Larval-mass effect: Characterisation of heat emission by necrophageous blowflies (Diptera: Calliphoridae) larval aggregates.
TLDR
Results indicate that heat emission can occur even with "small" masses if they are composed of high number of second stage larvae, and that optimum ambient-temperature values ranging between 22°C and 25°C produce maximal heat-emission per larva. Expand
Effects of morphine in decomposing bodies on the development of Lucilia sericata (Diptera: Calliphoridae).
TLDR
Results of this study show that an underestimation of the postmortem interval of 24 h is possible if the presence of morphine in tissues is not considered, demonstrating the necessity of considering the possible effects of drugs in tissues on insect growth rates when estimating the post autopsy interval using entomological techniques. Expand
Necrophilous insect succession on rabbit carrion in sand dune habitats in northern France.
TLDR
A significant feature in this study was the delay in initial oviposition by flies during 1996, which demonstrates the need for caution in estimation of postmortem interval by entomological techniques in early spring. Expand
Morphine extraction in necrophagous insects remains for determining ante-mortem opiate intoxication.
TLDR
Remains of necrophagous insects, particularly puparial cases, are often preserved for a long time, and consequently can serve as late alternative specimens for toxicological analysis when suitable tissues are not available. Expand
Entomofauna of buried bodies in northern France
TLDR
This study concerns insects sampled on 22 exhumed cadavers in the Lille area, where three species were regularly found because of their preference for underground environments or closed environments. Expand
Determination of drug levels in larvae of Lucilia sericata (Diptera: Calliphoridae) reared on rabbit carcasses containing morphine.
TLDR
Concentrations of morphine in larvae reared on rabbit carcasses containing morphine were 30 to 100 times lower than the concentrations found in the tissues, and correlations were found between administered dosages, tissue concentrations and younger larvae, prepuparial larvae or puparia. Expand
Immunohistochemical contribution to the study of morphine metabolism in Calliphoridae larvae and implications in forensic entomotoxicology.
TLDR
The possibilities of analyzing empty pupariae when suitable tissues or living necrophagous insects are absent are pointed out and morphine accumulation inside the cuticle of Diptera larvae during their development is found. Expand
Flies eggs: a new method for the estimation of short-term post-mortem interval?
TLDR
Three modeling methods were used to estimate the time for laying of Lucilia sericata eggs (Diptera, Calliphoridae), and consequently this determines the time of death, as this species lays immediately after death under favorable conditions. Expand
Determination of drug levels in two species of necrophagous Coleoptera reared on substrates containing morphine.
TLDR
The potential for use of necrophagous Coleoptera, as well as Diptera larvae, as alternate specimens for toxicological analyses is demonstrated and concentrations correlated with cadaveric tissue concentrations during larval stages and to a lesser extent in the adult stage are demonstrated. Expand
Development Time Variability: Adaptation of RegnieresMethod to the Intrinsic Variability of Belgian Lucilia Sericata(Diptera, Calliphoridae) Population
TLDR
A simulation method was developed by adapting the Regniere’s method that allowed accurate prediction of the emergence profile of L. sericata at constant temperature in the linear portion of the development curve and could increase the reliability of the conclusions of an entomological Post Mortem Interval (PMI) estimation.
