    Plecoptera (Insecta) imaturos da Amazônia brasileira
    (Universidade Federal do Pará, 2013-05-06) RIBEIRO, José Moacir Ferreira; GORAYEB, Inocêncio de Souza; http://lattes.cnpq.br/2391620537048479
    This study presents for the first time, a classification of immature Plecoptera Brazilian Amazon based on specimens collected during the development of the thesis and other existing collections that were borrowed for the study (INPA, MZUSP, IEPA, MPEG). The classification is based on external morphological characters, both, those already used by other authors as others added in this study. Recent collections were made at the following locations (bacins of Apeú River and Peixe-boi River, Mountain Martírios- Andorinhas, National Forest Caxiuanã, National Forest Amapá, Mountain Tepequém). Collection methods in the field was done by net for aquatic insect with 0.4 cm mesh, steel sieve with 0.7 cm mesh and trawl with 0.3 cm mesh. After harvesting the nymphs were screened in plastic trays and copies in advanced stage of development, were packed in small styrofoam box and then transported to creation. Nymphs were grown to adults to obtain the precise relationship there between. We describe the techniques of creating new methods in plastic cups made in the very stream where they were collected and cement tank in Campus Research Goeldi Museum. Physic-chemical parameters were measured in the water collection sites as temperature, pH, dissolved oxygen and electrical conductivity, and environmental characterization of the type of background, adjacent forests. The material studied contains: nymphs of various instars that were not associated with adults, nymphs and exúviae that were created and associated with adults, adults obtained by collection and by creating nymphs. The immature been described using the terminology Hynes (1941), Harper & Stewart (1984), Froehlich (1984), Couceiro & Hamada (2003) and Olifiers et al. (2005). Were described six nymphs of the species Anacroneiria marlieri, A. minuta, A. manauensis, Macrogynoplax delicata, M. pulchra and Enderleina froehlichi; nymphs of fourteen morphospecies, eleven of Anacroneuria genus: A. sp. n. 1, A. sp. n. 2, A. sp.JMFR1, A. sp.JMFR2, A. sp.JMFR3, A. sp.JMFR4, A. sp.JMFR5, A. sp.JMFR6, A. sp.JMFR7, A. sp.JMFR8, A. sp.JMFR9, A. sp.JMFR10, A. sp.JMFR11, two of Macrogynoplax genus: M. sp.JMFR1, M. sp.JMFR2 and one of Enderleina: E. sp.JMFR1. The morphospecies are certainly new species to be described in due course after the association with adults. It presents, for the first time, a sort key for the species and morphospecies of immature Brazilian Amazon.

    Simulídeos (Diptera: Nematocera) das bacias do leste do estado do Pará, com ênfase na Serra dos Martírios-Andorinhas
    (Universidade Federal do Pará, 2008) SANTOS, Emerson Monteiro dos; GORAYEB, Inocêncio de Souza; http://lattes.cnpq.br/2391620537048479
    This study adds to our knowledge of the medically important black flies (Diptera: Simuliidae) of eastern Para state, Brazil, in terms of geographic distribution of species; taxonomic key for species identification based on pupae; estimation species richness; daily haematophagic activity; aspects of the relations of limnological and meteorological factors in relation to simulid and associated aquatic insect population dynamics; biological conservation state; and similarity of three areas (Northeast-Atlantic, “Serras das Andorinhas e Carajás”) based on an environmental protocol and black flies species. Previously, 14 species of black flies had been registered in the study area: S. nigrimanum, S. incrustatum, S. minusculum, S. quadrifidum, S. limbatum, S. perflavum, S. iracouboense, S. rorotaense, S. spinibranchium, S. subpallidum, S. pertinax, S. subnigrum, S. brachycladum, and S. goeldii. A new identification key for species of Simuliidae pupae is provided for eastern Pará state. The important species for public health, such as S. nigrimanum, S. incrustatum, S. rorotaense, S. minusculum, S. subnigrum, and S. pertinax, have been found in diverse environments, with ample geographic distribution and new records of occurrence throughout Pará and eastern Amazonia. Studies of daily haematophagic activity of S. rorotaense, S. minusculum, and S. pertinax were made in the months of January, April, August, and December of 2006, at “Serra das Andorinhas” in southeastern Pará. Biting activity is correlated mainly with air temperature and relative humidity and exhibits two daily activity peaks in the early morning and late afternoon. Biting preference for selected regions of the human body also was seen to differ among species. Black fly species and their associated aquatic insects are assigned to two groups based on water characteristics. These are correlated in greater or minor degree with water outflow, speed, depth, width, alkalinity, and iron concentration in both studied regions (Northeast-Atlantic Coast and “Tocantins-Araguaia”). Environmental conditions in the “Serra das Andorinhas” were observed to have been well conserved, but those were altered at “Serra dos Carajás” and the Northeast-Atlantic Coast areas. A close similarity in black flies species composition was observed between the “Serra das Andorinhas” and the “Serra dos Carajás” areas, followed by their similarity with the Northeast-Atlantic Coast.
