摘要： 目的 积累一些嗜尸性蝇类生活史的资料及群落组成的季节性变动规律。 方法 采用动物尸体作诱饵，分别对自然飞到诱饵上繁殖生长的8种嗜尸性蝇类的生活史及群落组成的季节性变动规律进行观察研究。 结果 夏季高温时段蝇类群落组成物种较为丰富，冬季低温时段蝇类种群较为单一。常见8种嗜尸性蝇类虫态经历时间在气温高时较短，气温低时较长。 结论 嗜尸性蝇类生活史及群落组成的季节性变动规律可为推测死亡时间提供依据。

Abstract: Objective To study the nature of necrophagous flies, their developmental cycle and seasonal variation. Methods Animal corpse was used to be baiting. Eight kinds of necrophagous flies on their developmental cycle and the pattern of seasonal variation were analyzed. Results The community of necrophagous flies at high temperature in summer were more abundant than at low temperature in winter. Eight necrophagous flies through longer time at high temperature during every state than at low temperature. Conclusion  The life cycle and seasonal variation pattern of necrophagous flies could be used to estimate the time of death in practical cases.
