摘　　要：采用数学生态学定量研究的方法，对家蝇实验种群的繁衍动力学进行了研究，求出了各项动力学参数值：净增殖率Ｒｏ为８０４６４５０；平均世代周期长Ｔ为２８７７３４ｄ；无限增殖的增长能力ｒｃ为０２５２５；有限增长能力λ为１２６１８；瞬时出生率ｂ为０９５３４％；瞬时死亡率ｄ为０７２０９％；种群增加一倍所需时间ｔ为２９８１１ｄ；在种群的稳定年龄组配中，成蝇前期占９４６２４０％；成蝇期占５３７６０％。Under the most suitable comprehensive experimental conditions,the scientific research on the experimental population of Musca domestica was carried out by the method of quantitative study.The results were as follows:the net reproduction rate( R o) was 804.645 0,the mean period of a generation ( T ) 28.773 4 d,the infinitesimal rate of increase ( r c) 0.232 5,the finite rate of increase( λ ) 1.261 8,the instantaneous birth rate ( b ) 0.953 4,the instantaneous death rate( d ) was 0.720 9 and the necessary time of increasing one time ( t ) 2.981 1 d.Out of the stable age distribution,total immature stages was 94.624 0% and total adults 5.376 0%.The results provided the scientific basis for exploitation and elimination of Musca domestica .
