Assessment of crop loss and economic injury level of maize stem borer, Chilo partellus (Swinhoe)

Manjunath Chouraddi and CP Mallapur

Investigations on assessment of crop loss and economic injury level of maize stem borer, Chilo partellus (Swinhoe) was carried out at Main Agricultural Research Station, Dharwad during kharif and rabi-summer 2010-11 and 2011-12. The percent yield loss increased with increase in larval density. The maximum yield loss of 85.30 and 84.72 percent occurred when 9 larvae/pl were released compared to minimum of 3.47 and 1.27 percent in 1 larva/pl treatment during kharif and rabi season, respectively. In the present investigation, the economic injury level worked out to be was 2.42 and 2.09 larvae per plant during kharif and rabi, respectively.
