Landscaping - Insects & Diseases
Whiteflies are economically important insects on ornamentals grown in the greenhouse. Although these pests are most serious in the greenhouse, whiteflies may also attack ornamental plants grown outdoors. Some of the preferred woody ornamental hosts include barberry, redbud, Fucshia, honeylocust, black locust, Hibiscus, Lantana, coffeeberry, rose and Jerusalem cherry.
