中文摘要: 置家兔尸体于室外空地进行观察,研究春季西安地区家兔尸体上昆虫群落的组成及演替规律。结果表明西安地区春季常见的尸食性的昆虫包括3目11科16种,其中双翅目的巨尾阿丽蝇Aldrichina grahami、鞘翅目一种阎甲Margarinotus sp.为优势种。尸体上昆虫群落的演替有明显的时间规律可循,昆虫类群的出现时间与尸体的腐败阶段有明确的对应关系,可以为法医科学中推测死亡时间提供依据。
英文摘要: The succession of sarcosaphagous insects on domestic rabbit carcasses in Xi'an area was observed. Sarcosaphagous insects belonging to 16 species, 11 families and 3 orders were identified, of which Aldrichina grahami and Margarinotus sp. were the dominant species. Community succession had two obvious stages over the course of carcasses′ decay. Changes in community composition over time occur in a predictable sequence that can provide the basis for determining time since death.
