昆虫，特别是丽蝇（双翅目：丽蝇科），往往是第一个到达犯罪现场，并提供关键信息，包括死后时间间隔和尸体是否已从其原来的位置，以及其他有用的信息。历史告诉我们，昆虫与死亡的联系早在事件记录中就被认识到了（Greenberg和Kunich 2005; Benecke 2001）。随着我们对这一联系的不断了解，法医昆虫学领域在不同的情况、环境以及新方法的结合方面不断取得戏剧性的进展，例如本书中提到的那些进展。虽然用于确定死后间隔（PMI）的方法，如幼虫年龄测定和节肢动物演替，不断被使用，并进一步研究吸引苍蝇到身体的机制还没有得到充分的探讨。据充分记载，雌蝇在死亡后不久会在伤口或自然孔口附近产卵，以便幼虫可以在潮湿区域发育（Smith 1986;安德森2001）。然而，确切地确定是什么吸引昆虫到腐烂的尸体上并引起行为反应，如交配和产卵（产卵），仍然没有被确定。
Insects, specifically blowflies (Diptera: Calliphoridae), are often the first to arrive at the scene of a crime and provide crucial information including post mortem interval and whether the body has been moved from its original location, amongst other useful information. History tells us that insects’ association with death was recognised as early as documentation of events could be made (Greenberg and Kunich 2005; Benecke 2001). As we continue to understand this link dramatic advances, such as those mentioned throughout this book, are continually being made in the field of Forensic Entomology in relation to different situations, environments, as well as the incorporation of new approaches. While the methods used to determine the post-mortem interval (PMI), such as larval age determination and arthropod succession, are continually being used and further investigated the mechanism which attracts the flies to the body has not been fully explored. It is well documented that female flies will lay eggs near wounds or natural orifices soon after death so that the larvae may develop in a moist area (Smith 1986; Anderson 2001). However, determining exactly what attracts insects to a decomposing body and cause behavioural responses such as mating and laying eggs (oviposition), has still not been identified.
