Composition and life cycles of necrophagous flies infesting wrapped and unwrapped rabbit carcasses in Johor for forensic applications

In forensic cases, corpses are frequently discovered wrapped in some material, probably as a means for disguising, as well as enabling easier handling and preventing evidence transfer. The use of such wrapping materials may affect insect colonization patterns, which in turn causing erroneous estimat...
