Scale insect — Arecanut

Symptoms

Appear as tiny, flat, or slightly raised waxy bumps (scales) firmly attached to the lower surface of leaflets, leaf stalks, and sometimes directly on the arecanuts. Because they remain in one spot sucking sap, localized yellow spots (chlorosis) develop around their feeding sites. In severe cases, the entire leaf turns yellow, dries up prematurely, and the palm's overall growth is stunted
