Extraction and Identification of Hydrocarbon Compounds of some species of metallic blow flies (Diptera : Calliphoridae) .

Abstract

Extraction and Identification of hydrocarbon compounds from six species of metallic blow flies ; Chrysomya megacephala , Ch . albiceps , Calliphora vicina, C. livida , C. terreanova and lucilia sericata , were determind by using GC- Mass technique. The results show that alkenes whith hydrocarbon chain between (C12-C36) with apredominant of the leniar alkanes with highest percentage of 16.53 % for Tricosane compound in Ch.megacephala , whereas the loest percentage was 0.29% for Nonacosane in Calliphora terreanovae , the leniar alkenes with lowest percentage 6.9% in Ch. megacephala . The latter species had highest number of quannititae of hydrocarbons , however the species C. livida have lowest numbers. The species C.vicina and C.livida which the hydrocarbons content was identical with a little and trace variation ,thus a futher investigation regarding their classification is needed .
