Small, white flying insects with sedentary larval stages (scales) which feed on plant sap, weakening the plants. The scales, which produce copious amounts of honeydew, are difficult to see, being a light creamy colour. 


Crops grown outdoors are not normally attacked (but may be attacked by other types of whitefly), but indoor crops are vulnerable, with tomatoes, cucumbers, fuchsias and soft-leaved ornamentals being examples of the most susceptible hosts.

Control with Encarsia parasite. Encarsia parasite are tiny parasitic wasps which lay their eggs in the whitefly scale, the Encarsia larva kills the scale which turns black before a new adult Encarsia emerges. Introduce as soon as whitefly are seen. Repeat applications are advisable if the problem is severe. Needs temperatures of 15 – 18 degrees for a few hours each day.

Agralan whitefly killer is safe to use with biological control, spray first to reduce pest numbers.
