Comparisons of Photosensitivity of Diapause during Larval Development among Different Geographic Populations of Helicoverpa armigera
摘要
Abstract
In order to understand whether there is geographic variation of photosensitive larval instar for diapause induction in Helicoverpa armigera, the sensitive stage for photoperiodic induction of pupal diapause was investigated by transferring larvae between long photoperiod (L16-.D8) and short photoperiod (L12:D12) under the condition of 20 ℃ in 3 different geographic populations (Yongxiu, 29. 04 °N, 115. 82 °E; Taian, 36. 15 °N, 116.59 ° E; Kazuo, 41.34 °N, 120.27 °E). When the photoperiodic background of L12:D12 was interrupted by 5 × L16,D8 at different larval stages, the most photosensitive stage occurred in the L4/4 to the L5/3 stages for Yongxiu population, the L3/5 to the L5/1 stages for Taian population and the L6 stage for Kazuo population. When Taian population and Kazuo population were exposed to alternating short photoperiod and long photoperiod, respectively, Taian population showed the most photosensitive stage before the fifth in-star, Kazuo population showed the most photosensitive stage after the fourth instar. These results reveal that the most photosensitive stages are different in different geographic populations in H. armigera.关键词
