Effect of eco-friendly pesticides on mortality, growth and development of Spodoptera litura (Fab.) in laboratory condition
Rabin Mandi and Aniruddha Pramanik
The present experiments were conducted at IPM Laboratory, Directorate of Research, Bidhan Chandra Krishi Viswavidyalaya, to find out the efficacy and toxicity of some eco-friendly pesticides against cabbage borer, Spodoptera litura (Fab.). Among the treatmentsmaximum mortality (91.25%) was noticed in diflubenzurn + deltamethrin 22% SC @ 0.022%at 7th day of observation but at par with that of (91.13%) abamectin 400FS@ 0.02%. The highest growth index (5.00) was noted in untreated control as compared to the lowest growth index (1.03) which was observed in diflubenzurn + deltamethrin 22% SC @ 0.01%. The lowest larval pupal index (1.24) and lowest survival index (0.33) of Spodoptera litura was obtained in case of Bacillus thuringiensis @ 0.1%.From this study it can be said that among five different pesticides, Bacillus thuringiensis, revealed higher susceptibility to Spodoptera on the basis of the percent pupation and adult emergence.
