Abstract
A computer simulation model was constructed to explore the phonology of the Striped Rice Borer, Chilo suppressalis (Walker), in Korea. The phenological system model based on the concept of distributed time delay was written in the computer program 'INSECT' and simulated with the estimated parameters of the effective day-degrees (DEL) and the order of time delay (K) for determining the validity of the system model. The accumulated emergence curves obtained from the phenological model were slightly different from the observed light trap data at the early and late stage of the moth emergence in 1978. The differences between observed and simulated
Distributed Time Delay의 개념을 응용하여 이화명나방의 발생시기를 예측할 수 있는 Phenological System Model을 구성하고 이의 타당성검정을 위해 기존 병해충발생예찰자료 및 일별 기상관측자료를 이용하여 본 해충의 1세대 경과에 소요되는 유효적산온도(DEL)와 Delay의 차수 K치를 산출한 후 이화명나방의 누적우화율곡선을 전자계산기로 Simulation 하였다. 그 결과 Model에 의해 추정된 1978년의 6개 선정지점의 누적우화율곡선은 실측 누적유살수비율곡선과 매우 유사하였으나 우화 초기 및 후기에 다소 편재하는 경향이 있었다. 한편 실측
