Title : Effect of Different Insecticides against White fly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) in Greengram

Abstract :

Experiments were conducted during three consecutive Kharif seasons to study the effect of commercially available insecticides formulations, Acetamaprid 20 % SP (1.0 gm/ litre of water), Imidacloprid 17.8 % SL (1.0 ml/ lit.), Quinalphos % 25 EC (2.0 ml/ lit.), Thiomethoxam 25 % WG (1.0 gm/ lit.), Neem oil 2% (20 ml/lit.), Karanj oil 2% (20 ml/lit.) against the White fly, Bemisia tabaci in Greengram. The descending order of most effective insecticides was: Imidacloprid >Thiomethoxam> Acetamaprid. The maximum population reduction over control was found after seven days of applying the second spray at 15 days of interval viz., 75.09 and 68.86 per cent due to Imidacloprid, Thiomethoxam, respectively the year 2015. A similar trend was found in the year 2016 and 2017. Thus, Imidacloprid 17.8 % SL was most effective against the White fly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae).
