  • Title: The effects of larval crowding and food type on the size and development of the blowfly, Calliphora vomitoria.
    Author: Ireland S, Turner B.
    Journal: Forensic Sci Int; 2006 Jun 02; 159(2-3):175-81. PubMed ID: 16221536.
    Abstract:
    The use of entomological evidence in the estimation of the post mortem interval (PMI) often depends on the size and developmental stage of blowfly larvae collected from a corpse. Therefore, factors which can have an effect on the larval size and growth rate can have implications for reliable PMI determinations. This study explores the competitive effects of larval overcrowding on Calliphora vomitoria reared on three different pig tissues--liver, brain and muscle. The competitive feeding environment within the more crowded larval cultures resulted in increased development rates and the production of undersized larvae and adults. Variation in the extent of these effects was observed on each of the three body tissues, highlighting the importance of documenting the positions from which entomological evidence is recovered from a corpse.
