Item Acesso aberto (Open Access) Estudo de Simuliidae (Diptera : Nematocera) e seus criadouros em igarapés do município de Santo Antônio do Tauá, estado do Pará, Brasil(Universidade Federal do Pará, 2001-05-03) SANTOS, Emerson Monteiro; GORAYEB, Inocêncio de Souza; http://lattes.cnpq.br/2391620537048479Considering the importance of black flies to human and animal health and to stream ecology, the simuliid fauna of Santo Antônio do Tauá. Pará state, northern Brazil, was studied through determination of the breeding habitat, introduction in streams of artificial breeding substrates for colonization by larvae, analysis of the aquatic insects associated with simuliid breeding sites, biting times and frequencies of anthrophilic black fly species, qualitative and quantitative analyses of the vegetation at breeding sites, physical and chemical analyses of stream water at these sites, analyses of local weather conditions, and morphometrics of immature Simulium quadrifidum to determine the number of larval instars. The aquatic insect faunas and the respective relative abundances of Simuliidae in two streams were studied. The species that were collected are Simulium perflavum, Simulium quadrijidum, Simulium incrustatum and Simulium goeldii. The immature forms of Simulium perflavum were the predominant ones in disturbed environments, clear waters. Simulium quadrifidum predominated in generally unaltered, black water environments, with low nutrient levels. Simulium incrustatum was more abundant in environments with low vegetation and found Only in clear waters. Simulium goeldii was registered only in areas of primary forest (that is, those showing little alteration) and was more abundant in black waters. The factor that most interfered with simuliid larvae colonizing the artificial substrates was the constant oscillation in the water level of the streams during the time that these substrates were exposed in the water. Aquatic insects were more abundant during the dry season. The biting habits of female Simulium incruslatum were studied for the first time in Pará: two daily peaks in biting frequency were observed with human volunteers, one in the morning and the other in the afternoon, with biting frequencies showing significant differences among vegetation types during these periods, and a significant negative correlation with air temperature in secondary forest during the dry season. The number of larval instars was determined for Simulium quadrificlum, and females of this species were found to oviposit only during the afternoon at 16:30h. New records of predators of adult black flies are presented.Item Acesso aberto (Open Access) O gênero microstrates lacordaire (Curculionidae : Baridinae): sistemática, filogenia e evolução da associação com palmeiras hospedeiras(Universidade Federal do Pará, 1997-03-11) ROCHA, Roberta Valente da; GORAYEB, Inocêncio de Souza; http://lattes.cnpq.br/2391620537048479A revision and phylogenetic analysis of the genus Microstrates is presented based on new characters discovered in the course of this study, and on others previously know from the literature. Eleven species are recognized, vvhich can be identified by the key presented. Two new species are described: Microstrates almiri sp. n., Caxiuanã and Belém, Pará; and M. pinrima sp. n., Monte Alegre, Pará. Microstrates bipunctatus Hustache, 1951 is considered a synonym of M. cocois Bondar, 1941. The phylogenetic analysis of the species Microstrates resulted in a hypotesis that may be expressed parenthetically as follows; ((M. cocoscampestris (M. abbreviatus (M. rufus, M. hatschbachi))) ((M. M. piririma) (M. cocais (M. cearanus, M. ypsilon) (M. cucullus, M. bondan)))). The first records of the palm hosts of M. almin sp. n., M. pirinma sp. n. and M rufus Hustache are presented. The species M. almin sp. n. and M. pirinma sp. n., collected in Pará state, represent the first record of Microstrates in the Amazonian Region. Ali species are redescribed and their most important structures for the identification are illustrated. The collection of Weevils in differents species of palms in Pará and Amazonas states confirms the hypothesis of a exclusive association of Microstrates with palms of the genera Syagrus, Butia and Cocos, and also that each species of Syagrus and Butia host only one species of Micro strates. The cladogram mapping and optimization of host palm associations of Microstrates supports the following hypothesis: association with the genus Syagrus is plesiomorphic, with Butia is apomorphic, and with the coconut (Cocos nucifera) is explained by colonization events.Item Acesso aberto (Open Access) Maruins (Diptera : Ceratopogonidae) que atacam o homem no litoral atlântico e estuário do rio Pará, Estado do Pará , Brasil(Universidade Federal do Pará, 2004-03-30) TRINDADE, Rosimeire Lopes da; GORAYEB, Inocêncio de Souza; http://lattes.cnpq.br/2391620537048479The dipterous family Ceratopogonidae has 125 genera and approximately 5360 species, 205 of which are extinct. More than 1400 species of Culicoides are known worldwide, and these are among the smallest blood-sucking flies in the world, measuring one to three mm in length. Some 96% of these species are obligate blood feeders on mammals (including human) and birds, and they are important vectors of human and animal viroses. Inspite of their epidemiological importance, few studies have been made of the biting behaviour and general ecology of Brazilian ceratopogonid specíes. This study surveyed the ceratopogonid species in two coastal areas of Pará State in northern Brazil, with reference to the hotus of the day when humans were bitten. The two coastal sampled were: the city of Marapanim on the northeastern Atlantic coast of Pará and Outeiro, a district of Belém on the Pará River estuary. Collections were made monthly between April and October 2003, using human bait and CDC traps. In total, 4083 specimes of Ceratopogonidae of 29 species in six genera were collected, 620 (21 species in five genera) from Outeiro and 3463 specimes (9 species in 4 genera) from Maripanim. The two faunae were seen to be sufficiently different from one another Leptoconops brasiliensis was the only species common to both sites. In Outeiro, the most abundant species were Culicoides batesi and C. denisae while in Marapanim these were C. maruim and C. phkbotomus. C. crucifèr and C. daviesi were collected in Outeiro and are registered for the first time fmm Brazil. C. denisae, C. phkbotomus and L. brasiliensis are reported for the first time for the state of Pará. In Outeiro, a significant negative correlation was found between air temperature and biting activity of C. batesi, C. cructfer and C. paramaruim. A significam positive correlation was found for biting activity and air relative humidity. In Marapanim, C. maruim biting activity showed a significant negative correlation with air temperature and significant positive with the air relative. The collected material, mounted on slides or in specimen tubes, is deposited in the Invertebrate Collection of the Museum Paranese Emílio Goeldi, Belém, Brazil.Item Acesso aberto (Open Access) Métodos de coletas de mosquitos (Diptera: Culicidae) alternativos ao de atração humana direta(Universidade Federal do Pará, 2007) VIEIRA, Paoola Cristina Bezerra; GORAYEB, Inocêncio de Souza; http://lattes.cnpq.br/2391620537048479Some methods capture of mosquitoes already had been developed, demonstrating that it had an evolution of the types of the trap to the long one of the time, however none has shown to be comparable to the direct human attraction (AH). This work had for objective, to test the methods alternative, developed to collect mosquitoes, including the development of new techniques, that can substitute the traditional method of direct human attraction. The study it was developed next to “Parque Ambiental de Belém”, Pará state, Brazil. The used methods were: traps CDC, CDC UV, Shannon, trap developed by Rocha, trap developed by Gorayeb and collect for AH direct. The traps were installed in six points, for six consecutive nights. Were captured 13,099 specimens of Culicidae of seven genera and 27 species, being Anopheles trianulatus the most abundant. The direct human attraction, what it collected greater diversity and abundance of mosquitoes, followed of the Shannon’s trap for abundance and Gorayeb’s trap for diversity.
