“…The dispersal of maggots away from carrion and from soil contaminated by carrion body fluids and by ammonium from the maggots can also accelerate the larval dispersal and have an impact on soil invertebrates and plants (Bornemissza 1957). Andrade et al (2002) used an acrylic channel to examine the influence of larval predation on larval dispersal in C. albiceps and C. macellaria. In two-species experiments, the number of C. albiceps larvae recovered was similar to the number initially released, whereas the number of C. macellaria larvae recovered was significantly smaller than that initially released.…”

Immature and adult stages of blowflies are one of the primary invertebrate consumers of decomposing animal organic matter. When the food supply is consumed or when the larvae complete their development and migrate prior to the total removal of the larval substrate, they disperse to find adequate places for pupation, a process known as postfeeding larval dispersal. Several important ecological and physiological aspects of this process were studied since the work by Green (Ann Appl Biol 38:475, 1951) 50 years ago. An understanding of postfeeding larval dispersal can be useful for determining the postmortem interval (PMI) of human cadavers in legal medicine, particularly because this interval may be underestimated if older dispersing larvae or those that disperse longer, faster, and deeper are not taken into account. In this article, we review the process of postfeeding larval dispersal and its implications for legal medicine, in particular showing that aspects such as burial behavior and competition among species of blowflies can influence this process and consequently, the estimation of PMI.

“…However, in the absence of C. macellaria, C. albiceps attacks C. putoria more often than C. megacephala (Faria & Godoy 2001). Attacks occur more often within the carcass, but may also occur outside, during larval dispersal (Andrade et al 2002, Gomes & Von Zuben 2005. Grassberger et al (2003) reported that the mortality rate of Lucilia sericata Meigen caused by predation from C. albiceps ranged from 57.6% to 99%, indicating a high susceptibility of L. sericata to attack by C. albiceps.…”

PALAVRAS-CHAVE: Comportamento larval, mosca-varejeira, competiçãoABSTRACT -The pattern of larval interaction in blowfl ies confi ned with Chrysomya albiceps Wied. and C. rufi facies Maquart can be changed in response to the predatory behaviour of the two species to a contest-type process instead of the scramble competition that usually occurs in blowfl ies. Facultative predation is a frequent behaviour in C. albiceps and C. rufi facies that occurs as an alternative food source during the larval stage. In this study, we investigated the dynamics of intraguild predation by C. albiceps on other fl y species in order to analyse interspecifi c and intraspecifi c survival in C. albiceps, C. megacephala and C. macellaria Fabricius. The experimental design of the study allowed us to evaluate how factors such as species, density and abundance of food infl uenced the survival of the calliphorid species. When C. albiceps was confi ned with C. megacephala or C. macellaria, only adults of C. albiceps survived at different larval densities and abundance of food. In addition, the survival of C. albiceps was higher in two-species experiments when compared to single species experiments. The implications of these results for the dynamics of C. albiceps were discussed.

“…Em experimentos de dispersão com espécies da família Calliphoridae, o número de larvas que dispersam também diminuiu com o aumento da distância (Greenberg 1990, Godoy et al 1995, 1996, de Andrade et al 2002. Nas maiores distâncias, compreendidas entre 40,1 cm e 50 cm, foram encontrados apenas 29 indivíduos, sendo que somente um atingiu a distância máxima possível durante o processo de dispersão (50 cm).…”

-Muscina stabulans (Fallén) is a synanthropic fl y commonly found in decomposing animal matter. Once food resources are exhausted, larvae will disperse in search for a suitable place to pupariate or for an additional source of food. The behavior of propagation of postfeeding L3 larvae was studied by analyzing the distance of propagation, the depth of pupariation site, the pupal weight and sex ratio using a 50 cm circular arena divided in four quadrants, and fi lled with a 10 cm thick layer of humid sawdust. The total of 70.9% of the larvae pupariate up to 20 cm away from the arena's center, with 41.8% of them from 2.1 cm to 4.0 cm deep. Pupae that did not yield adults were lighter, and were originated by larvae that moved longer away and dug deeper to pupariate in relation to those from which adults emerged.
