| 摘 要： | 试验测定了不同发育阶段十一星瓢虫(Coccinella undecimpunctata L.)的发育起点温度(C)和有效积温(K).结果表明:在16～32℃时,该虫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.得到了十一星瓢虫各虫态及全世代的发育起点温度和有效积温.并得出各虫态(龄)的发育速度与温度的10个关系式.

| Abstract: | The developmental threshold(temperature) and effective accumulated temperature of Coccinella undecimpanctata in different development stages were determined by the experiment.The results showed that the development period decreased as the increase of temperature within the 16～32℃ range and a linear relationship was found between the developmental velocity and the temperature.The threshold temperature and effective accumulated temperature of it were obtained.The relationship between the developmental velocity and temperatures was described by ten mathematical equations. |

| Keywords: | Coccinella undecimpanctata developmental period threshold temperature effective accumulated temperature |
