摘　　要：家蝇蛆系完全变态昆虫家蝇(Musca domestica L.)的幼虫,在我国分布极其普遍,具有易于孵育,饲养成本低,可集约化大规模养殖之特性。蝇蛆油GC-MS分析结果表明,蝇蛆油脂不饱和脂肪酸含量为56.79%,其中单不饱和脂肪酸占42.58%,多不饱和脂肪酸占14.21%。文中以酸催化酯化降酸预处理和碱催化酯交换两步法利用家蝇蛆油合成生物柴油,在酯交换中,反应温度为50℃、醇油比为5∶1、催化剂质量为总质量的1.25%、反应时间为45 min的条件下,得到了脂肪酸甲酯含量为85.46%的生物柴油。采用家蝇蝇蛆合成生物柴油作为生物能源的新原料与新途径,具有很高的工业适用性与可操作性。Housefly larva （Musca domestica L.） is a common complete metamorphosis insect whichis widely distributed in China. It is easy to hatched with a low cost and has been Scale breeding.The analysis of housefly larvae oil by GC-MS showed that the unsaturated fatty acid was 56.79%,including 42.58% monounsaturated fatty acid and 14.21% polyunsaturated fatty acid. In this study,acid esterification followed and alkaline transesterification were used to preparation of biodiesel .The optimized conditions included a reaction temperature of 50 ~C, a 5：1 methanol to oil molar ra-tion, 1.25% catalyst and a reaction time of 45 rain. Under these conditions, the yield of fatty acidmethyl esters was 85.46%. Preparation of Biodiesel with housefly larva oil has showed a high in-dustrial applicability and operability as a new material and approach.
