Abstract : This study investigated the seasonal fluctuation of plant parasitic nematodes, i.e. Hoplolaimus indicus [Basirolaimus indicus], Helicotylenchus indicus, Rotylenchulus reniformis, Tylenchorhynchus mashhoodi, Tylenchus filiformis and Hemicriconemoides mangiferae, around the roots of mango, Mangifera indica. The population was investigated at 10, 20 and 40 cm depths. Seasonal fluctuations have a direct effect on the nematode population. The population was larger at 10 cm depth, followed by 20 and 40 cm depths. The largest nematode population was observed when the percentage of soil moisture was high. Both soil temperature and soil moisture were equally important. The soil pH also affected indirectly the nematode population densities.
