Control Strategies

Grayish mealybugs with distinct tail filaments, often on stems, leaf undersides, and fruit of citrus, grapes, and ornamentals. Live-bearers, so populations can rise quickly without obvious egg masses.

Long waxy caudal filaments distinguish them from shorter-tailed species; colonies appear flat and dusty.

Organic Control Methods

Prevention

Quarantine new plants; control ants that defend mealybugs.

Biological Controls

Same predators and parasitoids as other mealybugs—Anagyrus and Acerophagus wasps where present.

Cultural Practices

Open canopy for air movement; avoid over-fertilization.

Mechanical & Physical

Wipe stems and fruit with soapy cloth on small holdings.

Organic Sprays

Repeated soap, neem, or horticultural oil applications timed to crawler emergence.
