The Greedy Scale infests a wide variety of ornamental and food bearing plants. In California it is a serious pest on olive trees, where it feeds on stems, leaves, and developing olives. It is also found on acacia, apple, citrus, palms, Ficus, guava, peach, rose, and many other plants. The crawler stage does not feed, but wanders to soft foliage and within a few hours or a few days becomes sessile and begins creating a wax shell. As they molt the previous skin (called the exuvium) is pressed into the growing wax shell, forming a characteristic dot at the center. There may be several generations each year, with all stages present at any one time. The major population growth is during the warm months.
For ornamentals dormant or summer oils may be effective in killing the scales, as well as contact insecticides applied when the first instar crawlers are present. An IGR applied when crawlers are present also may be effective. A systemic applied to the soil can also provide effectiveness in killing the feeding scales. For food-bearing trees a registered insecticide needs to be used as a topical treatment.
