| 摘 要： | 在自然变温条件下,研究金纹细蛾LithocolletisringoniellaMatsumura各虫态发育历期。结果表明,成虫产卵前期、卵、幼虫、蛹及全世代的发育起点温度分别为7.5,5.2,10.4,11.3和7.1℃,有效积温分别为40.6,59.7,102.2,15.4和203.1日.度。根据有效积温法则,预测该虫在山东省1年发生4~6代,第1、2代成虫发生期分别为5月下旬和6月下旬。

| Abstract: | The developmental durations of different stages of Lithocolletis ringoniella Matsumura were investigated at room temperatures.The results showed that the threshold temperatures of adult pre-oviposition,egg,larval,pupal stages and whole generation were 7.5,5.2,10.4,11.3 and 7.1℃ with effective accumulated temperature of 40.6,59.7,102.2,15.4 and 203.1 degree-day respectively. It is predicated that there were 4～6 generations per year occurred in Shandong Province.The adults of 1st and 2nd generations emerged in late May and late June in Taian, Shandong Province. |
