摘要
通过实验种群资料 ,用悬链线方程拟合了褐飞虱若虫期的发育速率与温度的关系 ;用抛物线方程拟合了若虫不同龄期的死亡率与年龄的关系。结果表明 ,模拟效果良好 。
Based on the data from the experimental population researches, the models of developmental and survival rate of Nilaparvata lugens (BPH) nymphs were constructed in different growth stages of rice. The results indicated that the models, which were presented as v(t)=K·A·B/[1+e -r(T-T 0) ], A=1-e -(T-T L)/δ L , B=1 e -(T H-T)/δ H for developmental rate and S(T)=α+βT+γT 2 for survival rate, were suitable for simulating nymph′s developmental and survival rate of BPH nymphs.
