高氏瘤粉虱重要天敌——桨角蚜小蜂的发育速率模型

The developmental rate model of Eretmocerus sp.-an important natural enemy of Aleurotuberculatus takahashi

利用桨角蚜小蜂在 5个不同恒温下的发育速率试验数据 ,分析比较了 3种模型 (线性日度模型、L ogis-tic模型、王氏模型 )的有效性和实用性 .在整个温区内 ,Logistic模型和王氏模型的拟合效果较好 ,且王氏模型的拟合度高于 L ogistic模型 ,具有较好的实用性 .

By measuring the developmental rates of Eretmocerus sp. at 5 different constant temperatures, Linear Model, Logistic Model and Wang's Model were employed to describe the validity and practicability of relationship between the developmental rates of Eretmocerus sp. and temperatures. It was found that the simulation effects of Logistic Model and Wang's Model were excellent in the whole range of temperature and Wang's Model had higher simulation effect and better practicability than Logistic Model. In the optimal range of temperature, correlation coefficient of Linear Model reached the level of extreme significance.
