Chrysomya megacephala and C. rufifacies are globally predominant species of blowflies that are amongst the primary colonisers of decomposing carcasses. The development of blowflies has been studied extensively to estimate the minimum postmortem interval (PMI). This article evaluates the effect of aluminium phosphide (AlP) on the larval morphometry and life cycles of C. megacephala and C. rufifacies. The rabbits were given different dosages of AlP and their livers were excised to rear C. megacephala and C. rufifacies. Through multiple-regression analysis, we assessed the overall impact of varying dosages of AlP on larvae of both species. AlP accelerated development until pupation, whilst the time until emergence remained the same. At higher concentrations, AlP had a positive effect on the development of these species. Since both species are abundant, forensic entomology studies examining the effect of AlP on morphometry and developmental stages would provide valuable information to investigators assessing PMI.
大头金蝇和红头丽蝇是全球主要的麻蝇物种，是尸体分解的主要殖民者之一。麻蝇的发育过程已经被广泛研究，以估计最小死后间隔时间（PMI）。本文评估了磷化铝（AlP）对大头金蝇和红头丽蝇幼虫形态和生命周期的影响。给兔子服用不同剂量的 AlP，并切除其肝脏以饲养大头金蝇和红头丽蝇。通过多元回归分析，我们评估了 AlP 不同剂量对两种物种幼虫的总体影响。AlP 加速了发育直到蛹化，而出现的时间保持不变。在较高浓度下，AlP 对这些物种的发育有积极影响。由于这两个物种都很丰富，法医昆虫学研究检查 AlP 对形态和发育阶段的影响将为评估 PMI 的调查人员提供有价值的信息。
