“…In a study by Beuter and Mendes (2013), Chrysomya albiceps (Wiedemann) did not breed in pig liver offered in similar conditions to those offered in the present experiments for M. domestica. Nevertheless, other authors have observed the development of C. albiceps in other mammalian liver (Al-Misned et al, 2002;Carvalho et al, 2007). Since time/ stage of decomposition influences the physical and biochemical characteristics of the rearing substrate (Nespoli et al, 1998); Beuter and Mendes (2013) have argued that the discrepancy between their results and those of other authors may be associated with the supply of liver in different stages of decomposition from the other studies.…”

Musca domestica (L. 1758) is a cosmopolitan species that presents a high degree of association with human environments. This fly has been encountered carrying several pathogens and has been found associated with animal carcasses and human corpses in various countries. In this study, the capacity of larvae of M. domestica to breed in various pig tissues was tested. Larvae of this species were transferred to flasks containing liver, abdominal fat, meat, lung and brain tissues. The flasks were maintained in an incubator at 25 ºC ± 1 ºC, 70%± 10% humidity, and with a 12h/12h light/dark photoperiod until the emergence of the imagoes. The rates of development of larvae were assessed. The larvae did not reach adulthood in fat and liver. Comparisons between data from different tissues indicated differences in the size, weight and development of larvae of the same age. Brain and muscle were the substrates that had the lowest frequencies of emergence of imagoes. A longer time for development was observed in the brain, while shorter times were observed in lung and intestine. Lung and intestine were also the substrates from which greater numbers of imagoes emerged. Larvae in muscle presented smaller size and lower weight. Because M. domestica is capable of breeding in various tissues in the laboratory, its breeding capacity and abundance in carrion may depend on the biological and environmental conditions encountered outdoors. The influence of the factors studied when used in forensic entomology, should be taken into account, especially as an indicator of postmortem interval.

Chrysomya albiceps (Wiedemann) has been encountered breeding in animal carcasses and human bodies in many geographical regions. This species is considered an important postmortem indicator for Medical Legal Forensic Entomology. Studies have also demonstrated its capacity to develop in various natural and semi-synthetic substrates. The present study was undertaken to examine the development of immature C. albiceps in four different pig tissues. Eggs of this fly were deposited in flasks containing liver, abdominal fat, meat, and brain tissues. The flasks were maintained in an incubator at 25 ± 1°C, 70 ± 10% humidity, and 12-h/12-h photoperiod until emergence of the imagoes. Samples of the larvae were taken from different tissues/substrates to be weighed and measured. Their respective rates of development were accompanied. Comparisons among data from the different tissues indicated differences in the size and rate of development of larvae of the same age. Males emerged, on average, 1 day before females. Considerations as to the differences encountered for the estimate of postmortem interval were elaborated and consequences for the accuracy of the inferences discussed. The results indicate that such inferences should consider the disparities in the development of larvae presented by this species in different tissues.
