The necessity for low temperature treatment of Emma Cricket Eggs, Teleogryllus emma, to dormancy breaking and the method of increasing hatching rate after low temperature treatment were investigated. Emma Cricket Eggs were treated by constant temperature, room temperature, low temperature, step‐down low temperature. As a result, constant temperature treatment was the lowest on hatching rate. The hatching rates of the rest of other temperature treatments were not different statistically (one‐way ANOVA). In other word, low temperature treatment was not necessary to dormancy breaking. But low temperature treatment was necessary to control individual number of Emma Cricket, Teleogryllus emma, on the mass indoor‐rearing system. And the step‐up temperature treatment was necessary to increase hatching rate after low temperature treatment.
