目的观察杭州和广州两地常见嗜尸性蝇类发育历期,为法医学应用昆虫学知识推断死亡时间提供基础数据。方法于杭州和广州两个地区,采集丝光绿蝇(Lucilia sericata Meigen)、大头金蝇(Chrysomyia megacephala Fabrious)、绯颜裸金蝇(Achoetandrus rufifacies Macquart)、棕尾别麻蝇(Boettcherisca peregrina Robinean-Desvoidy)、家蝇(Musca domestica Linnaeus)和巨尾阿丽蝇(Aldrichina grahami Aldrichnia)共6种常见蝇种的卵,采用不同温度下恒温饲养及密集取样方法,观察分析6种常见蝇种的发育历期时间。结果广州地区观察的丝光绿蝇、大头金蝇和绯颜裸金蝇,总体上在低温下发育历期较长,高温下较短,其中大头金蝇和绯颜裸金蝇耐寒能力较差。杭州地区观察的丝光绿蝇、大头金蝇、棕尾别麻蝇、家蝇和巨尾阿丽蝇,总体发育历期总趋势与广州相似,但较广州地区表现出更好的耐寒性。结论本文所获数据可为相关地区实际案例的侦破提供依据或参考。
Objective To observe the developmental stages of common sarcocarpous flies in Hangzhou and Guangzhou, and provide basic data for forensic use of entomological knowledge to infer the time of death. Methods Lucilia sericata Meigen, Chrysomyia megacephala Fabrious, Achoetandrus rufifacies Macquart, Boettcherisca peregrina Robinean-Desvoidy were collected from Hangzhou and Guangzhou. , Musca domestica Linnaeus and Aldrichina grahami Aldrichnia were collected. The eggs of six species of common fly were cultured at different temperatures and intensive sampling. The developmental stages of six species of common fly were observed and analyzed. time. Results In the Guangzhou area, the green flies, the golden flies and the fescue naked flies were observed in Guangzhou area. Generally, their developmental duration was longer at low temperature and shorter at high temperature. In Hangzhou area, the general trend of development was similar to that of Guangzhou, but showed a better resistance to cold than that of Guangzhou in the light green flies, gold flies, brown flies, house flies and giant tail flies. Conclusion The data obtained in this paper may provide the basis or reference for the detection of actual cases in the relevant areas.
