[Estimation of the migration source for the white-backed planthopper Sogatella furcifera (Horváth) (Homoptera: Delphacidae) immigrating into Kyushu in June]
Japanese Journal of Applied Entomology and Zoology 49 (4), 187-194
Abstract: A 3-dimensional backward trajectory analysis was applied for estimating the migration source of the white-backed planthopper that immigrated into Kyushu, western Japan in June from 1987 to 2001. The results showed that the coastal regions of Fujian province in China and Taiwan were found to be possible sources. The migration duration taken to travel between the sources and Kyushu was estimated to be about 36 or 48 h. The comparison between 2-dimensional and 3-dimensional analyses indicated that the former method had a bias toward the southwest in estimating the source.
