abstract
Field experiment was conducted to determine the extent of damage by Spodoptera litura on cabbage, in Jabalpur, Madhya Pradesh during the Rabi season from Sept., 2017 to March, 2018 at two different locations. The extent of damage by S. litura was recorded with respect to infestation done by larval population. The infestation started on cabbage in second fortnight of November. During the period, average larval population was 0.1 larvae/head which caused 2 per cent of plant infestation. During second fortnight of January, maximum head infestation (54 %) was recorded by average larval population 3.17 larvae/head.
