摘要 利用稻粉虱在 5个恒温下发育速率的试验数据 ,分析比较了昆虫发育速率 3种模型 (线性日度模型、L ogistic模型、王氏模型 )对稻粉虱各虫态及全世代发育速率的拟合效果 .结果表明 ,两种非线性模型均具有较高的拟合效果 ,χ2 达到极显著水平 ,王氏模型的拟合效果比 Logistic模型好 ; The experimental data of developmental rates of rice whitefly ( Aleurocybotus indicus David et Subramaniam) at five constant temperatures were used to analyse and compare the fitting effects of three entomological developmental rate models (Linear Model, Logistic Model and Wang's Model) on the developmental rates at various stages and in the whole generation of rice whitefly. Both of the nonlinear models had high fitting effects and χ 2 value reached the level of extreme significance. Meanwhile, the fitting effect of Wang's Model was higher than that of Logistic Model and the correlation coefficient of Linear Model reached the level of extreme significance or significance.
