Simultaneous catches of migrating planthoppers by tow-net 1m in diameter and 1.7m depth were obtained at Chikugo (33°12'N, 130°30'E), Naze(28°23'N, 129°30'E)(only in 1978), and Naha(26°14'N, 127°41'E) in 1977 and 1978,in addition to the catches at the Weather Station on the East China Sea(31°N, 126°E). Five and 6 peaks were recognized in 1977 and 1978,respectiviely. The first 4 peaks in 1977 and the 3 ones in 1978 were apparently related to the frontal system and no synchronous catches were obtained between Chikugo and Naha. Three peaks in Naze in 1978 showed synchronization with those in Naha and 3 with those in Chikugo. Eastward movement of air-mass from the Chinese continent without relation to the frontal system which occurred at the final stage of the rainy season induced synchronous catches in the three locations. On the Sea, 3 and 4 peaks were recognized in 1977 and 1978 respectively, all corresponding to the last peaks on the land. Most peaks showed a clear synchronization with those in Chikugo and Naze. It was strongly suggested that the source of the migrating planthoppers in this season might be located in the Chinese continent.
