Abstract The rice mite, Steneotarsonemus spinki Smiley (Acari: Tarsonemidae), was observed for the first time as a serious pest of crops in West Bengal. Susceptibility and tolerance level twelve most commonly grown cultivars were evaluated against mite during wet season 2002–2003. Damage, visible on leaf sheaths grain brownish patches, led to an increase chaffy loss yield. None found be resistant, however, MTU-7029 (83.33 mites/sheath) IR-64 (160.00 recorded 'tolerant' IR-36(570.00 IET-4094...
