983年7、8月和1984年7、8月,在郑州市郊进行了中华按蚊自然种群动力学的调查研究。以获得的各项数据,引用数学模型,计算出各年该蚊第六、七、八世代的净增殖率和有关种群参数值。与该蚊实验种群相应参数做比较,除12天后成蚊存活百分比和平均世代周期长相近外、其余各参数值均明显偏低、说明野外自然因素和天敌对中华按蚊所构成的环境阻力是相当大的。该蚊自然种群动力学参数值的求出对防蚊灭疟策略的制订具有重要意义。该文首次提出求最后产卵日期的数学模型。
In July and August in 983 and July and August in 1984, the population dynamics of Anopheles sinensis in the suburbs of Zhengzhou were investigated. Based on the data obtained, the mathematical model was used to calculate the net reproduction rate and related population parameter values of the sixth, seventh and eighth generations of the mosquito in each year. Compared with the corresponding parameters of the experimental mosquito population, the values of other parameters were significantly lower than those of the other mosquitoes after 12 days, indicating that the environmental resistance of natural factors and natural enemies to Anopheles sinensis was Quite big. The mosquito natural population dynamics parameter value of the anti-mosquito malaria strategy to formulate is of great significance. This paper presents the first mathematic model for finding the last spawning date.
