Abstract

The species composition of stem borers prevalent in Assam during wet season 2004 and 2005 was studied. The results revealed that all the species of stemborers are prevalent in this region. Amongst the species, yellow stem borer (34 - 40% in 2004 & 22.54–77.41% in 2005) and white stem borer (39 - 43% in 2004 and 18.27 - 67.64% in 2005) showed consistently higher population over the other species at all the three stages of the crop growth.
