Toxicity of new molecules of insecticides against diamond backmoth, plutella xylostella l. infesting cabbage

Among the various newer molecules of insecticides tested for their toxicity against various larval instars revealed that flubendiamide was found to be most effective, followed by, indoxacarb, spinosad, and fipronil. The LC50 values recorded for flubendiamide 0.009, 0.009, 0.010 and 0.013, indoxacarb 0.013, 0.014, 0.015 and 0.017, spinosad 0.029, 0.030, 0.036 and 0.060, and fipronil 0.117, 0.120 0.136 and 0.156 µg/L, respectively against first, second, third and fourth instar larvae of P. xylostella. The flubendiamide exerted more effective chemical in causing mortality of third instar larvae of P. xylostella. The treatment with indoxacarb, spinosad, and fipronil were in the order of their efficacy.
