Abstract
Cotton is damaged by over 200 species of insect pests from sowing to harvest. Among them, stem weevil has been reported as an important pest. Earlier, it is not a serious menace in regular season crop and only less than 10% mortality of plants is encountered. In the recent years, farmers tend to raise cotton during the off-season. Under such conditions, more than 60% mortality of cotton plants is observed and is becoming a serious botheration to cotton growers. Recently its outbreak has been reported from Bhadradri Kothagudem district of Telangana. The information about the pest is very scanty. In this connection, this paper was written describing about the pest origin, systematic position, bionomics, life history, nature and symptoms of damage, ecology and seasonal occurrence and integrated pest management practices.
