Stick insect has several peculiarities like parthenogenesis, unique external features and dropping oviposition, so it is very hopeful to use for industrial insect. The oviposition was established by only female without fertilization with sperm of male which was not discovered during this study. The oviposition period was 37.3±14.9 days and the number of eggs per female was 41.5±16.5 eggs. The hatchability was 73.3% at 25℃and 66.7% after low temperature treatment(8℃, 60 days). The developmental periods and the length of egg were 100.9±4.2 days and 0.33±0.0cm, respectively, and the adult's life span was 49.7±16.0days. Differently other research which reported five nymph stage, the developmental stages of nymph showed five(62.9%) or six(37.1%) stages. The duration and the length of nymph increased according to the increase of nymph stage. Stick insect preferred the leaf of American locust, White oak, Chestnut, Bush clover in order but could be reared with food of the leaf of all these trees. Stick insects are herbivorus but made an attack each other when encountered in the small space. For sustaining mass rearing of stick insect, it is needed that the development of artificial diet and high density rearing method.
