Abstract

Diamondback month, plutella xylostella (L) , is a serious pest of cauliflower in Pakistan and has developed resistance against various insecticide groups. Therefore, the studies were carried out to monitor their resistance factor form different areas of Punjab against thirteen insecticides having different mode of actions to develop strategies for its management. Cypermethrin gave 7.0-54.0, deltamethrin 4.4-37.3, bifenthrin 2.4-28.8, lambdacyhalothrin 2.5-34.5, chloroyrifos 11.6-98.0, triazophos 7-68.4, profenofos 1.4-136.1, endosulfan 7.9-92.2, spinosad 1.1-12.1, indoxacarb 1-38., emamechin benzoate as compared to the susceptible strain (laboratory reared). Seasonal variations gave different LC50 values among three populations collected at different times of cropping season . It gave 2383.6 and 0.08, 5248.6 and 0.07,1795.1 and 0.05 maximum-minimum values to chlorpyrfos and emamectin benzoate in 1st ,2nd and 3rd collected populations respectively. Five new chemistry chemical i.e spinosa indoxacarb, lufenuron, emamectin benzoate and abametin were use for their efficacy at different intervals. It proved spinosad, emamectin benzoate and abamectin most effective against all instars as compared to the indoxacarb and lufenuron.
