Semiweekly collections were carried out over 48 months (96 collections). The traps were suspended at a height of 1.20 m above the ground for a period of 48 hours for each collection. To trap and collect the flies, four plastic traps (35 cm x 15 cm) were placed 100m apart each other in the studied area. The bait used was based on fish (sardine) in decomposition. The insects caught were killed by asphyxiation with 70% ethanol inside the trap. After asphyxiation all specimens were put into plastic pots containing 70% ethanol. The specimens were taken to the Laborat?rio de Transmissores de Leishmanioses (Setor de Entomologia M?dica e Forense) - IOC/FIOCRUZ, RJ, where they were separated by the collection day, counted and then identified using a stereoscopic microscope and the dichotomous keys for families and species. The abundance of Calliphoridae flies was statistically analyzed using the Statistica 7.1 program (StatSoft 2005) for the non-parametric test Kruskal-Wallis one way ANOVA (p< 0.05). Also the Kendall Tau Correlation test, Mann-Whitney (significance of 95%; p<0.05) and chi-square test (?2) were used to analyze. The Shannon-Wiener diversity index, Bray-Curtis similarity and Euclidean Distance were used. A total of 4,531flies were collected. These flies belonged to ten (10) species of the Calliphoridae family: Chrysomya megacephala (Fabricius, 1794) (86.40%), Chrysomya albiceps (Wiedemann,1819) (5.72%), Cochliomyia macellaria (Fabricius, 1775) (4.94%), Chrysomya putoria (Wiedemann, 1818) (2.10%), Lucilia eximia (Wiedemann, 1819) (0.30%), Cochliomyia hominivorax (Cocquerel, 1858) (0.22%), Chloroprocta idioidea (Robineau-Desvoidy, 1930) (0.20%), Hemilucilia segmentaria (Fabricius, 1805) (0.04%), Hemilucilia semidiaphana (Rondani, 1850) (0.04%), Lucilia cuprina (Wiedemann,1830) (0.04%). The species C. megacephala was the one that presented the greatest abundance. Spring was the preferred season for all species; temperatures between 30.5 and 32.40C and relative humidity between 56.8 and 61.7% were considered those where there was a frenzy of oviposition; the full and new moons were the phases during which there was a higher occurrence of flies; Megaselia scalaris occurred more frequently in the most abundant Calliphoridae species in the same season of the year thus allowing greater dispersion of eggs; Calliphoridae species had a higher rate survival with increased food resources resulting from the polluting activity / Este trabalho foi realizado entre agosto de 2007 e julho de 2011, no Munic?pio de Itabora?, RJ, Brasil, e teve como objetivo identificar as esp?cies de Calliphoridae existentes em uma ?rea de mangue, quantificar as predominantes, destacando as propor??es de machos e f?meas, e tamb?m analisar a influ?ncia de fatores abi?ticos, tais como temperatura, umidade do ar e fases lunares; e ainda relacionar a abund?ncia, a riqueza, a diversidade e a similaridade entre os per?odos de coletas, rela??es ecol?gicas entre as esp?cies da entomofauna da mesma fam?lia e a rela??o ecol?gica entre Calliphoridae e Phoridae parasit?ides dentro da ?rea de Prote??o Ambiental de Guapi-Mirim (APA de Guapi-Mirim), em Itabora?. Durante 48 meses, foram realizadas 96 coletas, uma a cada 15 dias. Em todas as capturas, foram utilizadas armadilhas confeccionadas em recipiente pl?stico com 35 cm de altura e 15 cm de di?metro. Cada uma das quatro armadilhas foi suspensa a uma altura de 1,20 m do solo contendo 100g de isca de peixe (sardinha) em decomposi??o por um per?odo de 48 horas. Ap?s cada captura, todos os esp?cimes foram mortos no interior das armadilhas por asfixia utilizando etanol 70%. Em seguida todos os indiv?duos foram acondicionados em potes pl?sticos, contendo etanol a 70% e encaminhados ao Laborat?rio de Transmissores de Leishmanioses (Setor de Entomologia M?dica e Forense), IOC-FIOCRUZ, RJ, em seguida todos os esp?cimes foram separados por dia de coleta, identificadas e quantificadas. Para tal procedimento utilizou-se um microsc?pio estereosc?pico e chaves dicot?micas para a identifica??o da fam?lia e das esp?cies. As an?lises estat?sticas foram feitas utilizando o programa estat?stico Statistica 7.1 (STATSOFT, 2005), atrav?s do teste de Kruskal- Wallis one way ANOVA, teste de qui- quadrado (?2), Mann-Whitney e correla??o de Kendall Tau (p<0,05). Foram utilizados os ?ndices de diversidade de Shannon-Wiener e similaridade de Bray-Curtis, assim como a Dist?ncia Euclidiana. Foram capturadas 4531 moscas pertencentes a dez (10) esp?cies da fam?lia Calliphoridae: Chrysomya megacephala (Fabricius, 1794) (86,40%), Chrysomya albiceps (Wiedemann,1819) (5,72%), Cochliomyia macellaria (Fabricius, 1775) (4,94%), Chrysomya putoria (Wiedemann, 1818) (2,10%), Lucilia eximia (Wiedemann, 1819) (0,30%), Cochliomyia hominivorax (Cocquerel, 1858) (0,22%), Chloroprocta idioidea (Robineau-Desvoidy, 1930) (0,20%), Hemilucilia segmentaria (Fabricius, 1805) (0,04%), Hemilucilia semidiaphana (Rondani, 1850) (0,04%), Lucilia cuprina (Wiedemann,1830) (0,04%). A esp?cie C. megacephala foi aquela que apresentou a maior abund?ncia, a primavera foi a esta??o do ano em que todas as esp?cies mostraram maior prefer?ncia; as temperaturas compreendidas entre 30,5 e 32,40C e a umidade relativa do ar entre 56,8 e 61,7% foram consideradas aquelas onde houve frenesi de oviposi??o; nas luas cheias e novas houve maior ocorr?ncia de moscas capturadas; Megaselia scalaris se utilizou de esp?cies abundantes nas mesmas esta??es do anos em que ela ocorreu com maior frequ?ncia, possibilitando assim maior dispers?o de ovos; a maior disponibilidade de recursos alimentares resultantes da atividade poluidora tempor?ria ofereceram uma melhor condi??o de sobreviv?ncia para as esp?cies os Calliphoridae.
