No. of bitstreams: 1 2008 - Fabio Silva de Souza.pdf: 3760278 bytes, checksum: d38f28c39076f3f01e4393fd0f31bc10 (MD5) Previous issue date: 2008-11-26 / The aim of this study was to characterize the association between the seasonality of dermatobiosis in bovines and its dipterans potential vectors as well as evaluate the association among the counts of Dermatobia hominis larvae and of potential vectors with meteorologicals data. It also had the objective of delimiting, quantifying and characterizing the geographical space of Serop?dica and Itagua? municipalities in relation to the favorable degrees for the occurrence of dermatobiosis in bovines in the rainy and dry periods using the Vista SAGA? 2007 information system. The seasonal fluctuation of D. hominis larvae was obtained by counts in ten bovines and of muscoids dipterans by capture using Adultrap? traps with sardine bait, once a month each, in three properties named A, B and C, localized in the Serop?dica, Paracambi and Itagua? municipalities, respectively, in the period of January 2006 to December 2007. The meteorological data of compensated mean temperature, pluvial precipitation and relative humidity were obtained in the Agricultural Ecology Station (22?48'S, 43?41'W and 33m of altitude). The associations between D. hominis larvae fluctuations, adult dipterans and climatological data were verified using the Spearman correlation test. Kruskal-Wallis and Mann-Whitney tests were used in the analysis of the significant differences between the rainy and dry periods in each property in the monthly average of D. hominis larvae, in the total monthly number and of dipterans family and in the analysis of other studies. In the elaboration of models by geoprocessing, some abiotic factors were used: occupation and covering of the land, altitude, declivity, soils and climatic factors, in which the evaluation, signature and monitorship functions of the Vista SAGA? 2007 program were applied. The infestation by D. hominis larvae in bovines was present during the 24 months of study in the three properties. A total of 18.966 dipterans potential vectors was captured, being 30,16% in the A property, 34,59% in the B property and 35,25% in the C property but there were no significant statistic difference between these. There was a positive and significant correlation (rs=0,63) between monthly averages of D. hominis larvae and relative humidity in 2006 at the A property; there was a positive and significant correlation between the total number of captured dipterans and pluvial precipitation (rs=0,80) and temperature (rs=0,60) at the B and C properties, respectively, in 2007. It was also observed a positive and significant correlation between the total number of captured dipterans of the Sarcophagidae family (rs=0,60) with the temperature in the C property in 2006, and between Muscidae (rs=0,67) and Calliphoridae (rs=0,76) with pluvial precipitation in the B property in 2007. There wasn t an association between monthly averages of D. hominis larvae and dipterans. It was verified a pattern lack in the association between monthly and periods fluctuations, rainy and dry of D. hominis larvae with the dipterans potential vectors fluctuations and of both with meteorologicals data. The geoprocessing allowed delimiting, quantifying and characterizing the potential of space temporal distribution of dermatobiosis in bovines. / Este estudo teve como objetivos caracterizar a associa??o entre a sazonalidade da dermatobiose em bovinos e seus d?pteros potenciais vetores, assim como avaliar a associa??o entre as contagens de larvas de Dermatobia hominis e de potenciais vetores com os dados meteorol?gicos. Teve tamb?m como objetivo, delimitar, quantificar e caracterizar o espa?o geogr?fico dos munic?pios de Serop?dica e Itagua? quanto aos gradientes de favorabilidade para a ocorr?ncia da dermatobiose em bovinos nos per?odos chuvoso e seco utilizando o sistema de informa??o Vista SAGA? 2007. A flutua??o sazonal de larvas de D. hominis foi obtida por contagens em dez bovinos e a de d?pteros musc?ides por captura, usando armadilhas Adultrap? com isca de sardinha, ambos uma vez ao m?s, nas tr?s propriedades denominadas A, B e C, localizadas nos munic?pios de Serop?dica, Paracambi e Itagua?, respectivamente, no per?odo de janeiro de 2006 a dezembro de 2007. Os dados meteorol?gicos de temperatura m?dia compensada, precipita??o pluvial e umidade relativa, foram obtidos na Esta??o Ecologia Agr?cola (22?48'S, 43?41'W e 33m de altitude). As associa??es entre as flutua??es de larvas de D. hominis, d?pteros adultos e dados climatol?gicos foram verificadas utilizando-se o teste de correla??o de Spearman. Os testes de Kruskal-Wallis e Mann-Whitney foram empregados na an?lise das diferen?as significativas entre os per?odos, chuvoso e seco, por propriedade, para a m?dia mensal de larvas de D. hominis, o n?mero mensal total e por fam?lia de d?pteros e na an?lise de dados publicados em outros estudos. Para a elabora??o dos modelos por geoprocessamento, utilizaram-se os fatores abi?ticos: uso e cobertura das terras, altitude, declividade, solos e fatores clim?ticos, aplicando-se as fun??es avalia??o, assinatura e monitoria do programa Vista SAGA? 2007. A infesta??o por larvas de D. hominis em bovinos esteve presente ao longo dos 24 meses de estudo nas tr?s propriedades. Um total de 18.966 d?pteros potenciais vetores foi capturado. Deste, 30,16% foram capturados na propriedade A, 34,59% na propriedade B e 35,25% na propriedade C, mas sem diferen?a estat?stica significativa entre estas. Houve correla??o positiva e significativa (rs=0,63) entre as m?dias mensais de larvas de D. hominis e umidade relativa, no ano de 2006, na propriedade A; houve correla??o positiva e significativa entre o n?mero total de d?pteros capturados e precipita??o pluvial (rs=0,80) e tamb?m com a temperatura (rs=0,60) nas propriedades B e C, respectivamente, no ano de 2007. Observou-se tamb?m correla??o positiva e significativa entre o n?mero total de d?pteros capturados da fam?lia Sarcophagidae (rs=0,60) com a temperatura na propriedade C no ano de 2006 e entre Muscidae (rs=0,67) e Calliphoridae (rs=0,76) com precipita??o pluvial na propriedade B em 2007. N?o ocorreu associa??o entre as m?dias mensais de larvas de D. hominis e de d?pteros. Constatou-se uma falta de padr?o na associa??o entre as flutua??es mensais e por per?odos, chuvoso e seco, das larvas de D. hominis com as flutua??es de d?pteros potenciais vetores e de ambas com os dados meteorol?gicos. O geoprocessamento permitiu delimitar, quantificar e caracterizar o potencial de distribui??o espa?o-temporal da dermatobiose nos per?odos chuvoso e seco.
