Effects of morphine on Lucilia sericata growth accumulated degree hour and deduction of decedent postmortem interval

Abstract

Abstract: To investigate the effects of morphine on the growth of Lucilia sericata larvae or pupae,and the deduction of decedent postmortem interval(PMI) based on it,rabbits were injected with different doses morphine hydrochloride and killed,and their muscles were used to feed the newly-hatched L.sericata larvae.The results showed that after fed with the muscles,the larvae length and pupae weight under natural conditions were larger than those of the control to different extents,and their growth accumulated degree hour(ADH) was decreased.Within the range of test doses(4.7～18.8 mg·kg^-1),morphine could promote the growth of Lucilia sericata larvae and pupae.This promotion effect of morphine could result in a maximum deduction deviation for about 80 h when the growth ADH of L.sericata larvae or pupae was used to deduce the decedent PMI.
