摘要
采用20、22、25、27和30℃5个恒定温度对红脉穗螟Tirathaba rufivena Walker各虫态的发育起点温度和有效积温龟行了测定。结果表明，发育历期随温度的升高而缩短；卵、幼虫、蛹、产卵前期和全世代的发育起点温度分别为11．22、12．77、11．63、11．43和12．17℃；有效积温分别为59．64、265．93、136．20、26．71和487．39d·℃。该虫在海南年发生8～10代。
The developmental threshold temperature and effective accumulative temperature of Tirathaba rufivena Walker were tested at five constant temperatures （ 20, 22, 25, 27, 30 ℃ ）. The results showed that its developmental duration became shorter along with the increase of temperature. The developmental threshold temperatures of egg, larva, pupa, pre - oviposition and whole generation were 11.22, 12.77, 11.63, 11.43 and 12.17℃ respectively, and their effective accumulative temperatures were 59. 64,265.93,136.20, 26.71 and 487.39 d ·℃respectively. This insect pest occurred annually 8 -10 generations in nainan.
