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 ;线性模型的相关系数均达到显著水平或极显著水平 Based on the experimental data of the developmental rate of whitefly at 5 constant temperatures, the effects of insect development rates on the developmental stages of the whitefly were examined using three models (linear daily model, L ogistic model and Wang model) The results show that the two nonlinear models have a high fitting effect, χ2 reaches a significant level, the fitting effect of Wang model is better than that of Logistic model, the correlation coefficient of linear model reaches a significant level or Very significant level
