Fauna of plant parasitic nematodes in the temperate region of Japan: 1. Surveys in Shizuoka and Kagawa Prefectures.

 

Aphelenchoides, Criconemella, Helicotylenchus, Meloidogyne, Paratrichodorus, Paratylenchus and Rotylenchulus were detected in vegetable and ornamental plant fields of Shizuoka Prefecture. Of these, M. hapla and M. incognita, the most harmful nematodes, were detected in rose gardens at a high density. R. reniformis and Pratylenchus spp. were detected in vegetable and rose fields. H. dihystera and Paratrichodorus porosus were found infrequently. In Kagawa Prefecture, Shikoku district, 6 genera of nematodes including the same genera or species as those in Shizuoka except for Tylenchorhynchus were detected. Among these M. incognita was detected mostly in carrot samples at a very high density, causing damage to the crop. Tylenchorhynchus spp.and H. dihystera were detected on bonsai pine trees, showing yellowish leaves and decayed rootlets.
