在自动控制温度和光照长度的小实验室内，采用二次回归通用设计，对截形叶螨的繁殖方面进行了研究，其结果表明：产卵高峰期和子代性比与温度和光照长度无关；产卵期随着温度的升高呈直线缩短的函数关系；日均产卵量随着温度的升高呈直线增加的函数关系，光照长度对日均产卵量呈开口朝下的抛物线函数关系；雌螨寿命在本试验范围内最短寿命为17天左右，最长寿命为69天左右.
In a small laboratory with automatic control of temperature and light length, a quadratic regression general design was used to study the reproduction of Tetranychus urticae. The results showed that the spawning peak and progeny were independent of temperature and light length ; The spawning period showed a linearly shortened function as the temperature increased; the average daily fecundity increased linearly with increasing temperature, and the parabola function of light length on average daily fecundity Relationship; Female mites longevity within the scope of this test the shortest life expectancy of about 17 days, the longest life expectancy of about 69 days.
