Mealybug

Natural Habitat

Found worldwide in warm, moist climates; commonly infests indoor houseplants, greenhouses, and outdoor crops like citrus, grapes, and ornamental plants.

Diet & Feeding

They feed on plant sap by piercing plant tissues with their stylets, excreting a sticky substance called honeydew as a byproduct.

Behavior Patterns

Mealybugs tend to congregate in protected areas of plants, such as leaf axils and undersides of leaves. They move slowly and produce a protective white, waxy, cotton-like coating. They reproduce rapidly in warm conditions.

Risks & Benefits

Risks: Major agricultural and horticultural pests that can stunt plant growth, cause leaf yellowing, and transmit plant diseases. The honeydew they secrete promotes the growth of black sooty mold. Benefits: Generally considered pests with no significant direct benefits to humans, though they serve as food for some predatory insects like ladybugs.
