Whiteflies of Bougainvillea

Disease Information

Whiteflies

DESCRIPTION OF THE PEST

Sap-feeding insects that feed on undersides of leaves. Whiteflies are tiny; the adults resemble white moths. The immature stages look like scale insects.

Symptoms

Infested leaves often have small yellow spots where adults or immature whiteflies have fed. When populations become dense, the leaves become yellow and lower leaves are covered with black sooty mold.

Management

If necessary, spray the shrub thoroughly in mid-summer when adult viburnum whitefly begin to appear. Use thiacloprid (e.g. Bayer Provado Ultimate Bug Killer), acetamiprid (e.g. Bug Clear Ultra) or deltamethrin (e.g. Bayer Sprayday Greenfly Killer) or pyrethrum (considered organic e.g. Py Spray Garden Pest Killer).
