甘薯粉虱、烟粉虱的能力。在实验室中研究了在一系列环境条件下的生存能力。所调查的温度和湿度范围与以色列烟粉虱夏季迁徙期间的正常气候范围相一致。将成年白蝇关在小型试验笼中，暴露在温度（25、30、35和41摄氏度）和相对湿度（20、50、80和100%）的组合环境中，时间分别为2、4或6小时。建立了描述四维表面的逻辑回归模型，该模型将存活率定义为时间、温度和湿度的函数。使用逐步回归排除非显著项，线性预测包括温度，温度和时间的乘积，湿度和时间。该模型解释了75%的方差。拟合回归模型的重新参数化表明，生存潜力受前10小时内普遍存在的温度条件的制约。白蛉在暴露2小时后的存活率范围从25℃和100% RH下的约90%存活率到
The ability of the sweet potato whitefly, Bemisia tabaci Gennad., to survive a range of environmental conditions was investigated in the laboratory. The range of temperature and humidity investigated corresponds to the normal climatic range during B. tabaci's summer migration in Israel. Adult whiteflies confined to small test cages were exposed to combinations of temperature (25, 30, 35, and 41 degrees C) and relative humidity (20, 50, 80, and 100%) for periods of 2, 4, or 6 h.A logistic regression model describing the four-dimensional surface defining percent survival as a function of time, temperature, and humidity was developed. Using stepwise regression to exclude non-significant terms, the linear predictor included temperature, and the products of temperature and time, and humidity and time. The model accounted for 75% of the variance. A reparameterization of the fitted regression model suggests that survival potential is conditioned by temperature conditions prevailing during the previous 10 h.Whitefly survival after 2 h exposure ranged from approximate to 90% survival at 25 degrees C and 100% RH, to
