摘　　要：用盐酸吗啡注射家兔,处死后用家兔的肌肉组织饲养丝光绿蝇(Lucilia sericata)初孵幼虫,研究吗啡对丝光绿蝇幼虫和蛹生长发育的影响及其在法医学中推断死者死亡时间方面的应用.结果表明,在自然条件下,取食处理组兔肉的丝光绿蝇幼虫的体长和蛹的重量在不同程度上大于对照组;处理组发育积温均比对照组减少.在实验的剂量范围内(4.7～18.8 mg·kg-1),吗啡可促进丝光绿蝇幼虫和蛹的生长发育.根据幼虫或蛹的发育积温推断死者死亡时间,吗啡的这种影响可使推断值产生的最大偏差达80 h左右.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.
