摘要
本研究利用人工气候模拟设备,在室内条件下研究烟蚜Moyzus perMcae(Sulzer)成蚜的寿命、生殖能力与温度变化的函数关系,研究的重点是高温或极端高温以及高温的持续时间对蚜虫生物学特性的影响。研究结果表明,在人工模拟的夏季平均气温温度段20-30℃内,蚜虫的发育速率以27.5℃为拐点,在20-27.5℃范围内发育速率随温度的升高而升高;当温度超过27.5℃,蚜虫发育速率反而降低。研究结果还揭示温度(尤其是高温)的持续时间是降低蚜虫的存活时间及其生殖能力的重要因素。
The growth rate of Myzus persicae (Sulzer) was studied under laboratory condi-tions. Results indicate that the growth rate is the function of temperatures between 20 and 27.5℃ . High temperatures, above 27.5℃, may slacken the growth rate of M. persicae.In this study, the influence of extremely high constant temperatures (28-35℃) and the durations (in hours within one day) of these temperatures on the survival duration and repro-duction of female adult M. persicae was also measured. Results indicate that the duration of extremely high temperatures is one of the key factors severely reducing the reproduction and shortening the survival time of female adults of M. persicae.
