Merit, Bayer Tree & Shrub Insect Control) should be applied prior to egg hatch to allow the active ingredient to be translocated from the soil, through the roots and into the leaf tissue. Hammon, A. 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. Botany (Taxonomy, Nomenclature and Morphology). A mix of 1 ounce of soap to a gallon of water is generally a good rule, but follow the package directions to be sure. Read our Any suggestions for treatment if this on a massive tree? This factsheet has not been peer reviewed. 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. Various species of ficus, members of the genus of the same name, are prized for their foliage and cultivated in the ground or in containers on patios or indoors. People grow too, and the best bit is that they don't realise it's happening. Cir. 3386. Scales in other families include important pests of cactus, elm, oak, sycamore, and various conifers. Mix the concentrate in a sprayer and apply thoroughly over the leaves or affected plant parts. Dispose of the pruned stems immediately.

Contact UC IPM, Agriculture and Natural Resources, University of California, 2021 Regents of the University of California Keep the plant well away from other plants until the problem is eradicated. Now, foliage of infested plants appears blackened with coatings of sooty mold, a fungus that grows on the sugary honeydew produced by these scale insects. Certain scale problems on large plants and hosts especially sensitive to scale damage may warrant the application of a systemic insecticide. WebPeriodically stir sticky material with a stick to prevent ants from crossing on collected debris. 2) are oval and reddish-orange in color, and fill the cavity underneath the bodies of dead or mature adult female scales. UC IPM Home > Homes, The Scale Insects of California Part 3: The Armored Scales. This is the time when they can be effectively killed with pesticides.

Drees, Professor, Extension Entomologist, Texas AgriLife Extension, James Reinert, Professor of Entomology, Faculty and Regents Fellow, Texas AgriLife Research, Michael Williams, Chair, Department of Entomology/Plant Pathology, Auburn University. Foliar sprays of broad-spectrum insecticides with residues that can persist for weeks are not recommended for scale control in landscapes and gardens. 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. I have a 35 year old indoor ficus benjamina tree, about 8 feet tall. Ant control, habitat manipulation, and pesticide management are the key natural enemy conservation strategies. The small facial sponges, found in the cosmetic aisle, are abrasive, yet soft enough to use without scraping the plant stems. After completing the larval stage and pupating, the emerging adult of internal parasites typically leaves a round exit hole in the scale it killed. Res. Although hollies have historically been a good choice as landscape plant species and are well adapted to the environmental conditions in Texas, the situation has changed over recent years. Soil-applied systemic insecticide products, such as those containing imidacloprid (e.g. You will need to be extremely diligent about controlling or removing scale when it infests indoor plants. Flint, M. L. 1998. Look at the tape through a hand lens, examining it for immature scales that are in their active crawler stage and appear as tiny yellow or orange specks. Do not apply oil or other insecticides when it is foggy, freezing (under 32F), hot (over 90F), when relative humidity is above 90%, or if rain is expected in the next 24 hours.

The covers often have a differently colored, slight protuberance (exuviae or nipple) and concentric rings may form as nymphs (immatures) grow and their cover enlarges. We answer questions in the order received. Accessibility That sticky stuff on the leaves is the secretion from the insect. Certain home-use products can easily be drenched into soil around the tree trunk using the mix-and-pour method. The shell also makes it difficult to use a pesticide because it has trouble reaching the insect inside. You will have to keep an eye out so as to remove all those hard scale where they appear, again, usually on the stems. Place a tag or flagging near each tape so you can readily find it. 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. First stage (instar) nymphs, called crawlers (Fig. Oakland: Univ. Soft Scales and Cottony Cushion Scales also produce vast amounts of honeydew. Scale Insects are sap-sucking insects with a lifecycle of incomplete metamorphosis and immature stages known as crawlers and nymphs. Scale Insects dont look like insects, because the insects body is mostly hidden under a hard or soft cover, which looks like a scale. The care is very similar for all ficus houseplants. 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. 2012. Soft scale is covered with a protective waxy substance and is somewhat easier to kill than hard/armored scale. Carefully follow label directions. Armored scales, family Diaspididae, have a flattened, platelike cover that is less than 1/8 inch in diameter. 2018. Spraying your plants with horticultural oil is effective in late spring just before the leaves unfurl. Quick search tells me it might be barnacle scale. Outdoors beneficials, like lady bugs, can help by devouring the scale pests. Publ. Rubbing alcohol can kill scale insects if the infestations are light. Especially around air layers, stakes, in pruning cuts, etc anywhere they aren't visible is best. Nat. Cultural control. Natural Enemies Handbook: The Illustrated Guide to Biological Pest Control. Nymphs are similar in shape and colour to adult females but are smaller. The twicestabbed lady beetle, Chilocorus orbus, is shiny black with two red spots on its back. However, timing is everything and there is a very short window of opportunity. You may effectively address minor scale infestation on small ficus trees by rubbing each scale with a cotton swab soaked with rubbing alcohol. For more information on monitoring honeydew, see the book Pests of Landscape Trees and Shrubs. This is the first record of E. scitula predating on the invasive barnacle scale, C. cirripediformis.. Wax Scale nymphs resemble smaller versions of adult females. Entomology Insect Notes, NC State Extension Publications. Do not spray oystershell or olive scales during the dormant season because susceptible stages of these species are not present during winter. Infested plants sometimes turn almost black with sooty molds and plant growth is stunted. commitment to diversity. Armored scale secretes a hard shell over its body for protection from predators. 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. 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. To know how and when to effectively make an application, learn more about the available insecticides and the biology of your pest species. Yellow patches on leaves around feeding scales. Leaf Blight Pellicularia kolerga ( leaf blight) is 5. Neem oil , or any pesticides containing azadirachtin , a key ingredient in neem oil, offer excellent protection against scale, and also will kil Crawlers go through several moults under scale covers, before becoming adults. Spray your plants at this point using a hose-end sprayer or garden sprayer filled with 2 to 5 ounces of oil per gallon of water. University of California Statewide Integrated Pest Management Program: Ficus, Fig, Indian Laurel, Laurel FigFicus spp. Certain plants may be sensitive to oil-based sprays, so do a test spray on a small inconspicuous area and observe over the next couple of days to see if there is a reaction. When populations are high, trees appear to be flocked with white specks (Fig. The Soft Scale Insects of Florida (Homoptera: Coccidea) in Arthropods of Florida and Neighboring Land Areas Vol. The crawlers moult to the second nymph stage and become sedentary like the adult females. 6. Beneficial insects such as soldier beetles, lady beetles , and parasitic wasps can be an important and effective control for scale insects. You However, their biology may not be that precisely synchronized, as nymphs have been photographed on leaves and stems well into early winter. Publ. Honeydew also attracts other insects including bees, wasps, hornets and ants (Hymenoptera). Figs may reduce stomach pain in a person with constipation. 11. "In gardens it's not just plants and insects and microbes that grow. They love to hide. Scale Insects on Shade Trees and Shrubs. While there can be some success in using systemic insecticides that include compounds known as neonicotinoids (acetamiprid, dinotefuran, imidacloprid, and thiamethoxam), these pesticides are now known to be a serious problem for honey bees and other pollinators. Publ. commitment to diversity. Before applying insecticide, make sure plants are receiving appropriate cultural care and take steps to conserve natural enemies. Mature female Soft Brown Scales are flat, oval, about 4 mm in length, and a greenish-brown colour mottled with brown spots. Pest Notes: Sycamore Scale. Insecticides differ in their effectiveness for certain scale types. PDF reader. Fig. The female wasp lays one or several eggs in or on each scale, where the tiny maggotlike wasp larvae feed. Trace back trail-making ants to locate colonies of the honeydew-producing insects. 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. Each instar can change greatly as it ages, so many scales appear to have more than two growth stages. Female nymphs are reddish-brown and about 1 2 mm long, and males nymphs are white and about 1 2 mm long. 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. Monitor and record scale densities and use the density that caused damage (dieback or unacceptable honeydew) as your preliminary control action threshold. Imidacloprid controls European elm scale and most soft scales but does not control cottony cushion scale and most armored scales. White Wax Scales are about 6 mm in diameter, white, soft and moist. On holly, Florida wax scales are easily spotted because most of them colonize the upper leaf surface. Adult males are rarely seen and are tiny, delicate, white to yellow insects with one pair of wings and a pair of long antennae.

Soft Brown Scale camellia, citrus, daphne, ferns, fig, oleander, orchids, palms, passionfruit and peach. FOR ALL OTHER USES or more information, read Legal Notices. After these scales have completely covered their bodies with wax (probably early summer), they are likely to be very difficult to control with sprays. 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. Oakland: Univ. 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. There are two to six generations per year, depending on the climate. 7470. Do not apply horticultural oil when it is foggy or rainy or when temperatures are above 90 degrees Fahrenheit or if these conditions could occur within 24 hours of application. You can encourage these natural predators by providing them with food and shelter. Res. Quick removal can prevent the scale from migrating to surrounding plants. 1e). Do not compost infected plant material; it is best to bag it up and throw it in the trash or burn it safely. For example, oil will remove the desirable bluish tinge from blue spruce foliage, although the plants health is not impaired.

Be sure to buy plain sponges without cleanser or lotion in them. Barnacle scales, Ceroplastes cirripediformis, are reddish brown to brown but are completely covered with a thick layer (test) of pearly-gray wax. Several applications will be necessary to catch all the larvae because these soaps don't last long in the elements, but these organic pesticides will not leave a dangerous environmental residue. Synthetic chemical pesticides should be the very last resort in the war against scale. Viewed from the top, they are rectangular, oval or lobed at the base. Hoping for a systemic treatment, there's tens of thousands of leaves on this tree! If the descending ants have swollen, almost translucent abdomens, they may be feeding on honeydew produced by scales or other insects. 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. This application will smother the scale before the insects have a chance to form their protective coating. Common scales and their tree and shrub hosts are listed in Tables 13. If ants are abundant, selectively control them. Especially at locations with hot weather, be sure plants are well irrigated before spraying foliage. 4. As you gain experience, refine this threshold over time for your local situation. Of course, these other landscape ornamental plants may have other limitations. Apart from biological control (seeNatural Enemies), the mainstay of Scale Insect control is the application of horticultural oils. After the insects have died, you can hose them off as well as any sooty mould they may have promoted. Since there are no natural predators indoors, insects like scale can continue to increase in numbers, unless caught early on. Publ. Alternative shrubs to hollies in eastern Texas include junipers (except Blue Point), Ligustrum, privet, boxwood, pittosporium, bottle brush, sea grapes, oleander, wax myrtle (regular and dwarf). Avoid creating dust because it interferes with natural enemies. Some systemic insecticides can cause spider mite outbreaks. Nymphs are partially or nearly covered with a pattern of pure white conical wax plates that show up later as buttons on mature females. Sometimes the immature parasites are visible through the scale surface. Systemic insecticides are absorbed by one plant part (e.g., trunks or roots) and moved (translocated) to leaves and other plant parts. UC Statewide IPM Program. This barnacle scale shows its plates of wax outlined by narrow depressions. For assistance, contact your local N.C. The tree is not generally very cold hardy and new growth in Spring can be damaged by temperatures of -1C (30.2F). Longer cutting with root nodes 3.

Inspect trunks for ants periodically during the growing season. Only apply insecticidal soaps to plants that are well hydrated or you can risk damaging them. 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. Entomol. Cottony cushion scale, European elm scale, soft scales, and certain other scales secrete sticky honeydew. Place Soft scales include black scale, brown soft scale, Kuno scale, lecanium scales, and tuliptree scale. Fig 2. 7409. Most scale insects are very small, usually ranging in size from 1/16 to 1/8 inch long. We are also grateful to Gary Plaia of Katy, Texas for monitoring scale crawler hatches and reporting success in treating infested hollies in southeast Texas. Except for crawlers and adult males, armored scales lack obvious appendages and spend their entire life feeding at the same spot. Remove existing scale on houseplants by rubbing gently with a facial-quality sponge or cotton swab dipped in rubbing alcohol. More than one application per growing season may be needed, especially if the targeted pest has more than one generation a year. The Spruce uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. These insecticides have low toxicity to people and pets and relatively little adverse impact on the populations of pollinators and natural enemies and the benefits they provide. 1993. White Louse Scale females lay up to 150 eggs over a period of about three months. What Kind of Bug Affects Ficus Trees Indoors? 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. Res. Band tree trunks with horticultural glue to prevent ants climbing up. Removing the scale by wiping it's hard body (oval, raised shape) is quite a task, but ultimately the most effective method. Treatment options include use of soil-applied systemic insecticides and/or foliar sprays with label directions for control of scale insects or soft scale on ornamental landscape plants (See Applying Systemic Soil and Foliar Spray Insecticides to Control Florida Wax Scale on Hollies). Marie Iannotti is a life-long gardener and a veteran Master Gardener with nearly three decades of experience. It's about 6m tall and 6m wide. But if this is not practical, then are several control methods that have proven effective against scale. 2012. See Pest Notes: Ants for more information. Staff-only pages The observed E. scitula larvae were bright pink to reddish in color with enlarged posterior body. Costa Georgiadis, Press J to jump to the feed. Other common scale victims are magnolia and fruit trees. 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. 4.

Eliminating the barnacle scales is the first step in reducing sooty molds on infested shrubs. 74160. 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. If you catch the problem early enough, pruning out the infested stems could alleviate the problems. imidacloprid, a popular systemic insecticide (discussed below), controls soft scales and certain other scales but does not control armored scales or cottony cushion scale. Adult and early star-like immature stages. But the treatment of scale is much different than the treatment for plant diseases, so it is important to know the difference if you want to treat and correct the problem. No. The Scale Insects of California Part 1: The Soft Scales. B. and M. L. Williams. Periodically stir sticky material with a stick to prevent ants from crossing on collected debris. Foliage sprays of systemics can be toxic to beneficial insects that contact spray or treated leaves. Rust, M. K., and D. -H. Choe. 2004. Fig trees can be successfully grown on many types of soil but will grow optimally in deep sandy-clay loams with a pH between 6 Place enclosed pesticide baits (insecticide mixed with an attractant) near nests or on ant trails beneath plants. See our Home page, or in the U.S., contact your local Cooperative Extension office for assistance. Soft, thin, strong growing tip - 2. Apply with a spray bottle or garden sprayer until all the leaves are dripping. The identity of E. scitula was confirmed based on its morphological characters and molecular analysis (Fig. Trunk application of an effective systemic insecticide can provide relatively rapid control. Make sure that the ficus is well-watered, as oil can injure plants that are under drought stress. Periodically check to ensure that plants have a good growing environment and are receiving appropriate cultural care. The importance of infestations depends on the scale species, the plant species and cultivar, environmental factors, and natural enemies. Cottony Cushion Scale females lay about 1,000 red eggs into their egg sacs. OR, a plant expert will answer your individual plant and garden questions if you contact us by email or use the Quick Form below. WebThey love to hide. The adult female of the Florida wax scale grows to about 3 mm (1/8-inch). This location makes the scales vulnerable to heavy rain and other environmental factors that reduce their ability to survive and are more easily reached with foliar insecticide sprays. Oil sprays suffocate small insects such as Scale Insects. We have found that Indian wax scale immatures are highly susceptible to Sevin insecticide sprays as well as pyrethroid sprays. However, some of the scales colonize the underside of leaves, on twigs and branches, where they are more protected. Many other species of wax scales occur in the state including the larger barnacle scale, C. cirripediformis Comstock, that grows to almost 1/4-inch in diameter (Drees and Jackman 1998). Quick Scales in this genus typically have one generation per year. To deny ants access to plant canopies, prune branches or weeds that provide a bridge between buildings or the ground and apply a sticky material (Tanglefoot) to trunks. A contact systemic insecticide such as products containing acephate (Orthene Tree, Turf and Ornamental Spray) can provide a longer period of control. Late spring and summer are also the times to spray avocado, citrus, and many other broadleaf evergreens. Pest Notes: Black Scale. Fla. Dept. j=d.createElement(s),dl=l!='dataLayer'? A hose-end sprayer is the preferred method of application for horticultural oils as it will make the oil last longer and cover a greater distance. Revised from a previous edition by J. G.
