Abstract
The rice water weevil, Lissorhoptrus oryzophilus, was first detected in Japan in 1976 in a paddy field, in Tokoname, near Nagoya. This weevil is a recent invader and is assumed to have entered with hay from California. Ten years later, the weevil succeeded in spreading throughout all Japanese paddy fields and also expanded to Korean, Taiwan and east China. The rice water weevil now is regarded as one of the common insect pests of rice in these areas. Investigations on taxonomy, biology, population dynamics, damage and economic importance, estimation of population density and forecasting, and control are reviewed.
