摘要
通过5种温度(19℃,22℃,25℃,28℃,31℃)处理观察稻纵卷叶螟(Cnaphalocrocismedinalis Guenee)各虫态的发育及卵的孵化时间分布:用SIGMOID函数模拟该虫在不同温度下的发育率;用发育频数累积曲线描述卵的孵化时间分布.这两个模型都能比较精确地描述卷叶螟以温度为基础的发育动态.
The development time and rate of rice leaf—roller and the time distribution of its egg hatching were estimated in five temprature conditions(19℃, 22℃, 25℃, 28℃, and 3l℃).The simulation of development was made by sigmoid function and the time distribution of hatching was described by a development accumulative freguency curve.It was reported that these two models are suitable to simulate the temperature —dependent developmental dynamic of rice leaf —roller.
