The present studyrndemonstrated the detection of Ketamine hydrochloride from the immature stagesrnof Chrysomya megacephala (Fab.) and observation of its effect on therndevelopment of this fly. Larvae of C. megacephala were reared on ratrntissues administered the half lethal, lethal and twice lethal dosages of Ketaminernhydrochloride antemortem. Development of immature stages was estimated on thernbasis of various parameters like weight, length, width, time of adult emergencernand survival rate. Results indicate that an estimate of the postmortem intervalrnbased on the normal development of C. megacephala could have an error ofrnup to 60-92 hours if based on the age of the larva, and 92-172 hours if basedrnon the age of the pupa sampled from decomposing remains. Larvae of C.rnmegacephala feeding upon control treatment demonstrated higher survivalrnrate, pupariation and eclosion success as compared to larvae exposed to the different dosages of Ketamine hydrochloride. The presence of Ketaminernhydrochloride could be detected through Gas Chromatography (GC) in all rat samples and in almost all dipteral samples in the experiment.
