Evaluation of novel insecticides and their persistency against diamondback moth, Plutella xylostella Linn.

N Teja, V Sunitha, V Ramesh Babu and J Satyanarayana

Toxicity and persistency of different novel insecticides with diversified mode of insecticidal action was determined on the basis median lethal concentration (LC50) values against third instar larvae of diamondback moth, Plutella xylostella under laboratory conditions. The median lethal concentration LC50 values (%) deduced for the test insecticides viz., emamectin benzoate, chlorantraniliprole, flubendiamide, fipronil and chlorfenapyr were 0.0028, 0.0328, 0.0267, 0.0172 and 0.0219, respectively with emamectin benzoate to be most lethal, followed by fipronil, chlorfenapyr, flubendiamide and chlorantriniliprole. The persistency of the test insecticides from 24 hours after treatment based on PT values revealed that chlorantraniliprole possessed highest persistence toxicity (856.52) followed by flubendiamide (649.61) > chlorfenapyr (606.6) > fipronil (549.89) > emamectin benzoate (519.90).
