摘要
在20℃,22℃,25℃,28℃和30℃,LD14:10下观察卵孵化的时辰节律。结果表明,在这五种温度下,卵孵化呈现两个孵化高峰:第一个高峰出现在6:00-6:59,也就是黎明这段时间;第二个高峰出现在19:00-19:59,也就是黄昏这段时间,但此时的孵化率明显低于前者。
At 20, 22, 25, 28 and 30℃ under LD14：10, hatching rhythm of eggs in Colaphellus bowringi was systematically investigated. The results show that there were two distinct hatching peaks under 24-h light-dark cycle, one occurred at 6：00-6：59; another at 19：00-19： 59. However the fust peak was much higher than the second peak.
