The box tree pyralid, Glyphodes perspectalis, was reared on an artificial diet based on dried powder of box tree leaves, Buxus microphylla var. koreana, and INSECTA F-II (Nihon Nosan Co., Ltd) at a ratio of 3:7 (w:w) and analyzed in their developmental characteristics from $1^{st}$ to $4^{th}$ generation. The developmental period of larva reared on artificial diet was longer than that of larva reared on host plant. Significant difference in larval period was also observed between $1^{st}$ and other generation groups. Pupation rate was the highest in $4^{th}$ generation followed by $3^{rd}$, $2^{nd}$, $1^{st}$ and host plant group. Significant difference in pupal period was noted between $1^{st}$ and 3rd generation group. Emergence rate was the highest in $4^{th}$ generation group followed by $3^{rd}$, host plant, $1^{st}$ and $2^{nd}$ generation group. There is a significant difference in male and female size between $1^{st}$ and $4^{th}$ generation group. Our result indicated that stable rearing of box tree pyralid through the year is possible by artificial diet, and the best adaptation to artificial diet was achieved at $4^{th}$ generation.
