Seven field populations of whitefly Bemisia tabaci Genn. (Hemiptera: Aleyrodidae) were collected from Qalubia, Sharkia, Dakahlia, Gharbia, Monofia, Behira and Kafr El-Sheikh Governorates, Egypt, during season 2018. Development of resistance in insect populations against insecticides [pyrethroids (α-cypermethrin and etofenprox), organophosphates (malathion and primiphos-methyl), carbamates (carbosulfan and methomyl) and neonicotinoids (acetamiprid and thiamethoxam)] were evaluated for determining the slope response line, LC50 values and resistance ratio (RR) in laboratory tests. The RR in different governorates population were in ranges from 1.42 to 185.78 fold for pyrethroids, 0.80 to 9.63 fold for organophosphates, 0.38 to 44.98 fold for carbamates and 0.19 to 166.66 fold for neonicotinoids, respectively, comparing with Gharbia which showing the lowest LC50 values. The activity levels of detoxifying enzymes viz, acetylcholinesterase (AChE), glutathione -Stransferase (GST) and Carboxylesterase (CarE) were determined in insect populations of different governorates, compared to Gharbia as well as the control.
