Abstract
As increasing utilization of Tenebrio molitor for industry, establishing effective conditions of indoor mass-rearing system become more important. For this reason, the aim of this study was to identify the physiological characteristics of Tenebrio molitor in different range of temperatures, photoperiods and rearing densities for mass breeding. As a result, their egg had above 70% hatching rate at $17.5{\sim}27.5^{\circ}C$ and the egg period was shown 5~7 days in $25{\sim}35^{\circ}C$. Consequently, in the consideration of the hatching rates and egg periods, the optimal indoor temperature for rearing was $25{\sim}27.5^{\circ}C$. Furthermore, development period of larvae in mass breeding system was shorter than individual breeding system under all the conditions of temperature. Also, the pupal weight was higher in mass breeding system except for $20^{\circ}C$ and $25^{\circ}C$. Considering elasticity of demand and weight of production, the effective condition was mass-breeding system at $25^{\circ}C$. In photoperiodic condition, the shortest of larval period was 157.35 day in 14L : 10D.
