| Summary: | The purpose of this work was to determine the diversity and population fluctuations of calliphorid flies in the Biological Reserve of Tinguá (ReBio-Tinguá), Nova Iguaçu, state of Rio de Janeiro, Brazil and to correlate their occurrence with the environmental variables of temperature, rainfall and relative air humidity. Specimens of Diptera were collected monthly between June 2002 and January 2005 using four traps placed at four points along a trail and exposed for 48 hours. The traps were baited with sardines and the trapped insects were stored in 70% alcohol. It was collected 8,528 calliphorids, thirteen species were identified among the blowflies including Laneela nigripes Guimarães 1977, Chrysomya megacephala (Fabricius, 1794), C. albiceps (Wiedemann, 1819), C. putoria (Wiedemann, 1830), Chloroprocta idioidea (Robineau-Devoidy, 1830), Cochliomyia macellaria (Fabricius, 1775), Hemilucilia semidiaphana (Rondani, 1850), H. segmentaria (Fabricius, 1805), Lucilia eximia (Wiedemann,1819), L. cuprina (Wiedemann, 1830), Paralucilia pseudolyrcea (Mello, 1969), Mesembrinella sp. and Eumesembrinella pauciseta (Aldrich, 1922). No significant correlation was found between the abundance of blowflies and the temperature and relative air humidity. Only C. megacephala and C. albiceps showed a positive and significant correlation with rainfall. An analysis of grouping by month (UPGMA) revealed no seasonal difference in the composition of the community, indicating that the community of calliphorid flies is probably more influenced by the ecological niches occupied by each species than by the seasons of the year.
O presente trabalho objetivou determinar a flutuação populacional de califorídeos da Reserva Biológica do Tinguá (ReBio-Tinguá), Nova Iguaçu, RJ e correlacionar sua ocorrência com as variáveis ambientais de temperatura, precipitação e umidade relativa do ar. Os dípteros foram coletados mensalmente entre junho de 2002 e janeiro de 2005 utilizando quatro armadilhas instaladas em quatro pontos de uma trilha e expostas por 48 horas. Como atrativo utilizou-se sardinha e os insetos capturados foram conservados em álcool 70%. Foram coletados 8.528 califorídeos; entre estes, foram identificados treze espécies incluindo Laneela nigripes Guimarães 1977, Chrysomya megacephala (Fabricius, 1794), C. albiceps (Wiedemann, 1819), C. putoria (Wiedemann, 1830), Chloroprocta idioidea (Robineau-Devoidy, 1830), Cochliomyia macellaria (Fabricius, 1775), Hemilucilia semidiaphana (Rondani, 1850), H. segmentaria (Fabricius, 1805), Lucilia eximia (Wiedemann,1819), L. cuprina (Wiedemann, 1830), Paralucilia pseudolyrcea (Mello, 1969), Mesembrinella sp. and Eumesembrinella pauciseta (Aldrich, 1922). Não foi encontrada correlação significativa entre a abundância dos califorídeos e a temperatura e umidade relativa do ar. Somente C. megacephala e C. albiceps apresentaram correlação positiva e significativa com a precipitação. A análise de agrupamento dos meses (UPGMA) mostrou que não houve diferença na composição da comunidade em relação à sazonalidade, indicando que a comunidade de califorídeos é provavelmente mais influenciada pelos nichos ecológicos ocupados por cada uma das espécies do que pelas estações do ano. |
