摘 要 ：采用生命表分析、生存分析、“王-兰-丁”模型及线性模型等分析方法，对15~28℃温区的5个恒温处理朱砂叶螨（Tetranychus cinnabarinus）实验种群进行了系统研究。结果表明，此温区内，种群在生殖、发育和生存3方面，有明显的温度效应：内禀增长力、周限增长力、净增殖力和平均日产卵量、世代平均周期、及种群倍增时间的倒数呈线性增长；而平均寿命、最大死亡年龄，随温度升高而递减；性比和实际产卵天数对温度不敏感。种群在生殖、发育和生存三者之间，采取了较为“折衷”的策略：8℃为发育临界点；13℃左右为生殖和种群增长临界温度；22℃左右为生殖和种群增长最适温度；30℃左右为发育最适温度。

Abstract:The effect of temperature increase from 15℃ to 28℃ on population dynamics pertaining to analysis on life table and survival analysis of Carmine spider mite (Tetranychus cinnabarinus) fed with White mulberry (Morus alba) was investigated under laboratory condition. Analysis using both linear and ‘Wang-Lan-Ding’ models based on population parameters was performed. Results revealed the increment of net reproductive rate（R0）, finite rate of increase（λ），intrinsic rate of natural increase（rm）, eggs laid per female per day, the reciprocal of doubling time for population（Dt）and mean generation time（T）were all represented linear relation with temperature increasing, whereas the average life and the maximum mortality age were both decreased with temperature increasing. Ratio of male/female and practical oviposition duration were basically unchanged within the temperature range. The population selected ‘trade-off’ strategy among reproduction, development and survival. Threshold temperature of development (female), threshold temperature of reproduction and population growth, optimal temperature of reproduction and population growth, optimal temperature of development were approximately 8, 13, 22℃ and 30℃, respectively.
