研究了温度(17、21、25、30和35℃)对Q型烟粉虱种群生活史特征的影响。温度依赖关系的特征是未成熟发育率、未成熟存活率、繁殖力、寿命和内在增长率。发育时间从30摄氏度的20天到17摄氏度的56天不等，最低温度阈值估计为10.2摄氏度。未成熟发育的最适温度为32.5摄氏度。总繁殖力(每雌鱼产卵量)从105.3(21摄氏度)到41(35摄氏度)不等。寿命随温度升高而降低。固有增长率从0.0450(17摄氏度)到0.123(30摄氏度)不等。利用温度与生活史参数之间的函数关系来评价温度对种群动态的影响。这样的数学关系可以为未来人口模型的发展提供基础。
The influence of temperature (17, 21, 25, 30 and 35 degrees C) on life-history traits of a Q-biotype Bemisia tabaci population on tomato is studied. Temperature-dependent relationships are characterized for immature developmental rate, immature survival, fecundity, longevity and intrinsic rate of increase. Development time vary from 20 days at 30 degrees C to 56 days at 17 degrees C and the lowest thermal threshold is estimated at 10.2 degrees C. The optimal temperature for immature development is 32.5 degrees C. Total fecundity (eggs per female) ranges from 105.3 (at 21 degrees C) to 41 (at 35 degrees C). The longevity decreases with temperature increase. The intrinsic rate of increase ranges from 0.0450 (at 17 degrees C) to 0.123 (at 30 degrees C). The functional relationships between temperature and life-history parameters are used to evaluate the effect of temperature on the population dynamics. Such mathematical relationships could provide a basis for future development of population models.
