Mealy bugs are off-white in colour and have oval flattened bodies growing to about 3mm long. Waxy strands that resemble legs occur along the sides of the body and some species also have a long “tail.” Normally they leave small cottony masses, their eggs, where the leaves join onto the stem. They like dark places so be sure to check under the leaves and well inside the foliage of a plant regularly. A severe infestation will cause wilting, discolouration and stunted growth of a plant.
Citrus mealybugs have been collected from at least 27 host plant families. Many ornamental plants grown in greenhouses are susceptible to attack including begonia, coleus, amaryllis, cyclamen, and dahlia. Citrus mealybug has been collected on canna, narcissus, and tulip outdoors.
