“…Chrysomya albiceps is highly predatory and this may account for the change of location and reduction of populations of necrophagous native species (Faria et al 1999;Faria & Godoy 2001;Andrade et al 2002;Faria et al 2004).…”

ABSTRACT. Rate of development of forensically-important Diptera in southern Brazil. Dipteran larvae were collected from rabbit (Oryctolagus cunniculus L.) carcasses during the four seasons in 2005 in the southernmost state of Rio Grande do Sul, Brazil. The larvae were fed ground beef at ambient temperatures following collection from carcasses. The development of each species under these conditions was estimated. The most abundant species in the carcasses were Lucilia eximia (Wiedemann) and Chrysomya albiceps (Wiedemann) (Calliphoridae), and they were found in all seasons. The data were fitted to a linear model that describes the relationship between temperature and linear developmental rating. These two species are primary forensic indicators in southern Brazil. Other species such as Hemilucilia semidiaphana (Rondani) (Calliphoridae), Synthesiomyia nudiseta (Wulp), Muscina stabulans (Fallen) (Muscidae), and Fannia pusio (Wiedemann) (Fanniidae) were forensically less important because they only occurred in high frequency in certain seasons and during the first days of carcass decomposition.KEYWORDS.

Larvas de dipterous foram coletadas em carcaças de coelho-doméstico (Oryctolagus cunniculus L.) ao longo das quatro estações de 2005 no extremo-sul do Rio Grande do Sul, Brasil. As larvas foram alimentadas com carne bovina moída e acondicionadas em temperatura ambiente. O desenvolvimento de cada espécie foi acompanhado nestas condições. As espécies mais abundantes na carcaça foram Lucilia eximia (Wiedemann) e Chrysomya albiceps (Wiedemann) (Calliphoridae) em todas as estações. Os dados foram ajustados a um modelo linear da relação entre a taxa de desenvolvimento destas espécies e a temperatura média diária do ambiente. Estas duas espécies são as principais indicadoras forense no sul do Brasil. Outras espécies como Hemilucilia semidiaphana (Rondani) (Calliphoridae), Synthesiomyia nudiseta (Wulp), Muscina stabulans (Fallen) (Muscidae) e Fannia pusio (Wiedemann) (Fanniidae) foram menos importantes porque ocorreram em alta abundância em determinadas estações do ano no decorrer dos primeiros dias de decomposição.

“…Within the species belonging to Calliphoridae, different trophic behaviours, as well as changes in food preferences, have been described during development. The calliphorid species Lucilia, Calliphora, Protophormia and Phormia are exclusively saprophagous, whereas the young larvae of the Chrysomya species feed on decomposing organic matter but the second and third stage larvae become predatory on the larvae of other Diptera (Ulyett 1950, Braack & Retief 1986, Faria & Godoy 2001. These feeding habits have direct consequences on the composition of bodybreeding fauna (Grassberger et al 2003).…”

“…Recently, Faria et al (1999) and Faria and Godoy (2001) investigated facultative predation rates on third instar larvae of C. macellaria, C. putoria and C. megacephala by third instar larvae of C. albiceps in no-choice, two-choice and three-choice situations. The highest predation rate occurred for C. macellaria larvae, suggesting that C. albiceps has a higher predation impact on C. macellaria than the other prey species.…”

“…Statistical analysis of the frequency distribution of dispersing blowfly larvae revealed that aggregated patterns of distribution emerge as a consequence of dispersal, LDBF and MNR have been supported by research fellowships from Fapesp (01/13920-3, 01/06368-2); GSR and CJVZ have been supported by research fellowships from Capes and CNPq, respectively.rufifacies (Macquart), C. putoria and C. megacephala, and the native species C. macellaria have been carried out (Wells & Greenberg 1992a,b,c, Faria et al 1999, Reis et al 1999, Faria & Godoy 2001, no systematic study associating blowfly larval predation and dispersal is available in the literature. Here, we investigated the larval aggregation patterns of C. albiceps and C. macellaria in single and double species experiments in order to evaluate the possible associations between predation and dispersal.…”
