沈阳地区室内常见尸食性蚤蝇幼期识别

Identification of immature stages of carrion-breeding phorid flies indoors in Shenyang

利用尸食性蝇类发育生物学推断死后间隔时间的前提是对其幼期种属的准确鉴定。本文对沈阳地区室内常见的4种尸食性蚤蝇幼期的主要形态特征进行了描述。结果表明:根据其口器、体壁突起、气门和呼吸角等特征不仅可以区分虫龄,还可以鉴别4种蚤蝇。

The accurate identification of the fly larva or puparium to species is the premise when the development biology of carrion-breeding flies is used to estimate post-mortem interval. This paper presented the description of the main morphological features of immature stages of four most common carrion-breeding phorid flies indoors in Shenyang. The results show that the features, cephalopharyngeal skeleton, tubercles of integument, spiracles and respiratory horns, were not only used to differentiate the three instars, but also identify the four phorid flies.
