In this study, we considered the effects of climate change on phenology and abundance of rice insect pest, Chilo suppressalis (Walker). Phenological changes of C. suppressalis and their host plant rice were simulated to examine their phenological synchrony. And long-term census data were used to estimate the climate effect on survival rate of C. suppressalis. The occurrence time of C. suppressalis might be advanced under global warming condition. On the contrary, rice cultivation time will be delayed under global warming condition. C. suppressalis might be hard to settle down in paddy field because of asynchrony between C. suppressalis and rice. And the temperature increasing might change survival rate of C. suppressalis.
