| 摘 要： | 采用20、22、25、27和3O℃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进行了测定。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487.39 d.℃。该虫在海南年发生8~10代。

| Abstract: | The developmental threshold temperature and effective accumulative temperature of Tirathaba rufivena Walker were tested at five constant temperatures(20,22,25,27,3O ℃).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 Hainan. |
