For poikilotherm animals such as insects, extreme temperatures can be a severe issue in continental regions. Aphids, which reproduce in spring and summer by viviparity, are prone to death in hard winter conditions. These species exhibit reproductive plasticity adapted to winter by producing oviparous females in autumn, which lay overwintering eggs. This switch is driven by photoperiodism, and long nights are sufficient to trigger the change in reproductive mode. Global transcriptomic analyses… CONTINUE READING
