Investigations were undertaken from 1999-2003 at Institutes farm of Central Institute for Subtropical Horticulture, Lucknow, India and result indicated that the incidence of Deudorix isocrates was at its peak on cv. L-49 in the month of August in rainy crop, while in winter crop it was more during November/December. The incidence ranged from 3.0 to 38.0 per cent during these periods. Losses in fruit weight were found directly proportional to the extent of infestation by the borer. | |
