Scales are preyed upon by small parasitic wasps and many predators, including certain beetles, bugs, lacewings, and mites. Preserving (conserving) parasites and predators (such as by controlling pest-tending ants) may be enough to bring about gradual control of certain scales as natural enemies become more abundant.

Both sexes pass through three growth stages before sexual maturity. Calif. Agric. Both males and females go through two immature stages before becoming adults. High scale densities may reduce the growth rate of the tree and can cause needles, shoots or entire branches to die. When a new flush of growth occurs on the host plant, the more mature scales will often migrate to the new growth at the top of the plant.

Several pests can cause problems for ficus trees, including the armored dictyospermum scale, black scale and green shield soft scale. It's about 6m tall and 6m wide. For species with multiple generations, all scale life stages may be present throughout the year in areas with mild winters. Introduction. Scale sounds and looks a lot like a plant disease, but the term actually refers to infestation by any one of more than 7,000 species of tiny sap-sucking insects. Settled nymphs may spend their entire life in the same spot without moving as they mature into adults. 3), hatch from eggs over a period of 2 to 3 weeks and crawl to and settle on leaves, twigs and stems of host plants thereby spreading the infestation. Wax scales injure plants by removing large quantities of plant sap. Large amounts of a sticky, sugary liquid, called honeydew, is secreted by these scale insects and is colonized by a fungus called sooty mold, and causes infested plant parts to turn black and become unsightly. The shell also makes it difficult to use a pesticide because it has trouble reaching the insect inside. Apply with a spray bottle or garden sprayer until all the leaves are dripping.
