蚊种群的数学模型是研究种群动态机制和制订防治方案的有效工具。以往的模型研究多偏重不同阶段死亡率对成蚊密度的影响,模型的评价则根据观察值与模型值作对应比较。因成蚊密度观察值的误差很大,所以对应比较往往不可靠。本模型则以季节消长模式作为评价标准,将全年的成蚊密度变化与模拟值进行比较。 本模型将蚊生活史分为几个阶段:虫卵
The mathematical model of mosquito populations is an effective tool for studying population dynamics and developing control programs. Previous model studies mostly focused on the effects of mortality at different stages on the density of adult mosquitoes. The evaluation of the model was based on the observed values compared with the model values. Due to large errors in the observed values of adult mosquitoes, the correspondence is often not reliable. The model uses the seasonal pattern of growth and decline as the evaluation criteria to compare the annual adult mosquito density changes with the simulated values. The model divides the mosquito’s life history into several stages: the egg
