuta and Ectatomma tuberculatum were the most frequent... |

| A test-chamber (K&L-Chamber) made of cardboard and acrylic plastic, and consisting in four sections (A, B, C and D) was developed by Klowden & Lea (1978) for Aedes aegypti host-seeking behavior studies. Later, Foster & Lutes (1985) also used an identical chamber to successfully evaluate the efficacy of electronic repellers. It was described here a modified K&L-Chamber for behavioral studies of Ae. aegypti adults. The chamber was made in polystyrene, consisting of three sections (A, B and C) and using a human hand and a fluorescent lamp as stimulus to attract the mosquitoes. The suitability of the present test-chamber was validated assaying 80 replicates and releasing 10 Ae. aegypti females in each replicate. The females were... |

| Como parte do Projeto PROVIVE, foram analisadas a riqueza de espécies, a composição taxonômica, a proporção de espécies raras e a constância taxonômica ao nível de família relacionada à riqueza de espécies, em comunidades de Coleoptera, em Vila Velha, Ponta Grossa, Paraná. Os dados foram obtidos a partir de coletas através de armadilha malaise no estrato do sub-bosque de cinco áreas com diferentes graus de intervenção antrópica, de setembro de 1999 a agosto de 2000. As 52 semanas de amostragem nas cinco áreas resultaram na coleta de 10.822 indivíduos de 1659 espécies. Todas as áreas apresentaram alta riqueza de espécies e diversidade, como indicado por vários índices. A área em estágio mais avançado de sucessão vegetal foi menos rica do que aquelas em... |

| Abstract Three new species, Bruggmanniella miconiae sp. nov., B. notatae sp. nov. and B. sideroxyli sp. nov., are described and illustrated. The new species are associated, respectively, with Miconia theaezans (Bonpl.) Cogn (Melastomataceae), Ocotea notata (Nees and Mart.) Mez (Lauraceae) and Sideroxylon obtusifolium (Roem. and Schult.) T. D. Penn. (Sapotaceae), respectively. The first one was collected in Dores do Indaiá city, Minas Gerais, Brazil; and the two others were collected in Mangaratiba city, Rio de Janeiro, Brazil.

| ABSTRACTWe analyzed the effects of Bacillus sphaericus on Anopheles larvae and on the associated insect fauna in fish farming ponds. Five breeding sites in the peri-urban area of the city of Manaus, AM, Brazil, were studied. Seven samples were collected from each breeding site and B. sphaericus was applied and reapplied after 15 days. The samples were made at 24 h before application, 24 h post-application and 5 and 15 days post-application. We determined abundance, larval reduction and larval density for Anopheles, and abundance, richness, Shannon diversity index and classified according to the functional trophic groups for associated insect fauna. A total of 904 Anopheles larvae were collected and distributed into five species. Density data and larval... |

| Orthoptera assemblages associated with macrophytes of floodplain lakes of the Paraná River. The Orthoptera assemblage composition varies considerably, depending on habitat type. This study examines the spatiotemporal relationship between plant diversity, hydrometric level, environmental variables and the Orthoptera richness and abundance in floodplain lakes connected permanently or temporarily with the main channel of the Paraná River. The grasshoppers were collected fortnightly (April 2006May 2007). A total of 17 species were recorded and classified according to their frequency of occurrence in constant (7), accessory (4), or accidental (6) species. In the two lakes, the greater species richness and abundance was recorded in summer, thereby coinciding... |

| Abstract Aedes aegypti is the principal vector of arboviral pathogens that may cause diseases as dengue fever, chikungunya and zika. The harmful environmental effects of commercial pesticides coalesced with the development of insecticide-resistant populations encourage the discovery and generation of new alternative products as a tool to reduce the incidence of vector-borne diseases. In this work, through the classic three component Strecker reaction of commercial benzaldehydes, cyclic secondary amines and KCN, a new series of nine α-amino nitriles, girgensohnine analogs, has been synthetized and screened for larvicide and adulticide properties against A. aegypti, one of the dominant vectors of dengue, chikungunya and zika in tropical and subtropical areas... |
