Abstract: Through the breeding and observation at constant temperature (26±1) ℃, the life table of laboratory population of Ophraella communa was constructed. The development duration of egg, larva, pupa, and preoviposition of O. communa was 7.51, 12.14, 7.67, and 4.75 days, respectively. The survival rate in each developmental period was from 77% to 94%, being the highest for egg, and the lowest for the 3rd instar larva. The population survivorship curve fitted Deevey’s type Ⅱ, the number of eggs laid per female was 193.8, the population trend index (I value) was 36.95, the average generation period (T) was 31.37 days, and the innate capacity (γm) and finite rate (λ) of population increase were 0.095 and 1.10, respectively.
