Zusammenfassung

Lucilia sericata ist unter den nekrophagen Insekten, die den menschlichen Leichnam besiedeln, bei der Eingrenzung der Todeszeit von großer forensischer Bedeutung. In der vorliegenden Arbeit wurde untersucht, welchen Einfluss Methadon auf die Entwicklung dieser Fliegenart hat. Es konnte eine signifikante Beschleunigung des Wachstums der Larven zwischen dem 3. und 5. Tag bei methadonhaltigem Substrat festgestellt werden. Die Gesamtentwicklungsdauer im Larven- und Puppenstadium war bei einer therapeutischen (Methadonsubstitution) und einer toxischen Methadonkonzentration gegenüber der Kontrollgruppe um bis zu 15 h verkürzt. Diese Ergebnisse sollten bei entsprechenden forensisch-entomologischen Begutachtungsfällen Berücksichtigung finden.

Abstract

The greenbottle fly Lucilia sericata is an insect of great forensic interest for estimating the postmortem interval. The present study investigated the influence of methadone on the development of Lucilia sericata larvae. The results of the study showed a significant acceleration of larval development between day 3 and 5 when methadone is present in the food source. The total development times where shortened by up to 15 h in the group with therapeutic and toxic methadone concentrations. These results should be considered when undertaking forensic entomological examinations.
