To establish the indoor-rearing system of the emma field cricket, Teleogryllus emma, the effects of temperature on development and reproduction of the emma cricket have been studied. The influence of temperature on developmental periods of emma field cricket was investigated under the eight temperatures of 15, 18, 21, 25, 27, 29, 31 and $35^{circ}C$, under $60{pm}5%$ R.H. and 16L:8D photoperiod. The developmental periods of T. emma nymphs had a range of 124.8 days to 44.4 days at the temperature of $21^{circ}C$ and $35^{circ}C$, respectively. At $15^{circ}C$ and $18^{circ}C$, however, all tested individuals died before emergence. The highest survival rate was 90% at $25^{circ}C$, but there were no statistically significant differences among the temperatures. The adult weight increased with increasing temperatures although the weight at $35^{circ}C$ was decreased. In addition, the influence of temperature on reproduction of emma field cricket was investigated under three temperatures $22^{circ}C,;25^{circ}C;and;28^{circ}C$, under $60{pm}5%$ R.H. and 16L:8D photoperiod. The longevity of female/male adults were 65.8/79.2 days, 68.5/67.8 days, 46.8/57.4 days at the temperature $22^{circ}C,;25^{circ}C;and;28^{circ}C$, respectively. The preoviposition periods were 32.5 days at $22^{circ}C,;22.9^{circ}C$ days at $25^{circ}C$ and 22.1 days at $28^{circ}C$. The highest average fecundity per female was 737.3 at $25^{circ}C$.
