| 摘 要： | 研究了温度和光照对棉铃虫(Helicoverpa armigera)种群滞育形成的作用。结果表明,温度低于24℃、光照短于12h为诱导滞育的适宜条件。20℃、22℃、24℃和26℃下滞育的临界光周期分别为13h43min、13h8min、12h41min和12h7min.5～6龄为主要滞育敏感虫期。在南京地区,该虫滞育临界光周期为13h左右,出现于9月20日前后;9月上旬温度状况与滞育比例关系密切。

| Abstract: | Studies on the effect of temperature and illumination on the diapause induction of cotton bollworm (Helicoverpa armigera) population in Jiangsu show that temperature below 24℃ and illumination of < 12h were optimal for diapause induction. The critical length of illumination at 20,22,24 and 26℃ were 13h and 43min, 13h and 8min, 12h and 4min, and 12h and 7min, respectively. The fifth and sixth instar larvae were the sensitive stages of diapause indution. Their critical length of illumination was about 13h, which occurs in mid-September in Nanjing region, and the temperature in early September was found to be greatly related with the diapause rate. |
