卵、幼虫的发育行为。研究了10种不同温度条件下蝇类丝光Lucilia sericata （Meigen）的蛹。这些研究的数据被用来构建等长图。在这张图中，从孵化到摄食高峰的时间是根据温度绘制的，每条线代表不同温度下相同的幼虫长度。如果温度大致恒定，就像在室内发现尸体的情况一样，只要蛆还没有进入迁徙阶段，就可以立即从它的长度判断出它的年龄。在温度可变的情况下，可以在记录的最高和最低温度下测量的幼虫长度切断图表的点之间估计出年龄范围。同样，如果从现场找到处于迁徙期的蛆虫或蛹或蛹蛹，则应使用代表从产卵到羽化的所有形态阶段的同模图。即使对于没有经验的研究者来说，等omega - alen-和同型酚图也可以帮助快速和更精确地估计死亡时间。此外，我们的研究结果与其他研究者的研究结果有所不同，表明在不同的动物地理区域，全北极丝光苍蝇的热行为是不同的。(C) 2001年由爱思唯尔科学爱尔兰有限公司出版
Developmental behavior of eggs, larva. and pupa of the blowfly species Lucilia sericata (Meigen) were studied under 10 different temperature regimes. Data from these studies were used to construct the isomegalen-diagram. In this diagram, time from hatching to peakfeeding is plotted against temperature, each line representing identical larval length at various temperatures. If the temperature is roughly constant, as is the case with corpses found indoors, the age of the maggot can be read off instantly from its length, provided that the maggot has not entered the migratory phase. Where temperature is variable, an age range can be estimated between the points where the measured larval length cuts the graph at the maximum and minimum temperatures recorded. Equally, the isomorphen-diagram representing all morphological stages from oviposition to eclosion should be used, if maggots in the migratory phase or pupae or puparia are recovered from the scene. The isomegalen- and the isomorphen-diagrams could facilitate a quick and more precise estimate of the postmortem interval even for the inexperienced investigator. In addition, our results vary from those of other investigators, suggesting a different thermal behavior of the holarctic blowfly L. sericata in various zoogeographic regions.
