摘要: A method has been developed for predicting the overseas migration of Laodelphax striatellus (Fall,n) from eastern China to Japan and Korea. The method consists of two techniques: estimation of the emigration period in the source region and simulation of migration. The emigration period was estimated by calculating the effective accumulated temperature for the insect by use of real-time daily surface temperatures at the source. During the emigration period, migration simulations were performed twice a day, at every dusk and dawn. The prediction method was evaluated, by cross-validation using migrations in the 4 years from 2008 to 2011. The results showed that the emigration periods included the mass migrations, and that the method successfully predicted those migrations.
