| 摘 要： | 在恒温20,23,25,27,30℃下,对沈阳市国槐尺蠖Semiothisa cinerearia Bremeret Grey各虫态的发育历期,发育起点温度和有效积温进行了研究。结果表明,随着温度的升高,发育历期逐渐缩短;国槐尺蠖卵,幼虫,蛹,成虫期和世代发育起点温度C分别为(4.20±0.95),(5.80±0.95),(8.28±0.30),(16.92±0.50)和(9.06±0.21)℃。相应的有效积温K分别为(71.3±2.3),(300.5±14.3),(354.2±8.3),(52.4±2.59)和(752.76±10.5)日.度。根据发育起点温度和有效积温,预测出国槐尺蠖在沈阳的年发生代数为3.4～3.6代,其结果符合实际发生情况。 |

| Abstract: | The developmental periods,the development threshold temperature （DTT） and effective accumulative temperature （EAT） of Semiothisa cinerearia Bremer et Grey were studied under five constant temperatures in the laboratory. The results showed that egg,larva,pupa and adult can normally develop from 20℃ to 30℃. The DTT of egg,larvae,pupa,adult and the yearly generation were （4.20±0.95）,（5.80±0.95）,（8.28±0.30）,（16.92±0.50） and （9.06±0.21）℃respectively,and their EAT were （71.27±2.29）,（300.529±14.31）,（354.20±8.28）,and （52.45±2.52） and （752.79±10.46） degree-day respectively. Based on the investigation of its annual life history,it is concluded that the occurrence of S. cinerearia was 3.4～3.6 generations annually in Shenyang.The results are according with practical situation. |
