[Thermoregulation behavior in necrophagous dipteran larvae]

Abstract

The forensic entomology is the use of insects to date the death. The forensic expert assessment is based on the development of necrophagous insects which are growing on the cadaver, to calculate their age and then estimate the Post-Mortem Interval. This development depends on a number of parameters like temperature, species or behavior. The French Forensic Taphonomy unit, the only expert team on the subject in France, works on the biology, physiology and ethology of the necrophagous insects. Their works are focused on thermoregulation behavior and thermal preferendum of maggot masses, aggregation phenomenon and social interaction or on food intake. These works are particularly of interest to understand the pre-social parameters and evolution strategies. More importantly, their aim is to better understand the development of necrophagous insects and, in fine, to improve the forensic expert assessment.
