Impact of Intercropping System on Soybean Pod Borer, Cydiaptychora (Meyrick)

Afield investigation was carried out at AICRP Soybean, UAS Dharwad, Karnataka, India. Soybean (JS 335) was intercropped with different crops viz., Onion, Foxtail millet, Cotton, Chilli, Green gram, Red gram, Maize, Ground nut and Castor. Among different intercropping system, Soybean + Red gram system recorded lowest per cent pod damage (12.67%). Whereas less per cent seed damage (41.00%) and larvae per pod (1.60) noticed in Soybean + Maize system. Correlation studies reveals there was significant and positive relationship between percent pod and seed damage (0.733*). While per cent pod damage and larvae per pod (0.853**) and per cent seed damage and larvae per pod (0.901**) showed highly significant and positive correlation.
