Larval populations of Meloidogyne graminicola in soil at Cuttack, India, were large during December to February when soil temperatures were 20.9 deg C and below. Populations were small in March, July and August and very small in April, May and June when the soil temperature was 31 deg C. Greatest numbers of galls on rice roots were found from January to March and of egg masses from February to March.
