Decomposed flesh as a vitellogenic protein source for the forensically important Lucilia sericata (Diptera: Calliphoridae).

For the carrion-feeding blow flies, a common source of vitellogenic protein are the carcasses that also serve as larval substrates. This attraction continues well after the blow flies have ceased to oviposit on the carrion, and it has been assumed that a decomposed cadaver remains a suitable source for vitellogenic protein; however, this assumption has never been tested. To test this hypothesis, blow flies (Lucilia sericata Meigen) were supplied with either fresh or decomposed beef liver as protein sources for vitellogenesis for 5 d.

Maggot development during morgue storage and its effect on estimating the post-mortem interval.

When insect evidence is obtained during autopsy, forensic entomologists make decisions regarding the effects of low-temperature (-1 degrees C to 4 degrees C) storage of the body and associated insects when estimating the post-mortem interval (PMI). To determine the effects of storage in a morgue cooler on the temperature of maggot masses, temperatures inside and outside of body bags containing a human cadaver and porcine cadavers (seven replicates) were measured during storage. Temperatures remained significantly higher (p<0.
