摘要
测定柑桔潜叶蛾在６个温度下的发育、存活、生殖情况，根据实验数据所呈现的规律，建立了温度对柑桔潜叶蛾存活、生殖的数学模型．模拟结果表明，生物物理模型不仅能很好地拟合柑桔潜叶蛾发育与温度的关系，也能很好地拟合世代存活率及内禀增长能力与温度的关系；抛物线模型能很好地拟合潜叶蛾卵的孵化率、幼虫的存活率、成虫的产卵量和种群增长指数与温度的关系．当环境瘟度为３０℃时，内禀增长能力最大（ｒｍ＝０．１６６９）．相应的周限增长速率λ＝１．１８１６ｄ－１．世代平均历期Ｔ＝１５．９１００ｄ．净增殖率Ｒ＝１４．２４００．
The development,survival and reproduction of citrus leaf miner,Phgllocnistis citrella Stainton were observed under 6 constant temperatures.Based on regularities drawn from experimental data, the mathematical models describing the effect of temperature on the survival and reproduction of citrus leaf miner were established,By digital simulation, the biophysical model not only fitted well the relation between temperature and the developmental rate,but also fitted well the relation of temperature to the survival rate and the innate capacity for increase(rm).The relations of temperature to the hatching rate of eggs,survival rates of larvae,reproduction of adults,and population index for increasse (I) can be fitted significantly with parabolic model.The highest innate capacity for increase(rm=0.1669)was obtained at the constant temperature of 30℃.The finite rate of increase (λ),the mean length of generation and net reproductive rate(R) of the experimental population were 1.1816 d-6,15.9100 d,and 14.2400,respectively.
