Four field trials of two season studies in two different geographical locations were conducted in the temperate region of Nilgiri District, Tamil Nadu, India. Results revealed that, chlorantraniliprole 18.5 SC @ 10 g a.i. ha-1 and emamectin benzoate 5 SG @ 10 g a.i. ha-1 treated plots were observed more than 90 percent reduction of P. xylostella larval population after two rounds after spray and recorded relatively safer to spider population when compared to other test insecticides. Based on per cent reduction in population of P. xylostella over untreated control, the order of relative efficacy of different insecticidal were, chlorantraniliprole 18.5SC @ 10 g a.i. ha-1 = emamectin benzoate 5SG @ 10 g a.i. ha-1 > indoxacarb 14.5SC @ 40 g a.i. ha-1 = novaluron 10EC @ 75 g a.i. ha-1 = chlorfenapyr 10 SC @ 75 g a.i. ha-1 > thiodicarb 75WP @ 750 g a.i. ha-1 = fipronil 80 WG @ 75 g a.i. ha-1 > chlorpyrifos 20 EC @ 400 g a.i. ha-1. A reduction in the population of spiders in chlorantraniliprole 18.5 SC @ 10 g a.i. ha-1 and emamectin benzoate 5SG @ 10 g a.i. ha-1 treated plots were observed immediately after the application of insecticides. Though there was a sudden decline in the population, it started increasing gradually. Hence, chlorantraniliprole 18.5 SC @ 10 g a.i. ha-1 and emamectin benzoate 5SG @ 10 g a.i. ha-1 will be recommended for the management of P. xylostella in cabbage ecosystem in temperate regions.
