Scale eggs are laid under the females body, so they are shielded by the protective outer coating of the mother insect. UC Statewide IPM Program. It's about 6m tall and 6m wide. The best approach is to put the rubbing alcohol directly on the scale bugs using a cotton swab. Release commercially available parasites and predators. First generation scales settle on leaves, but On the C. More than one application per growing season may be needed, especially if the targeted pest has more than one generation a year. Geisel, P., and E. Perry. Because ants attack and feed on scale parasites and predators, control ants if they are tending scales. Nat. Courtesy of NYBG Plant Information Service. However, no natural enemies (pathogens, parasites, predators) have been observed to provide biological control of Florida wax scales in Texas. For example, rinse small plants when foliage becomes dusty. The crawlers disperse away from the adults to find new feeding sites. University of California Integrated Pest Management. 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. Promote plant vigor and health by properly selecting preparing planting sites, and providing optimal watering and fertilization. There are several things you can do to prevent populations of Hard Scales Insects building up to damaging levels (seeHow To Prevent Scale Insects Appearing). There are two to six generations per year, depending on the climate. Adult males are rarely seen and are tiny, delicate, white to yellow insects with one pair of wings and a pair of long antennae. Publ. 1e). Authors: J. N. Kabashima, UC Cooperative Extension, Orange and Los Angeles Counties; and S. H. Dreistadt, UC Statewide IPM Program, Davis. No description of males is readily available, but they are likely to be tiny, gnat-like adults. Adults of predatory bugs, lacewings, lady beetles, and parasitic wasps live longer, lay more eggs, and kill more scales when they have plant nectar or pollen and insect honeydew to feed on. Purdue University Extension, Scale Insects. You may effectively address minor scale infestation on small ficus trees by rubbing each scale with a cotton swab soaked with rubbing alcohol. They then settle down to feed either on leaves, twigs or small branches. Although baits require users to be patient, they can be much more effective than sprays. The Spruce uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Regulatory Hort. Adult female Red Scales are reddish-brown, circular and about 2 mm in diameter. Products include bright yellow cards that produce distinct blue dots upon contact with honeydew or water. Introduction.

Sanitation and pruning will reduce initial pest density and opens the canopy for improving spray coverage. Entomol. Adult female Wax Scales are generally globular in shape and covered in waxy secretions. Res. Nymphs are orangebrown with long hairs and covered with cottony secretions. The active ingredients of pyrethroid insecticides all end with "-thrin.". 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. The actual insect body is underneath the cover; if you remove the cover, the insect body will remain on the plant. Gumtree Scales are a bit different in that females encase themselves in a globular sac, and they too produce honeydew. Cover the bark and foliage as completely as possible. Late spring and summer are also the times to spray avocado, citrus, and many other broadleaf evergreens. Food Agric. Keep a close eye for several weeks to make sure no new scale appears on the plant. Sevin and pyrethroids labeled for residential landscape use are readily available in most big box stores, plant centers, and nurseries. This can be quite laborious in an outdoor garden, however, so you can also fill a garden sprayer or spray bottle with a mix containing one part rubbing alcohol to seven parts water. Hard Scales produce a separate waxy cover under which the insect feeds, but do not produce honeydew. Res. Quick search tells me it might be barnacle scale. Planting a variety of fragrant, flowering ornamental plants and herbs near the ficus helps to attract beneficial scale predators to the area. Botany (Taxonomy, Nomenclature and Morphology). Even very high populations of oleander scale are harmless to most plants, but cycad scale warrants control because it causes serious damage and can kill sago palms.

In North Carolina, gardenia is the most common host. To obtain adequate control, thoroughly wet the infested plant parts with spray, typically shoot terminals and the underside of leaves. Neem oil may destroy an early rust infestation, but removing fallen debris will often prevent fig rust from taking root. This is likely the case with barnacle scales, too. Publ. 2021 For noncommercial purposes only, any Web site may link directly to this page. The eggs hatch into crawlers, which disperse through the plant or are carried by the wind to other plants. At least one to two minutes of disinfectant contact time between contaminated uses is generally required. She's also an author of three gardening books, a plant photographer, public speaker, and a former Cornell Cooperative Extension Horticulture Educator. If most or all of the scales inspected are dead or being parasitized, additional control is generally not warranted and the ficus will recover with good cultural care. Thoroughly cover with spray the plant parts where scales occur, typically on twig terminals and the underside of leaves. Orange crawlers hatch from the eggs and disperse over the tree.

Flint, M.L., and K. Windbiel-Rojas. It is important to correctly distinguish the scale family (e.g., armored versus soft scale) and often the particular species of scale to determine whether control is warranted; and if so, what methods and timing of control action are effective. The authors are grateful for reviews of earlier versions of this manuscript by Carlos Bogran and Scott Ludwig. Fla. Dept. Inspect plants to determine whether female scales, nymphs, honeydew, sooty mold, or ants and other pests are present. Male nymphs are oval and paler. Scales hatch from an egg and typically develop through two nymphal instars (growth stages) before maturing into an adult. On holly, Florida wax scales are easily spotted because most of them colonize the upper leaf surface. With foliage spraying and soil application, when possible, wait until nearby plants also have completed flowering as spray can drift onto nearby plants or their roots may take up some of the soil-applied insecticide. Trace back trail-making ants to locate colonies of the honeydew-producing insects. Imidacloprid controls European elm scale and most soft scales but does not control cottony cushion scale and most armored scales. Fig 2.

Look for Scale Insects on leaf surfaces, twigs and fruit. Rhyzobius lophanthae has a reddish head and underside and a grayish back densely covered with tiny hairs. If you catch the problem early enough, pruning out the infested stems could alleviate the problems. Effective, slow-acting bait insecticides work over a period of days so that before ants die they will spread the toxicant among many other ants during food sharing. Each plate has a small, darker, spot usually surrounding a tiny button of wax. 1.

Produced by University of California Statewide IPM Program. Depending on the scale species and the extent to which biological control has been disrupted, it will take several months of conservation efforts (such as controlling ants and dust and avoiding application of persistent insecticides) or until the next season or longer before scale populations are reduced by biological control. University of California Statewide Integrated Pest Management Program: Ficus, Fig, Indian Laurel, Laurel FigFicus spp. Do not implant or inject into roots or trunks more than once a year.
