The blowfly, Calliphora vicina entered larval diapause after cessation of feeding in third instar under the influence of photoperiodic conditions and age of the maternal generation. Adults reared under short-day conditions (12L-12D) produced diapause-destined progeny, whereas those reared under long-day conditions (18L-6D) produced nondiapause-destined progeny at 20°C. After transfer from long-day to short-day conditions, the adults began to produce diapause-destined progeny. Even under constant long-day conditions, aged adults produced some diapause-destined progeny. Furthermore, the variation in the duration of larval development in diapause larvae was larger when the parents were old.
