Whitefly (Aleyrodidae)

is a sap-sucking insect that attacks sugarcane, particularly under warm and humid or relatively dry conditions. It is mainly found on the underside of leaves, where adults and nymphs suck plant sap. Heavy infestation can cause yellowing, weakening and premature drying of leaves, reducing photosynthesis and plant growth. Whitefly also produces honeydew, which can promote the development of sooty mold and further reduce photosynthetic activity. Severe infestation may ultimately affect cane growth, quality and yield. In Pakistan, whitefly is recognized as one of the important insect pests of sugarcane. Pesticide/Control: Whitefly should be managed according to the registered label and economic threshold level. Insecticides containing active ingredients such as Imidacloprid and, where specifically registered for the target crop/pest, Chlorpyrifos may be used. Different companies may market the same active ingredient under different brand names and formulations, such as Imidacloprid 20% SL/200 g/L or Chlorpyrifos 40% EC/400 g/L. Therefore, the brand name is less important than checking the active ingredient, formulation, crop/pest registration and label-recommended dose before application.
