种群能量动态模型

    1)种群生产量P模型:


式中,PmPeP分别为种群的死亡损量、蜕损失量和生产量;k为各个不同的调查时期;i1~4龄若虫和成虫;Mk,iSk,i分别为特定时间(即调查间隔期)k内的各龄死亡数和若虫发育完成数;Eiei分别为虫体和蜕的能量。

2)种群呼吸耗能量R模型:

式中,αβ分别为氧卡系数和田间活动修正系数;WkWk+1分别为第k和第k+1次调查时的生物量;ab为常数;DDk为第k次调查期间的棉蚜生理时间值;fTk)为第k次调查时的温度校正值。

3)种群排泄量FU模型:

式中,FU1FU2分别为棉蚜若虫和成虫的排泄量;FUiFUk,5分别为1~4龄若虫和成虫在k调查期内的生理学时间;Nk,5Sk,5分别为成虫数和发育进入成虫的数量;e为蜜露的热量。
