Effect of Photoperiod on the Development of Spermophora senoculata (DUGÈS) (Araneae: Pholcidae)

[摘要] References(4)The nymphs of Spermophora senoculata (DUGÈS) were reared under 3 different photoperiods; natural, long (LD-16:8) and short (LD-10:14). Upon rearing under natural and long photoperiods, there was no difference in the developmental process. Upon rearing under a short photoperiod, however, development showed a retardation of 50-70 days due to prolongation of all instars other than the last one as compared with that under the other conditions.
