A roving survey was undertaken in four districts of major soybean growing areas of northern Karnataka viz., Dharwad, Belgaum, Bagalkot and Bidar during Kharif 2006 and 2007. The average higher per cent stem fly incidence of 63.48 and 61.80 was recorded in Belgaum and Bidar districts, respectively. The lower stem fly incidence (12.67%) was recorded in Dharwad district and moderate incidence (22.91%) was noticed in Bagalkot district. The average higher per cent stem tunnelling of 29.83 and 28.69 was recorded in Belgaum and Bidar district, receptively. The moderate (10.57%) stem tunnelling was in Bagalkot district, while it was lower (8.17%) stem tunnelling in Dharwad district.

Abstract


A roving survey was undertaken in four districts of major soybean growing areas of northern Karnataka viz., Dharwad, Belgaum, Bagalkot and Bidar during Kharif 2006 and 2007. The average higher per cent stem fly incidence of 63.48 and 61.80 was recorded in Belgaum and Bidar districts, respectively. The lower stem fly incidence (12.67%) was recorded in Dharwad district and moderate incidence (22.91%) was noticed in Bagalkot district. The average higher per cent stem tunnelling of 29.83 and 28.69 was recorded in Belgaum and Bidar district, receptively. The moderate (10.57%) stem tunnelling was in Bagalkot district, while it was lower (8.17%) stem tunnelling in Dharwad district.
