摘要
在16-32℃范围内的7个温度下测定了温度对北京油葫芦生长发育的影响。温度与北京油葫芦各发育阶段均成直线相关。卵和若虫发育起点温度分别13．86℃、12．96℃，有效积温常数分别为199．9d·℃、789．9 d·℃。成虫的寿命随温度的升高而缩短，产卵量在24-28℃条件下最高，平均可达1400粒／雌。同时在卵孵化过程中，低温能帮助解除滞育作用。
The effect of temperature on the development of Teleogryllus emrnaOhmachi ＆ Matsuura was studied. The results showed that is line relation between temperature and development of Teleogryllus emrnain different stages. The threshold temperature of development for eggs and larvae was 13.86℃ and 12.96℃, and the thermal constant for these stages was 199.9 and 789.9day - degree.The life of adult decreased for temperature and the reproduction of adult was tiptop at 28℃. At the same time the low temperature played an important role at the hatch process of eggs of Teleogryllus emma.
