摘　　要：[目的]研究广东栅蚤蝇[Diplonevra peregrina(Wiedemann)]在室内自然变温条件下的发育规律。[方法]在室内自然变温条件下研究广东栅蚤蝇的发育速度和有效积温。[结果]室内自然变温条件下广东栅蚤蝇卵、幼虫及蛹的发育起点温度分别为(14.78±1.25)、(15.88±0.90)和(16.04±0.20)℃,有效积温分别为(176.24±19.52)、(1 571.95±158.07)和(3 516.41±100.46)h×℃,确立了2个有效积温与幼虫体长的线性回归方程:Y1=0.862+0.848X1、Y2=27.604-1.460X2。[结论]在室内自然变温条件下用积温法则建立起的广东栅蚤蝇发育数学模型可应用于法医学死亡时间推断。Objective] To investigate development law of Diplonevra peregrina （Wiedemann） under indoor natural temperatures.[Method] Rate of development and total effective accumulated temprature of D.peregrina were studied under indoor natural temperature.[ Result] De-velopmental threshold temperature of eggs, larvae and pupae were （14.78 ±1.25）, （15.88 ±0.90） and （16.04 ±0.20） ℃, respec-tively, and effective accumulated temperature were （176.24 ±19.52）,（1 571.95 ±158.07） and （3 516.41 ±100.460） h·℃, respec-tively.Two equation of linear regression （Y1 =0.862＋0.848X1, Y2 =27.604-1.460X2） were established between the total effective tem-perature and the body length of larvae.[ Conclusion] It can be used to estimate the time of death in forensic medicine practice depending on the mathematical model from the effective temperature under indoor natural temperature.
