| 摘 要： | 蝇蛆体长是判断死后间隔时间最常应用的指标.为了准确测量幼虫的体长,本文提出利用Olympus三维重构图像处理系统进行活体测量的新方法,在20℃和28℃两个恒温下,对蛆症异蚤蝇Megaselia scalaris(Loew)幼虫体长变化进行了观察、测量.结果表明:该方法简便、易行,适于尸食性蚤蝇幼虫体长的测量.对两个恒温下体长随时间的变化情况进行了模拟,模拟效果较好.

| Abstract: | The body length of maggots is a indicator often used for the post-mortem interval estimation. In order to accurately measure the larvae body length, a new method of living measurement is proposed using Olympus 3D reconstruction and image processing system. Under two constant temperature conditions of 20 ~C and 28 ~C, the length changes of Megaselia scalaris （Loew） larvae were observed and measured. The results show that the method is simple, and easy to operate, and suitable for the measurement of carrion-breeding phorid flies larvae length. The dependence of the larval change in length on two temperature conditions can be well simulated with linear regression. |
