Do not spray oystershell or olive scales during the dormant season because susceptible stages of these species are not present during winter. Diamond scale, which infests palms, is actually the fruiting bodies of a blackish fungus (Phaeochoropsis neowashingtoniae). Some species of bark lice (Psocidae) are associated with sooty mold. Soft scales, family Coccidae, grow up to 14 inch long and have a smooth, cottony, or waxy surface. Color photographs for 200 scale species and detailed discussion of these and others are available in the California Department of Food and Agriculture publications by Gill listed in References. For more information see the California Department of Pesticide Regulation website. Insecticides differ in their effectiveness for certain scale types. Most immature soft scales retain their barely visible legs and antennae after settling and are able to move, although slowly. Hard Scale Insects dont produce honeydew, so you wont have the added problems of ants and sooty mould to deal with if you find them on your plants. The best approach is to put the rubbing alcohol directly on the scale bugs using a cotton swab. Several pests can cause problems for ficus trees, including the armored dictyospermum scale, black scale and green shield soft scale. Repetition and consistency are the key to success. Spraying your plants with horticultural oil is effective in late spring just before the leaves unfurl. Every day a dozen leaves turn yellow and fall off. Calif. Agric. Pest Notes: Sycamore Scale. It's about 6m tall and 6m wide. Soft scale is covered with a protective waxy substance and is somewhat easier to kill than hard/armored scale. PDF: To display a PDF document, you may need to use a Pest Notes: Black Scale. Often the most important natural enemies of scales are parasitic wasps, including species of Aphytis, Coccophagus, Encarsia, and Metaphycus. Soft scale insects attack plants by Both sexes pass through three growth stages before sexual maturity. Courtesy of NYBG Plant Information Service. Mature female Soft Brown Scales are flat, oval, about 4 mm in length, and a greenish-brown colour mottled with brown spots. The Soft Scale Insects of Florida (Homoptera: Coccidea) in Arthropods of Florida and Neighboring Land Areas Vol. Products include bright yellow cards that produce distinct blue dots upon contact with honeydew or water. Scale insects typically adhere to the stems, branches, and sometimes the leaves of plants to feed on sap, and they have a shell-like bump appearance, which sometimes causes them to be mistaken for a fungal or bacterial disease. Cottony cushion scale, European elm scale, soft scales, and certain other scales secrete sticky honeydew. leaves (Image courtesy of Elise Dando), Image above: Fig Wax Scale (Ceroplastes rusci) on magnolia leaf (image courtesy of Elise Dando), Image above: Heavy infestation of White Louse Scale (Unaspis citri) on a citrus tree trunk (Image courtesy of Elise Dando), Image above: Red Scale (Aonidiella aurantii) on lemon fruit (Image courtesy of Elise Dando), Image above: Soft Brown Scale (Coccus hesperidum) Scale (central in image) with exit hole made by a parasitic wasp (Image courtesy of Elise Dando), 2023 Yates, a division of DuluxGroup (Australia) Pty Ltd. Red Scale All varieties of citrus and other fruits including fig, olive and grape; ornamentals such as ivy, passionfruit and rose; weeds including fat hen and Bathurst burr. Adult female Wax Scales are generally globular in shape and covered in waxy secretions. Oakland: Univ. Honeydew drippings from plants can be efficiently monitored using water-sensitive paper, which is commonly used for monitoring insecticide droplets and calibrating sprayers. Crawlers can be spread to other trees by wind or on the feet of birds. With trunk injection and implantation it is difficult to repeatedly place insecticide at the proper depth. 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. Soft Scales and Cottony Cushion Scales dont have a separate covering like hard scales, but the upper surface of their bodies is toughened with protective mealy secretions. 1998. Fig 3. For species with multiple generations, all scale life stages may be present throughout the year in areas with mild winters. Trace back trail-making ants to locate colonies of the honeydew-producing insects. A barrier band about 2 to 6 inches wide should be adequate in most situations. Staff-only pages Apply with a garden sprayer. For example, rinse small plants when foliage becomes dusty. However, their biology may not be that precisely synchronized, as nymphs have been photographed on leaves and stems well into early winter. We appreciate Chris Fox for providing suggestions of non-host ornamental plant alternatives to hollies. 7409. Other plant-based pesticides can also be successful. Statewide IPM Program, Agriculture and Natural Resources, University of California Avoid applying sticky material to horizontal surfaces where birds may roost. In Texas, the authors have observed infestations on other plants including elephant ear, golden Euonymus, honeysuckle, pomegranate, winged elm and Virginia creeper. Publ. Wax scales injure plants by removing large quantities of plant sap. If the infestation is already too far advanced, it may be hard to save the plant. The Scale Insects of California Part 1: The Soft Scales. Three parasitic wasp species (Coccophagus lycimnia, Scutellista cynea and Metaphycus eruptor) have been reported for Florida wax scales in some parts of the U. S. (Hamon & Williams 1984). Keep the plant well away from other plants until the problem is eradicated. Nat. At this point, the nymphs have legs and are actively crawling to find new spots to attach and feed. University of California Statewide Integrated Pest Management Program: Scales, New Mexico State University: Scale Insects on Ficus. Nymphs are orangebrown with long hairs and covered with cottony secretions. Female European fruit lecanium scale, one overturned to reveal eggs. It's about 6m tall and 6m wide. Most species of armored scales have several generations a year and overwinter primarily as first instar nymphs and adult females. new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0], You will have to keep an eye out so as to remove all those hard scale where they appear, again, usually on the stems. The oil is usually emulsified to make it easier to spray. To obtain adequate control, thoroughly wet the infested plant parts with spray, typically shoot terminals and the underside of leaves. The most common types that occur in home gardens are several species of Hard Scales in the family Diaspididae, and several species of Soft Scales of the family Coccidae. After the insects have died, you can hose them off as well as any sooty mould they may have promoted. Do not mix oil with chlorothalonil, sulfur, and certain other fungicides; and do not apply oil within 3 weeks of an application of sulfur-containing compounds, such as wettable sulfur.

She holds a Bachelor of Arts in urban and regional studies. You will need to be extremely diligent about controlling or removing scale when it infests indoor plants. Each instar can change greatly as it ages, so many scales appear to have more than two growth stages. Armored scales and soft scales are the most common types (or families). Wrap the ficus trunk with a thin band of tree wrap or masking tape and coat this wrap with a sticky material designed to Band tree trunks with horticultural glue to prevent ants climbing up. Res. Flint, M. L., and S. H. Dreistadt. Certain home-use products can easily be drenched into soil around the tree trunk using the mix-and-pour method. NC State University and NC Crawlers settle down and begin feeding within a day or two after emergence. Adult and early star-like immature stages. A band of horticultural glue is all you need to prevent ants climbing into trees. 1984. There are many scale insect species that infest ornamental landscape plants. Settled nymphs may spend their entire life in the same spot without moving as they mature into adults. Individuals who use agricultural chemicals are responsible for ensuring that the intended use complies with current regulations and conforms to the product label. Some gardeners put their ficus tree outdoors in summer to help control problem pests and improve the vigor of the plant as well. The crawlers moult to the second nymph stage and become sedentary like the adult females. Populations of some scales can increase dramatically within a few months when the weather is warm, and honeydew-seeking ants protect scales from their natural enemies. Calif. Agric. 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. If the scale produces honeydew, this sticky excrement, sooty mold, and the ants attracted to honeydew can annoy people even when scales are not harming the plant. Mix the concentrate in a sprayer and apply Boric acid, fipronil, and hydramethylnon are examples of insecticides used in ant baits. As always, test on a small area first, since some plants are more sensitive than others. To control most scales overwintering on deciduous woody plants, thoroughly spray the bark of terminal shoots with oil during winter. Except for crawlers and adult males, armored scales lack obvious appendages and spend their entire life feeding at the same spot. This barnacle scale shows its plates of wax outlined by narrow depressions. The alcohol alone should kill the scale, but the dead insects will remain on your plants and make it difficult for you to scout for new infestations. There are hundreds of species of insects across several families of the superfamily Coccoidea that are known as Scale Insects. Flint, M.L., and K. Windbiel-Rojas. Scale insects are very adept at protecting themselves at most stages of their life cycle. Res. Yellow patches on leaves around feeding scales. UC Statewide IPM Program. More than one application per growing season may be needed, especially if the targeted pest has more than one generation a year. Eggs hatch into tiny crawlers (mobile first instar nymphs), which are yellow to orangish in most species. Food Agric. Repeat every two to three days until the problem insects are eradicated. Plants are not harmed by a few scales and even high populations of certain species apparently do not damage plants. Soft scales include black scale, brown soft scale, Kuno scale, lecanium scales, and tuliptree scale. Infested plants appear water stressed, leaves turn yellow and may drop prematurely, and plant parts that remain heavily infested may die. Nymphs pass through a couple of moults before becoming adults. Change and inspect the tape weekly. (PDF) Sacramento: Calif. Dept. The dense, rounded canopy and gracefully drooping branches of weeping fig made it quite popular as a landscape tree until recently. The Spruce uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Thorough spray coverage is especially critical when treating armored scales and oak pit scales as these scales are generally less susceptible to pesticides than soft scales. Sanitation and pruning will reduce initial pest density and opens the canopy for improving spray coverage. A valid pesticide applicators license is required for their possession and use. 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. Authors: J. N. Kabashima, UC Cooperative Extension, Orange and Los Angeles Counties; and S. H. Dreistadt, UC Statewide IPM Program, Davis. Keep a close eye for several weeks to make sure no new scale appears on the plant. However, scale insects vary greatly in color, shape, and size. The authors are grateful for reviews of earlier versions of this manuscript by Carlos Bogran and Scott Ludwig. In comparison with systemics that are sprayed onto foliage, products labeled for soil drench or injection, or for trunk injection or spray minimize environmental contamination and may be more effective than contact insecticides. Apart from biological control (seeNatural Enemies), the mainstay of Scale Insect control is the application of horticultural oils. --- However, conserving resident natural enemies is a more efficient and longer lasting strategy than buying and releasing beneficials in gardens and landscapes. N.C. Infested plants sometimes turn almost black with sooty molds and plant growth is stunted. Rhyzobius lophanthae has a reddish head and underside and a grayish back densely covered with tiny hairs. A large rear plate has three buttons. When populations are high, trees appear to be flocked with white specks (Fig. Visually inspect plants regularly for early signs of infestation. Pest Notes: Ants. Oakland: Univ. Produced by University of California Statewide IPM Program. There is a longer time delay between soil application and insecticide action. Retail Nursery and Garden Center IPM News. Flint, M. L. 1998. If a large proportion of scales are dead or parasitized by natural enemies, consider delaying a treatment decision and monitor the population again later before deciding whether to apply pesticide. Before applying insecticide, examine a portion of the scales to determine whether they are dead or parasitized as described below; for example, they fail to exude fluid when squished. Avoid creating dust because it interferes with natural enemies. The eggs hatch into crawlers, which disperse through the plant or are carried by the wind to other plants. We answer questions in the order received. Immature fruit are dried up and may remain on the tree. Honeydew monitoring is useful where there is a low tolerance for dripping honeydew, when managing many trees, such as along city streets or in parks, and on tall trees where the honeydew-producing insects may be located too high to easily observe. Unlike the hard scales, Florida wax scale nymphs will often move from one location to another. University of California Statewide Integrated Pest Management Program: Ficus, Fig, Indian Laurel, Laurel FigFicus spp. Be sure to obtain current information about usage regulations and examine a current product label before applying any chemical. Transparent double-sided sticky tape can be used to effectively time a foliar insecticide application. Mix the concentrate in a sprayer and apply thoroughly over the leaves or affected plant parts. The wax scales are globular in shape and coated with a heavy layer of wet-looking white, beige to pinkish or gray wax. Hard Scales produce a separate waxy cover under which the insect feeds, but do not produce honeydew. 1e). The eggs hatch into crawlers that initially settle along the mid-veins on the underside of leaves, but older nymphs migrate to twigs and branches where they remain. See our Home page, or in the U.S., contact your local Cooperative Extension office for assistance. Treatment suggestions for very large tree? The name White Louse Scale is derived from infestations of male nymphs. https://www.daleysfruit.com.au/forum/barnacle-scale-on-fig-trees Identification of E. scitula. Nymphs of some species can move slowly, such as soft scales that feed on deciduous hosts and move from foliage to bark in the fall before leaves drop. When removing individual adult female scales from leaves at certain times of the year, hundreds of eggs will pour out of their body cavities (Fig. Scale insects in the garden can be combated in a number of ways, the best of which involves prevention or removing infested plant material before the insects can spread. Scales are sucking insects that insert their tiny, strawlike mouthparts into bark, fruit, or leaves, mostly on trees and shrubs and other perennial plants. Some scales change greatly in appearance as they grow, and some species have males and females that differ in shape, size, and color. The goal of insecticide-based efforts should be to prevent new regrowth from becoming infested by crawlers. Dispose of the pruned stems immediately. Honeydew also attracts other insects including bees, wasps, hornets and ants (Hymenoptera). For example, sago palms can be infested by the similar-looking cycad scale and oleander scale. Consider rotating work among several tools and using a freshly disinfected tool while the most recently used tools are being soaked in disinfectant. One of the primary ways gardeners realize they have an issue with scale is by the appearance of sooty mold on the plant. Synthetic chemical pesticides should be the very last resort in the war against scale. Armored scales, oak pit scales, and sycamore scale do not excrete honeydew. If plants perform poorly or are repeatedly damaged by pests, the best course of action may be to replace the plant with a pest-resistant species or cultivar that is better adapted to the site conditions. The use of brand names and any mention or listing of commercial products or services in this publication does not imply endorsement by NC State University or N.C. A&T State University nor discrimination against similar products or services not mentioned. Female nymphs are reddish-brown and about 1 2 mm long, and males nymphs are white and about 1 2 mm long. Honeydew also attracts ants that protect the Scale Insects from being attacked by predators and parasites, in return for a feed of the honeydew. Some female Scale Insect species lay eggs, while others give birth to live crawlers. Potential Distributions of the Invasive Barnacle Scale Ceroplastes If you see clusters of tiny shell-like bumps on the stems or leaves of a plant, there is a good chance you are looking at a scale. Purdue University Extension, Scale Insects. Each plate has a small, darker, spot usually surrounding a tiny button of wax. Since there are no natural predators indoors, insects like scale can continue to increase in numbers, unless caught early on. A member of the soft or unarmored scale family, mealybugs are a widespread garden pest and somewhat larger than most scale insects, making them easier to identify as an insect rather than disease. Fig trees, in particular, are easily stressed and shocked into losing their leaves. It's important to treat the entire plant, as scale can be present on stems, the undersides of leaves, and along the base of the plant. Nymphs are partially or nearly covered with a pattern of pure white conical wax plates that show up later as buttons on mature females. She has 30+ years of experience with year-round organic gardening; seed starting and saving; growing heirloom plants, perennials, and annuals; and sustainable and urban farming. The first nymph stage (instar) of the life cycle is known as a crawler that is a mobile six-legged creature about 0.5 mm long. Pest Notes: Cottony Cushion Scale. NC State Extension Plant Pathology Factsheets, NC State Horticultural Science Publications, North Carolina Agricultural Chemicals Manual. They love to hide. Horticultural oil is effective in spring or summer on deciduous plants when sprayed soon after most crawlers have emerged and most scales are in the young nymph stage. Leaves will fall when a tree is under stress. Gill, R. J. Other tiny creatures, including mites, may also be caught in the tape. Rust, M. K., and D. -H. Choe. Flipping the cover of a scale off may reveal parasitic larvae or a predator. The life cycle takes about eight weeks over summer and there are several overlapping generations per year. Texas A&M University - Department of Entomology 2475 TAMU College Station, TX 77843-2475 Check a portion of the scales to be certain they are alive and to evaluate the extent of parasitism as described above. 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. Insecticidal soaps can be used to kill scale at the larval stage, but they are not very effective once the insects are anchored and feeding under their protective shells. Calif. Agric. They are all sap-sucking insects. Monitor and record scale densities and use the density that caused damage (dieback or unacceptable honeydew) as your preliminary control action threshold. Any suggestions for treatment if this on a massive tree? In North Carolina, gardenia is the most common host. The small facial sponges, found in the cosmetic aisle, are abrasive, yet soft enough to use without scraping the plant stems. Underneath the wax cap, the body of the scale is red. Periodically check to ensure that plants have a good growing environment and are receiving appropriate cultural care. Eggs from beneath an adult female wax scale. Adult males are small winged insects that are rarely seen. OR, a plant expert will answer your individual plant and garden questions if you contact us by email or use the Quick Form below. Can I Spray My Ficus Tree With Soapy Water? Publ. First generation scales settle on leaves, but Scale Insects are sap-sucking insects with a lifecycle of incomplete metamorphosis and immature stages known as crawlers and nymphs. 3. Spraying your plants with horticultural oil is effective in late spring just before the leaves unfurl. Scale insects can overwinter as nymphs or Since there are no natural predators indoors, scale insects will spread even faster than they do outdoors. (PDF) 4(1) March 2014. A subreddit dedicated to gardening in Australia. Cottony Cushion Scale females lay about 1,000 red eggs into their egg sacs. Once a good feeding spot is found, the nymphs produce a waxy covering and remain there until adulthood. 4. Preserve the old sticky tapes by sandwiching them between a sheet of white paper and clear plastic. I have a very large and very old fig tree, and just discovered this scale type thing all over it. Thoroughly cover with spray the plant parts where scales occur, typically on twig terminals and the underside of leaves. WebAnthracnose (fungus Glomerella cingulata ): The fungus which causes anthracnose attacks both the fruit and the foliage. University of Maryland Extension, Scale Management Guidelines. Infection results in a small, sunken, discolored area. Grow a variety of flowering plants to help attract and support natural enemies. Neem oil and other treatments containing azadirachtin are regarded as organic pesticides and are not toxic to honey bees and most other beneficial insects. Wax scales, Ceroplastes spp. Soil-applied systemic insecticide products, such as those containing imidacloprid (e.g. As females age, they become a uniform brown colour. Gumtree Scales are a bit different in that females encase themselves in a globular sac, and they too produce honeydew. Properly applied, one application of an effective product may provide season-long control. This on a small, darker, spot usually surrounding a tiny button of wax D. -H. Choe about regulations.
