Citrus Mealybug

Planococcus citri (Risso) (Hemiptera: Pseudococcidae)

A small, soft-bodied insect that appears to have been rolled in flour due to its white, waxy coating. A pest of citrus and ornamental plants since the 1800s, it damages plants by sucking sap and secreting honeydew that supports sooty mold growth.

Peak Season: Active year-round in warm climates, primarily greenhouse pest in northern regions
Mealybugs showing characteristic white waxy coating and egg masses

Identification & Symptoms

What to Look For

White, cottony masses on stems, leaves, and branch crotches
Plants appear covered in white fluffy material
Yellowing and stunting of infested plants
Honeydew excretion creating sticky surfaces
Black sooty mold growing on honeydew deposits
Distorted growth and premature leaf drop
Plant death if pest is not controlled

Potential Damage

Sucks plant sap, weakening host plants
Toxic saliva causes distorted growth
Honeydew excretion attracts sooty mold
Heavy infestations can kill plants
Cottony wax secretions disfigure plants
Reduced plant vigor and aesthetic value

Lifecycle

Wingless females lay hundreds of eggs in fluffy white ovisacs. Crawlers hatch within a few days and begin feeding immediately. Females cannot fly but crawl short distances; immatures can be blown by wind. Males are small, winged insects. Multiple generations possible in warm climates.
