| Research Abstract |
In the present study, we clarify that both diapausing pupae induced by a short photoperiod at 20℃ (SD), and by a long photoperiod (LD 16:8h) at 15 °C (LT)of the cotton bollworm Helicoverpa armigera (Hubner) changed composition of phospholipid and that ratio of unsaturated fatty acid by cold acclimation. These results suggested that diapausing pupae of H. armigera maintained membrane fluidity under low temperature. However, after terminated diapause, composition of phospholipids was returned to the initial level.
