MELOIDOGYNE ORYZAE N. SP. (NEMATODA, MELOIDOGYNIDAE) INFESTING IRRIGATED RICE IN SURINAM (SOUTH AMERICA) BY P. W. TH. MAAS 1, HETTY SANDERS 2 and JANNIE DEDE 1 1 Plantenziektenkundige Dienst, Wageningen, the Netherlands, and 2 Landbouwhogeschool, Wa- geningen, the Netherlands Meloidogyne oryzae n. sp. is described from rice. It is distinguished by the second-stage larvae 500-615 µm long. It differs from its closest relative M. graminicola by longer second-stage larvae and males with longer stylets, by the dilated rectum in second-stage larvae, and by the more clearly offset lip region in females. It reproduces on rice, Fimbristylis-grass, wheat, tomato and potato, but not on maize, cotton, peanut, sweet pepper, sweet potato, and water melon. Root-knot nematode infestation in irrigated rice was observed at the Wage- ningen rice scheme in Surinam in 1971. Infested plants were stunted and showed root-knots of 2 to 3 mm. Tillering was reduced and the leaves were attacked by Helmintho.rporium oryzae, a weakly parasitic fungus. Though infestation always occurred at the higher spots within a field, the nematode appeared to be very well adapted to irrigated rice (Van Halteren, 1972). Morphological and hostplant studies were carried out with two living popula- tions of this rice
