Abstract
The green bottle blow fly Lucilia sericata is recognized as being among the first wave of the faunal succession on human cadavers. Thus, it is used to estimate the postmortem interval (PM!). The nutritional intake of larvae is likely to vary subject to the part of a corpse on which they are feeding. A study was therefore conducted to investigate the effect for the type of food substrate on larval growth in this species. Larvae were reared on cow liver, brain, heart, lung, kidney, intestine or minced meat Results showed significant differences in the duration of the feeding, postfeeding larval, and pupal stages from different substrata (F = 42.43; 74.71 and 655.71; P < 0.0001, respectively). Larval growth measured as length varied significantly between different tissues (F = 3.56; P <0.05). Larvae that were reared on heart were smaller than those reared on other tissues. Also, there was a significant effect for the type of tissue on the adult size of males (F = 2.41, P < 0.05) and females (F = 2.85, P < 0.05). These results may have important implications for forensic entomologists, since initial infestations commonly occur in wounds or in the cranial area. Therefore, the position at which larvae have been feeding on a body will be a crucial observation at a crime scene and is very important in PMI estimation.
