Photoperiodic sensitivity in adults of Aelia fieberi (Heteroptera: Pentatomidae)
- N/A
Photoperiodic sensitivity was examined in adults of a bivoltine bug, Aelia fieberi Scott, by exposing insects to long-day or short-day conditions al 25°C. The adult diapause of A. fieberi is facultative, induced by short-day photoperiod. Adults reared from eggs under long-day conditions began to lay eggs, whereas those reared under short-day conditions entered diapause. Both nondiapause and diapause adults were sensitive to photoperiod. The adults of the first and the second generation collected from the field were also sensitive to photoperiod. However, after overwintering, adults did not show photoperiodic sensitivity.
