Abstract:

The varietal screening of S. oryzae was studied on the rice grain and it was revealed that the minimum number of adult emergence was found in variety Swarna (3.33 adults) whereas variety MTU-1001 was found to be tolerant against S. oryzae with less per cent of grain damage (2.66%) and weight loss (1.00%). While the variety Dubraj Selection -1 was found highly susceptible to this pest in accordance to highest number of adult emergence (21.65 adults), maximum percent of grain damage (8.33%) and weight loss (6.66%), respectively.
