“…The pattern of seasonality of L. eximia and C. albiceps observed in this study is in accordance with other studies in the same region (Vianna et al, 1998(Vianna et al, , 2004Souza et al, 2008;Krüger et al, 2010). There was a numerical dominance of L. eximia in winter, spring and autumn while C. albiceps was numerically dominant in summer at all sites, with a marked decrease in the frequency of occurrence of L. eximia in this season.…”

ABSTRACT. The blowfly species are important components in necrophagous communities of the Neotropics. Besides being involved in the degradation of animal organic matter, they may serve as vectors for pathogens and parasites, and also cause primary and secondary myiasis. The occurrence pattern of these species is well defined, yet it is still not very clear which of these environmental factors determine the structure of the assemblies. This paper was developed to evaluate the influence of mean temperature and relative humidity variation in the abundance and richness of blowflies in the Brazilian southernmost state, Rio Grande do Sul, where temperature variation is well marked throughout the year. To evaluate this objective, WOT (Wind Oriented Trap) were installed with beef liver as bait in three environments for 10 consecutive days in each month between July 2003 and June 2004. A total of 13,860 flies were collected distributed among 16 species with a higher frequency of Lucilia eximia (Wiedemann, 1819) and Chrysomya albiceps (Wiedemann, 1819). The mean temperature and relative humidity influence the richness of blowflies, with greater richness and abundance in late spring and early summer, whereas abundance was only influenced by temperature. Each species responded differently with respect to these variables, where L. eximia is not influenced by any of the two abiotic factors, despite the high abundance presented. This paper presents the results of the sensitivity for the presence or absence of species of Calliphoridae and on the variation of the abundance of these species under regime temperature changes and relative humidity with implications for public health and animal management.

As espécies de Calliphoridae são importantes componentes das comunidades de necrófagos na Região Neotropical. Além de estarem envolvidas na degradação da matéria orgânica animal podem também veicular diversos patógenos e parasitos, bem como causar míiases primária e secundária. O padrão de ocorrência destas espécies está bem definido, mas ainda não se tem muito claramente quais fatores ambientais determinam a estrutura destas assembleias. Desenvolvemos este trabalho com o objetivo de avaliar a influência da temperatura média e umidade relativa do ar na variação da abundância e riqueza de espécies de califorídeos no sul do Rio Grande do Sul, onde a variação da temperatura é bem demarcada ao longo do ano. Para avaliar este objetivo, foram instaladas armadilhas WOT (Wind Oriented Trap) com fígado bovino como isca em três ambientes por 10 dias seguidos em cada mês, entre julho de 2003 e junho de 2004. Foram coletados 13.860 dípteros distribuídos entre 16 espécies com maior abundância de Lucilia eximia (Wiedemann, 1819) e Chrysomya albiceps (Wiedemann, 1819). A temperatura média e a umidade relativa influenciaram a variação da riqueza de espécies de califorídeos, com maior riqueza e abundânci...

“…In the present study, these species were more abundant in the months with the highest temperatures, with a population peak in December 2002, although no significant positive correlation was found with the rise in temperature, a finding also reported by other authors (GUIMARÃES et al, 1978;OLIVEIRA, 1982;SOUZA & LINHARES, 1997;MARINHO et al, 2003). Nevertheless, COSTA et al (1992) and VIANNA et al (2004) found the highest frequency of these species in state of Rio Grande do Sul in the months of March, April and May, which correspond to autumn. Thus, it can be seen that population fluctuations are not restricted to the influence of environmental variables, but can also be affected by biotic factors (HANSKI & KUUSELA, 1987).…”

ABSTRACT. 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 (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. KEYWORDS.Seasonal abundance, diversity, Atlantic Forest, blowflies. (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.

“…Como é impossível conhecer a densidade absoluta dos insetos, a abundância e a fl utuação populacional são alternativas para se estimar e avaliar as populações no tempo e espaço (Vianna et al 2004). Esse conhecimento permite ainda a implementação de medidas de controle e o estabelecimento de espécies indicadoras de qualidade ambiental.…”

-Monthly collections were made using two traps 5 m apart exposed for 48h, containing sardines and installed at points: A -at the edge (500 m from the entrance of the Reserve); B -1200 m from the entrance and 1000 m inside the forest; and C -1700 m from the entrance and 500 m inside the forest. The purpose was to evaluate the abundance and richness of calliphorid species as a function of the environmental conditions using Pearson's correlation, compare the richness of the areas using ANOVA and Tukey's test, compare the abundances of the areas by the Kruskal-Wallis test, and also assess the possible infl uence of the anthropic presence. Rare, intermediary and common species were identifi ed. The collection totalized 8515 Calliphoridae belonging to 26 species, with a predominance of females. None of the 13 species considered common presented a correlation between abundance and temperature: only Cochliomyia hominivorax (Coquerel) and Chrysomya megacephala (Fabricius) were correlated with humidity and only Mesembrinella semihyalina Mello with precipitation. This parameter was the only climatic variable correlated with richness. The greatest abundance and richness of calliphorids occurred in September 2006. From the 13 common species, seven were considered synanthropic, indicating the effect of anthropic action in this site.
