Short daylengths accelerate nymphal development of the emma field cricket, Teleogryllus emma (Orthoptera: Gryllidae)

In order to establish an indoor-rearing system for the emma field cricket, Teleogryllus emma, the effects of seven photoperiod regimes (0L:24D, 8L:16D, 10L:14D, 12L:12D, 13L:11D, 14L:10D and 16L:8D) on development and reproduction of T. emma have been analyzed. The nymphs developed faster in the short than in the long photoperiods. Adult body weight was dependent on the nymphal period. The preoviposition period, oviposition period and the number of eggs laid in different photoperiods were not significantly affected by photoperiod.
