Abstract:

The synergistic action of insecticides (endosulfan, monocrotophos, methomyl, cypermethrin and indoxacarb) with seed oils (mahua oil, neem oil, pongamia oil and sesamum oil) against field populations of S. litura was studied in the Department of Agricultural Entomology, University of Agricultural Sciences, Bangalore. All the seed oils at 0.1% exhibited varying levels of synergism with five insecticides against the third instar larvae of S. litura. The toxicity of endosulfan was enhanced to the highest degree by pongamia oil. The neem oil synergised the toxicity of monocrotophos and methomyl to a greater extent. Similarly, sesamum oil exhibited pronounced synergism with cypermethrin. The toxicity of the oxadiazine compound, indoxacarb was synergised to a greater extent by neem oil, closely followed by Pongamia oil. By looking into the degree of synergism, the toxicity of endosulfan increased by 12.98- and 10.65- folds by Pongamia oil and neem oil, respectively. Similarly, the toxicity of methomyl was synergised to an extent of 3.27- fold by Pongamia oil. The seed oils of sesamum and neem synergised the toxicity of cypermethrin and indoxacarb by 7.61- and 1.66- folds, respectively.
