White mite — Arecanut

Symptoms

White mites congregate on the lower surface of the arecanut leaflets and suck the plant sap. This feeding causes small yellow or white speckles (stippling) to appear on the upper surface of the leaves. As the population multiplies, they spin fine, silken webs across the under-surface of the leaf. In cases of severe infestation, the leaves lose their green color, turn pale yellow, dry up, and eventually wither, drastically reducing the palm's ability to photosynthesize.
