在前人研究的基础上［１，２］，我们已经了解到光照和温度乃是影响和决定棉铃虫是否进入滞育状态的关键外界环境因子。但光照和温度，哪一个在决定棉铃虫的滞育中起着更关键的主导地位，则无文献述及，为此，我们设计了如下几个实验，试图来解答这个问题以及进一步了解温度对?
Based on previous studies [1, 2], we have learned that light and temperature are the key environmental factors that affect and determine whether a cotton bollworm enters the diapause state. But light and temperature, which play a more critical dominance in determining diapause of H. armigera, are not documented, and for that reason we have designed the following experiments in an attempt to answer this question and to learn more about temperature ?
