Abstract: Whitefly (Bemesia tabici G.) population in treated plots was observed significantly lower than the untreated control. Among four insecticides diafenthioron (Polo 500 SC) @ 250 grams per hectare active ingredient was found the best one that gave 76 percent mortality of Whitefly population. The endosulfan (Thiodan 35EC) @ 875 grams active ingredient per hectare was closely following the diafenthioran with 72 percent mortality.
