Survial rate, growth, molt increment and intermolt duration of the larvae Orithyia sinica(Linnaeus) was measured on the larvae reared under the two different tempera ture conditions. Survival rate of each zaeal stage was 91-95% in 20℃ and 83.3-86.6% in room temperature. Mean carapace length of zoea-1, zoea-2 and zoea-3 was 1.17, 1.59 and 2.27 respectively. Intermolt duration of each zoeal stage increased steadly with increase of number of instars. Intermolt increment was positively propotional to the age and size of the larvae. Mean increment was 36-39% in 20℃ and 35-41% in room temperature 21-24℃
