Flies eggs: a new method for the estimation of short-term post-mortem interval?
Three modeling methods were used to estimate the time for laying of Lucilia sericata eggs (Diptera, Calliphoridae) after measurements of hatching times at several constant temperatures. These models were tested first under controlled conditions with 19 profiles of fluctuating temperatures, and on the other hand under field conditions on mice. All three models were allowed to determine the time of laying within a period of about 2h, and consequently this determines the time of death, as this species lays immediately after death under favorable conditions. Rearing of eggs sampled on a corpse may therefore contribute to the determination of a short post-mortem interval (PMI).
