| 摘 要： | 在恒温条件下,观察了21～33℃范围内甘蔗红尾白螟蛹的发育历期,并测定了其发育起点温度和有效积温。结果表明,红尾白螟蛹发育历期与温度呈负相关,蛹的发育起点温度为(14.129±0.529)℃,有效积温为(191.003±7.461)℃,发育历期预测式为N=(191.003±7.461)/T-(14.129±0.529),可用于成虫发生期和防治适期的预测。

| Abstract: | Development periods of Tryporyza intacta pupa in sugarcane were observed at constant temperature ranged from 21 ℃ to 33 ℃,and the developmental threshold temperature and effective accumulative temperature were tested.The results showed that T.intacta pupa development periods were negatively correlated with temperature,and developmental threshold temperature and effective accumulative temperature were 14.129±0.529 ℃ and 191.003±7.461 degree-day respectively.The predictive development periods equation was established as N=(191.003±7.461)/T-(14.129±0.529),which could be applied for its adults occurrence and control period forecast. |
