Liriomyza huidobrensis found in Japan
In Japan, Liriomyza huidobrensis (Diptera: Agromyzidae – EPPO A2 list) was found for the first time in Aomori Prefecture (north of Honshu) in July 2004, on various glasshouse crops. Studies done on specimens collected from Hokkaido and Honshu (Aomori, Miyagi and Yamaguchi Prefectures) showed that the Japanese specimens (as those obtained from China, Korea and Taiwan) belonged to the South American clade. The EPPO Secretariat had previously no data on the occurrence of L. huidobrensis in Japan. L. huidobrensis had been intercepted on consignments imported into Japan but not reported on Japanese crops, so far.
The situation of Liriomyza huidobrensis in Japan can be described as follows: Present, first reported in 2004, found in protected crops in Honshu (north) and Hokkaido.
