The Pest: Whitefly


First Signs: Tiny, pure white "moths" resting on leaf surfaces. When the leaves of the plant are disturbed, these moth-like white flies quickly flutter up, then settle back down onto plants.
Leaves may appear shiny with honeydew. A magnifier reveals clear-white "scales" (the pupae) on the undersides of leaves. All life stages of the Whitefly literally suck the water out of plant leaves.
Most Common Species:
Greenhouse Whitefly & Sweet Potato Whitefly. It's so difficult to be certain which species you have that we advise either consulting your county agent to be sure, or simply widening your predator strategy to cover both species - it's not uncommon to have both pests together.
