摘要对自由生长的年龄结构种群进行了模拟，并通过雄性不育释放来控制其生长。平衡种群产生关键的雄性不育排泄率，这将使种群保持平衡。这里表明，这些速率可能不同于阻止不断增长的人口并使其达到平衡所需的释放速率。建立了该种群的计算机模拟，并进行了参数敏感性分析，得出了雄性所需的育性释放率、雌性成虫交配延迟、幼虫净存活率、3条成虫存活曲线、幼虫在幼虫阶段所花费的时间和总寿命的影响。成虫存活曲线对种群消除所需的不育释放率影响最大。还利用实验室菌株的存活率和生育力数据确定了头型脑膜炎(Wiedemann)所需的释放率。讨论了上述情况下的超泛率和释放率的概念，并将其量化。
ABSTRACT A freely-growing age-structured population was modeled for growth and control by sterile male releases. Equilibrium populations yield critical sterile male release rates that would hold the population at equilibrium. It is shown here that these rates may be different from the release rates required to stop a growing population and bring it to an equilibrium. A computer simulation was constructed of this population and a parameter sensitivity analysis graphed the effects on the required sterile male release rate of fertility, mating delay in adult females, net juvenile survivorship, three adult survivorship curves, the time spent in the juvenile stages, and total life span. The adult survivorship curves had the greatest effect on the required sterile release rate for population elimination. The required release rate was also determined for Ceratitis capitata (Wiedemann) using survivorship and fertility data from a laboratory strain. The concepts of over-flooding ratio and release ratio were discussed and quantified for the cases above.
