| 摘 要： | 本试验测定了不同发育阶段柑桔白轮蚧的发育起点温度（Ｃ）和有效积温（Ｋ）。结果表明：在１８─３０℃范围内，该蚧的发育历期随温度的升高而缩短，发育速率与温度呈直线关系。得到了柑桔白轮蚧各虫态及雌虫全世代的发育起点温度和有效积温。结合雅安地区气象资料推算出该蚧年发生代数为４－５代。

| Abstract: | Aulacaspis citri Chen is one of important pest of citrus. The experiment Contains: estimating developmental threshold (C), effective thermal constant (K) and generation numbers of one year. The results showed that under18-30℃ the duration decreased and the development rate increased rectilinearlywith temperature. The developmental threshold and thermal constant of each development stage were obtained. Generation numbers are 4-5 in Yaan. |
