The Calliphoridae are flies of great ecological, medical and sanitary importance because they are decomposers of organic matter, mechanical vectors of pathogenic agents, and causers of myiasis. This paper attempts to ascertain the diversity of Calliphoridae in the Tinguá Biological Reserve and correlate meteorological data (temperature, relative humidity of the air, and precipitation) with the occurrence of these flies. The study was conducted at a site in the Tinguá Biological Reserve, located in the municipality of Nova Iguaçu, state of Rio de Janeiro, Brazil. Four traps were set up using chicken viscera as bait. The experiment was conducted over the period of May 2001 to April 2002, with two monthly collections. The captured flies were killed with ether and conserved in 70% alcohol and identified in the Laboratory of Diptera Studies (UNIRIO) and the Laboratory of Vector Insect Biology and Control (FIOCRUZ), both headquartered in the city of Rio de Janeiro, RJ, Brazil. A total of 1,987 insects were captured, 37.5% belonging to the family Calliphoridae, 29.4% to Muscidae, 16.0% to Sarcophagidae, and 17.1% to other families. The most representative species found was Phaenicia eximia (47.0%), followed by Hemilucilia semidiaphana (23.6%), Mesembrinella bellardiana (13.7%), Hemilucilia segmentaria (7.5%), Chloroprocta idioidea (4.9%), Chrysomya albiceps (1.2%), Chrysomya megacephala (0.9%), Phaenicia sericata (0.6%), Eumesembrinella sp. (0.5%), and Chrysomya putoria (0.1%). Large numbers of Calliphoridae were noted in May, June, September and January, coinciding with low rainfall and an average temperature of 21.8 to 27.0 degrees C. A negative correlation was found between the number of Calliphoridae captured and meteorological factors.
丽蝇科昆虫具有重大的生态、医学和卫生学意义，因为它们是有机物质的分解者、病原体的机械传播媒介以及蝇蛆病的致病源。本文旨在确定廷瓜生物保护区丽蝇科昆虫的多样性，并将气象数据（温度、空气相对湿度和降水量）与这些苍蝇的出现情况相关联。该研究在巴西里约热内卢州新伊瓜苏市廷瓜生物保护区的一个地点进行。使用鸡内脏作为诱饵设置了四个诱捕器。实验于2001年5月至2002年4月期间进行，每月收集两次。捕获的苍蝇用乙醚杀死，保存在70%的酒精中，并在位于巴西里约热内卢市的双翅目研究实验室（里约热内卢联邦大学）和媒介昆虫生物学与控制实验室（奥斯瓦尔多·克鲁兹基金会）进行鉴定。总共捕获了1987只昆虫，其中37.5%属于丽蝇科，29.4%属于蝇科，16.0%属于麻蝇科，17.1%属于其他科。发现的最具代表性的物种是卓越丽蝇（47.0%），其次是半透明黑绿蝇（23.6%）、贝拉迪纳美蝇（13.7%）、节段黑绿蝇（7.5%）、奇异绿蝇（4.9%）、白纹伊蚊（1.2%）、大头金蝇（0.9%）、丝光绿蝇（0.6%）、真美蝇属物种（0.5%）和腐臭金蝇（0.1%）。在5月、6月、9月和1月发现了大量的丽蝇科昆虫，这与低降雨量以及21.8至27.0摄氏度的平均温度相吻合。在捕获的丽蝇科昆虫数量与气象因素之间发现了负相关关系。
