摘　　要：The whitefly is well-known as a serious pest on many economic vegetable crops. It feeds by absorbing plant sap which includes many important nutrients for plant,＇;. An experiment was carried out to investigate the effect of whitefly, B. tabaci （Gennadius）, infestation on the micronutrients; Manganese, Zinc, Copper and Molybdenum, in three plant varieties; cantaloupe （Cucumis melo L.）, cucumber （Cucumis sativus L.） and zucchini （Cucurbita pepo L.） that were planted in a greenhouse at the Agricultural Research Station in Hada AI Sham, north east of Jeddah in Saudi Arabia. Results of this investigation showed that, in general whitefly infestation reduced micronutrients content in plants. Mean content of total micronutrients in each of infested cucumber and zucchini were less than control plants significantly, but the infestation did not vary total micronutrients content in cantaloupe significantly. Feeding of the whitefly reduced mean content of each Zinc and Molybdenum in infested plants significantly, but did not vary Manganese and Copper content significantly.
