Abstract

To undertake the present study the field experiment was conducted at research farm of entomology section at college of agriculture, Badnapur during Rabi season of 2023-2024. Under present investigation the reaction of eight varieties of cabbage were recorded against Plutella xylostella L. pest. The experiment was conducted in three replications under natural condition without application of Insecticide and weedicide. The reaction was recorded from 15 days after sowing to till harvesting, none of the varieties found immune to Plutella xylostella L. attack however the present study revealed that the inception of Plutella xylostella observed during standard meteorological weeks and the population Plutella xylostella L. larvae ranged between 2.00 to 3.33larvae/plant. The lowest population of Plutella xylostella was recorded on Saint (2.00 larvae/plant) followed BC-79 (2.50 larvae/plant), Doller (2.70 larvae/plant), and referred as tolerant Varieties. Moderately infested entries were Atulya (2.83 larvae/plant) followed by Varun (3.00 larvae/plant). Green rock (3.17 larvae/plant) The maximum population observed varieties were, Elite (3.27larvae/plant), Videshi (3.33larvae/plant).
