Eradication of Radopholus similis in Japan (details)

The major exotic pests which have recently invaded Japan are the following: Globodera pallida (in 1972), Trialeurodes vaporariorum (1974), Lissorhoptrus oryzophilus (rice water weevil in 1976), Thrips palmi (1978), Liriomyza trifolii (1990) and Frankliniella occidentalis (1990). The example of introduction into Japan and eradication of the burrowing nematode, Radopholus similis (EPPO A2 quarantine pest) is described. The occurrence of R. similis in Japan was first confirmed on ornamental plants growing in Hachijo-jima Island, in October 1966. It was suspected that the source of introduction was Anthurium seedlings which were imported in large quantities from Hawaii (US). Detection surveys were carried out on approximately 10,000 plants (ornamentals, fruit trees and vegetables) cultivated on Hachijo-jima Island, and infestations were found in 47 plants. Eradication measures were applied: prohibition of movement of plants from the quarantined area, destruction of host plants and disinfestation of the facilities where infestation was found. During the following years, the nematode could no longer be found, and the eradication was considered successful by December 1969.
