Abstract
Field experiment was conducted to determine Seasonal Abundance of Diamondback Moth Plutella Xylostella (Lepidoptera: Plutellidae) On Cabbage Crop (Brassica oleracea var. capitata L.), in Jabalpur, Madhya Pradesh during the Rabi season from Sept., 2017 to March, 2018.First appearance of the P. xylostella was observed when the crop age was about 82 days i.e. first week of December (49th SW). Pest was present on the crop during the vegetative stage and remained available up to harvesting of the crop i.e. 11th standard week. Temperature maximum, temperature minimum and temperature average showed significant positive correlation (r= 0.58*, 0.58*, 0.63** respectively) and morning and average relative humidity showed significant negative correlation (r=-0.63**, -0.57*) with larval population.
