Abstract: This paper analyzed the relationships between occurrence area attacked by soybean pod borers in China during 1952-2001 and 74 atmospheric circulation parameters from previous January to current April, and monthly and average different period combination of ocean temperature from 286 gridding points. The atmospheric circulation and ocean temperature factors were screened out. Through step regression, the occurrence area forecast models concerning atmospheric circulation and ocean temperature were established and verified separately. The results showed that the occurrence area attacked by soybean pod borers could be preferably simulated and predicted by these models. The forecast accuracy reached 88% by the atmospheric circulation model and 86% by the ocean temperature model through extending prediction for2002-2004.
