| 摘 要： | 研究了大猿叶虫成虫的过冷却点、低温生存能力和越冬情况。结果表明:大猿叶虫成虫的过冷却点在越冬前期降低,后期升高,1月份降至最低值-22.3℃。Lt50和Lt95均随温度的降低而缩短。越冬后期,成虫的死亡率达24.6%。

| Abstract: | The supercooling point(SCP),the ability for survival under low temperature and overwintering of Colaphellus bowringi Baly were studied.The results showed that the SCP of adult reduced firstly and then ascended.The lowest SCP,-22.3℃,appeared in January.Lt_(50) and Lt_(95) were both shorten with decline of temperature.In the late period of overwintering,the mortality rate of adult reached 24.6%. |
