Abstract: Experiments were conducted to determine the effective concentration of three insecticides i.e thiamethoxam (Actara, 25%WG),
diafenthiuron (Pegasus,50%WP) and clothianidin (Dantop,50% WDG ) against nymphal stages of whitefly under laboratory condition.
Probit analysis was done with the observed values of mortality against concentrations of insecticides. From the analysis LC90 values of
these three insecticides were worked out as 0.0131% for thiamethoxam, 0.0635% for diafenthiuron and 0.0046% for clothianidin.
