“…This increase in survival on diets with a higher proportion of protein is due to behavioral characteristics of these species. Furthermore, strains of the species that were used in this experiment are already adapted to artificial diets composed of fish meal in high proportion for several generations (Ribeiro et al, 2000a;2000b;2001;Krüger et al, 2003;2004). The adaptation of the high proportion of proteins is a prerequisite for the maintenance of predators in the laboratory.…”

“…The adults were fed with a diet composed of milk powder, sugar and fish meal, in a ratio of 2:2:1, respectively. The diets were modified by Ribeiro et al (2000a) and Krüger et al (2004) from Hogsette and Koehler (1992) and Hogsette et al (2002) that used Gainesville and Budapest diets. The O. aenescens and O. albuquerquei larvae were fed according to Ribeiro et al (2000b) and Kruger et al (2003) modified from Hogsette and Washington (1995) and Farkas et al (1998), who used Gainesville and Budapest diets for larvae.…”

The purpose of this study was to evaluate the survival, development time and morphological measures of immature Ophyra aenescens and Ophyra albuquerquei on different diets. Different proportions of protein and carbohydrates were offered for each species in 10 vials containing 30 eggs each. The vials were placed in a germination chamber at 30°C, relative humidity above 75% and photoperiod of 12 hours. Every day a vial was removed and mortality was evaluated and on the tenth day the length of the cephalic-pharyngeal skeleton (EC) and body size (G) of larvae that survived were evaluated. Survival was higher in diets with more protein (P<0.001). Between the species, mortality was more pronounced in O. albuquerquei in all diets (P<0.001). The EC (P<0.01) and G (P<0.01) showed the same sizes in the diets with higher protein content. For the production of pupae of these species, the diet with more protein and fewer components is more appropriate, and the production is higher in O. aenescens than in O. albuquerquei.

“…Conforme haja variação na força de mortalidade por idade específica, poderá haver influência significativa na fecundidade das fêmeas de uma população, caso esta força seja maior em intervalos etários onde haja mais oviposições. Isto foi verificado para Ophyra albuquerquei Lopes, 1986 (Diptera, Muscidae), através de análise qualitativa dos dados de sobrevivência e fecundidade e foi constatado que após sucessivos picos de oviposição ocorreram picos de mortalidade de fêmeas, o que poderia indicar um alto custo fisiológico (Krüger et al 2004). Este custo se dá, geralmente, nos primeiros dias de uma coorte de uma espécie que tenha alta velocidade de desenvolvimento como é o caso de M. stabulans.…”

ABSTRACT. Entropy estimation in Muscina stabulans (Fallén) (Diptera, Muscidae) under laboratory conditions. Entropy (H) as a concept in demography was adapted from that of physics to quantify the impact of mortality on life expectancy and to quantitatively demonstrate mortality tendencies in experimental populations. Entropy was estimated for 160 pairs of Muscina stabulans (Fallén, 1817) in a climate-controlled chamber (24.8ºC ± 0.6ºC, relative humidity 70 -80%, 12 h photophase). Both sexes had H values intermediate to those theoretically expected (0.0 -0.5), showing that the survival curve is rectangular. The age-specific mortality distribution shows that mortality affects adults of this species in two ways. First, mortality is higher for 10 days from pupal emergence. Second, mortality again increases between 20-30 days after emergence. Small differences in mortality rates cause a greater overall impact on the survival of females.KEYWORDS. Life expectancy; mortality; population dynamics; survival.RESUMO. Estimativa de entropia de Muscina stabulans (Fallén) (Diptera, Muscidae) em condições artificiais. O conceito de entropia (H) foi adaptado da mecânica estatística para a demografia para quantificar o impacto da mortalidade na expectativa de vida e demonstrar quantitativamente a tendência da mortalidade em populações experimentais. Isto foi verificado para 160 casais de Muscina stabulans (Fallén, 1817) mantidos em câmara climatizada a 24,8ºC ± 0,6ºC, umidade relativa do ar entre 70 e 80% e fotofase de 12 horas. Nestas condições, machos e fêmeas apresentaram valores de H intermediários aos valores teóricos de H = 0 e H = 0,5 demonstrando que para esta espécie, a curva de sobrevivência é do tipo retangular. A distribuição da mortalidade por idade específica indicou que a força desse parâmetro age de dois modos sobre os adultos desta espécie. Em um, a mortalidade tem maior força nos intervalos compreendidos entre a emergência dos adultos e o 10° dia após este processo. No segundo modo, a força de mortalidade é maior entre o 20º e 30°d ias após a emergência, sendo que pequenas variações na mortalidade causam maior impacto na sobrevivência das fêmeas do que nos machos.PALAVRAS-CHAVE. Expectativa de vida; dinâmica populacional; mortalidade; sobrevivência.Muscina stabulans (Fallén, 1817) (Diptera, Muscidae) é uma espécie anautógena (Tirone et al. 1996), cosmopolita, com maior freqüência na Região Neotropical . No Brasil foi encontrada na Bahia, Paraná e São Paulo com preferência por ambientes urbanos (Linhares 1981;Carvalho et al. 1984), importante para a entomologia forense em países subtropicais (Liu & Greenberg 1989;Centeno et al. 2002)

“…However, the numerical dominance of the muscid species O. chalcogaster had not been described in previous studies in South America. Larvae of Ophyra species can occur in extremely diverse habitats, including dung, putrefied meat, and even decomposing vegetal matter, and they are also reported to prey upon larvae of Sarcophagidae, Calliphoridae, and Muscidae species (Skidmore, 1985;Pamplona & Couri, 1989;Krüger et al, 2004).…”

Cities in northeastern Brazil experience extreme rates of unsolved homicides, a situation that stimulates innovative procedures in the police work, such as forensic entomology. We surveyed necrophagous insects associated with carrion in a city exposed to high rates of homicides in Northeastern Brazil. The experiments were carried out in a rainforest fragment located in Recife, State of Pernambuco. Two pig carcasses were used as models, one in the dry and the other in the rainy season. The collection of adults was performed daily until the complete skeletonization of the carcasses. At least 32 Diptera species from the families Calliphoridae, Muscidae, Sarcophagidae, Fanniidae, Phoridae, Anthomyiidae, Piophilidae, and Stratiomyidae were registered, some of which have been previously documented on cadavers. A high richness of Diptera species was registered in all stages of decomposition. A strong overlap in the occurrence of most species was observed, which invalidates a defined entomological succession on the carcasses. Two species stood out in terms of abundance: Ophyra chalcogaster (Muscidae) and Chrysomya albiceps (Calliphoridae). The ubiquity of Hemilucilia semidiaphana (Calliphoridae) seems to confirm its preference for forest fragments exposed to low anthropogenic action. Our data contribute to expand the knowledge on the geographical distribution of forensically relevant species in the region and confirm the rapid dissemination of invasive Chrysomya species in forested areas.
