Rice insects are the major constraint to rice production. More than 250 insect species have been found in rice field in China. The outbreak regularity, the epidemic forecast and the integrated management of major rice insect species were studied for different rice cultivated forms for the past decades.A good progress has been made in the studies and utilization of the variety resistant. Some of improved rice lines with genetic resistance have widely been grown. A network of screening pesticides was established in the 1980' s and hundreds of new insecticides were evaluated for different rice insects. A national IPM program was conducted in five rice growing regions in recent years. The IPM technical strategies have already been developed. Today , IPM technologies have been implemented at the farmer level in this country.
