Ranga Agricultural University, A.P during the year 2011- 12 in a randomized block design with seven insecticidal treatments which were replicated three times and tested against DBM (Plutella xylostella) on cabbage. Efficacy of seven insecticides viz., emamectin benzoate 5 SG at 11 g a.i.ha-1, emamectin benzoate 5 SG at 22 g a.i.ha-1, profenophos 50 EC at 500 g a.i.ha-1, profenophos 50 EC at 1000 g a.i.ha-1, spinosad 45 SC at 100 g a.i.ha-1, bifenthrin 10 EC at 100 g a.i.ha-1 and Bacillus thuringiensis at 5 WP at 25 g a.i.ha-1 as evaluated during Kharif, 2012 against DBM (Plutella xylostella) on cabbage. Among all the insecticides, profenophos (1000 g a.i.ha-1) was found to be the most effective one with a maximum reduction in Plutella xylostella population (70.20%), followed by bifenthrin 10 EC at 100 g a.i.ha-1 (68.18%).
