Insect behavior and control techniques

Insects pledged to the corpses are increasingly used for the postmortem interval determining. The aim of this work is to study the biological parameters of Lucilia sericata colonizing the liver of mammals in the Guinean zone of Ivory Coast for use in forensic. The study of the biological parameters revealed that L. sericata is an holometabol insect with three larval stages in the developmental cycle and a pupal stage. A female of L. sericata has laid on average of 1438.86 ± 47.8 eggs on pig liver, while that on beef liver it laid on average 1296.8 ± 62.45 eggs. The duration of the developmental cycle of L. sericataon the B. indicus’liver of and S. scrofa domesticus was respectively 13.94 ± 0.24 days and 13.21 ± 0.22 days at a temperature of 26.85 ± 0.90°C and a relative humidity of 88.7 ± 1.3%. In the semi-environmental condition, the emergence rate was higher on the pig’s liver. The length of the development cycle was short on the pig’s liver and long on that of beef. The sex-ratio was respectivily 0.86 ± 0.05 and 0.76 ± 0.02 on the of pig’s liver and beef’s liver. The male flies lived less longer than females.
