Why is the number of days required for induction of adult diapause in the linden bug Pyrrhocoris apterus fewer in the larval than in the adult stage?
Original language description
Females of Pyrrhocoris apterus programmed for diapause by short days (SD) and those programmed for reproduction by long days (LD) retain photoperiodic information in continuous darkness (DD). Diapause programming in the adult stage requires 9-10 SD before transfer to DD to induce diapause in 80% of individuals. However, if the diapause programming starts after ecdysis of LD-larvae to the last instar, only 3 short days before transfer to DD are required for diapause in 80% of individuals. Surprisingly, if the newly ecdysed last instar LD-larvae are transferred to DD (thus they did not experience any SD), diapause occurs in 40% of individuals. Thus, the diapause information? present in LD-larvae is responsible for a lower number of SD required for diapause induction.
