Mealy Bug — Arecanut

Symptoms

clusters of small, oval insects covered in a white, powdery or cottony wax. They congregate in the leaf axils, on the spathes, and heavily infest the tender nut bunches. As they continuously suck sap, the leaves and developing bunches turn yellow and lose vigor. Mealybugs also excrete a sugary substance called "honeydew," which coats the plant parts and leads to the growth of black sooty mold, severely reducing the palm's ability to photosynthesize.
