“…O comportamento de dispersão larval pós-alimentar e o conseqüente padrão de distribuição espacial das pupas nos sítios de pupação podem ter implicações na maior ou menor suscetibilidade das mesmas ao ataque de predadores e parasitóides, em populações de ambientes naturais (LEGNER, 1977). Em ambiente natural, as larvas de L. cuprina e de outras espécies de califorídeos, como C. megacephala, podem atingir profundidades e distâncias variadas para pupação, dependendo do tipo de substrato e nível de compactação do mesmo a partir do centro de dispersão .…”

ABSTRACT. Postfeeding radial larval dispersion in Lucilia cuprina (Diptera, Calliphoridae): depth, weight and distance of burying for pupation. Blowflies utilize discrete and ephemeral sites for breeding and larval nutrition. After the exhaustion of food, the larvae begin dispersing to search for sites to pupate or for additional food source, process referred as postfeeding larval dispersal. Some aspects of this process were investigated in Lucilia cuprina (Wiedemann, 1830), utilizing a circular arena to permit the radial dispersion of larvae from the food source in the center. To determine the localization of each pupa, the arena was split into 72 equal sectors from the center. For each pupa, distance from the center of arena, weight and depth were determined. Statistical tests were performed to verify the relation among weight, depth and distance of burying for pupation. It was verified that the larvae that disperse farthest are those with lowest weights. The majority of individuals reached the depth of burying for pupation between 7 and 18 cm. The study of this process of dispersion can be utilized in the estimation of postmortem interval (PMI) for human corpses in medico-criminal investigations.

“…O comportamento de dispersão larval pós-alimentar e o conseqüente padrão de distribuição espacial das pupas nos Distribuição dos machos Distribuição das fêmeas sítios de pupação podem ter implicações na maior ou menor susceptibilidade das mesmas ao ataque de predadores e parasitóides, em populações de ambientes naturais (LEGNER 1977;PESCHKE et al 1987). É interessante citar que esses estudos de dispersão podem ter importantes implicações para investigações médico-criminais, porque a presença de larvas e pupas nas circunvizinhanças de ou em cadáveres humanos pode auxiliar na estimativa do intervalo de tempo entre a morte e a descoberta do cadáver, referido como intervalo pós-morte (IPM).…”

ABSTRACT. Study of postfeeding larval radial dispersal in Chrysomya megacephala (Fabricius) (Diptera, Calliphoridae). Blowflies utilize discrete and ephemeral sites for breeding and larval nutrition. After the exhaustion of food, the larvae begin dispersing to search for sites to pupate or to additional food source, process referred as postfeeding larval dispersal. Some of the most important aspects of this process were investigated in Chrysomya megacephala, utilizing a circular arena to permit the radial dispersion of larvae from the center. To determinate the localization of each pupa, the arena was split in 72 equal sectors from the center. For each pupa, distance from the center of arena, weight and depth were determined. Statistical tests were performed to verify the relation among weight, depth and distance of burying for pupation. It was verified that the larvae that disperse farther are those with higher weights. The majority of individuals reached the depth of burying for pupation between 7 and 18 cm. The study of this process of dispersion can be utilized in the estimation of postmortem interval (PMI) for human corpses in medico-criminal investigations.

“…During this phase, the blowfly larvae may be at risk of predation, parasitation and desiccation (Legner 1977, Peschke et al 1987. In two previous studies, Godoy et al (1995Godoy et al ( , 1996 investigated the dispersal of post-feeding larvae of Chrysomya megacephala (Fabricius), C. putoria (Wiedemann) and Cochliomyia macellaria (Fabricius).…”
