中文摘要:淡剑纹灰翅夜蛾Spodopteradepravata(Bulter)在 22 ,25 ,28,31 ,34,36,38℃恒温条件下卵孵化率分别为 96. 00,91.00 ,83.90 ,84.81 ,83.60 ,80%和 0。高龄幼虫在低温环境下 ,一般随温度的降低、时间的延长死亡率增加。过冷却点为 (-6.81± 1.63 )℃ ,体液冰点为 (-3.5 1
英文摘要:The hatch-rate of Spodoptera depravata was 96.0,91.00,83.90,84.81,83.60,80.00% and 0 when the temperature was at 22,25,28,31,34,36 and 38℃ respectively. The mortalities of the larvae increased when the temperature dropped and the time delayed un
