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8046450;平均世代周期长T为287734d;无限增殖的增长能力rc为02525;有限增长能力λ为12618;瞬时出生率b为09534%;瞬时死亡率d为07209%;种群增加一倍所需时间t为29811d;在种群的稳定年龄组配中,成蝇前期占946240%;成蝇期占53760%。结果为家蝇的防治和利用提供了科学的理论依据
Based on the quantitative study of mathematical ecology, the dynamics of propagation of housefly experimental population was studied, and the kinetic parameters were obtained: the net growth rate Ro was 8046450; the average generation period T was 287734d ; Unlimited growth ability rc was 0 2525; limited growth capacity λ 1 2618; instantaneous birth rate b was 0 9534%; instantaneous mortality rate d was 0 7209%; population doubling the time t is 2 9811d; in the stable population age group, the pre-adult fly accounted for 946240%; adult fly accounted for 53760%. The results provide a scientific theoretical basis for the prevention and control of housefly
