Les larves de diptères nécrophages en entomologie médico-légale : une histoire de température
Prix médecine/sciences
Thermoregulation behavior in necrophagous dipteran larvae
Univ. Lille, CHU de Lille EA 7367 – UTML – unité de taphonomie médico-légale, 1, place de Verdun, 59045 Lille, France
L’entomologie médico-légale est l’utilisation des insectes afin de calculer l’intervalle post-mortem (temps écoulé entre la découverte d’un corps et la mort réelle de l’individu). Connaître la biologie, la physiologie et le comportement de ces insectes sur l’écosystème représenté par le cadavre est d’une importance primordiale pour améliorer les expertises entomologiques. C’est sur quoi se focalise l’unité de taphonomie médico-légale, unique équipe de recherche en France experte sur ce sujet.
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.
