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. Horticultural oils have the advantage of helping to loosen sooty molds from the plant surface. Removing the scale by wiping it's hard body (oval, raised shape) is quite a task, but ultimately the most effective method. Wrap the ficus trunk with a thin band of tree wrap or masking tape and coat this wrap with a sticky material designed to Severe infestations may result in leaf discoloration, shoot or branch dieback and occasionally death of the host plant. 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. Pest Notes: Ants. Apply with a spray bottle or garden sprayer until all the leaves are dripping. Oil sprays suffocate small insects such as Scale Insects. If there is a reaction, discontinue use. A well-timed and thorough spray of horticultural (narrow-range) oil during the dormant season, or soon after scale crawlers are active in late winter to early summer, can provide good control of most species of scale. Change the tapes at weekly intervals. Infested plants sometimes turn almost black with sooty molds and plant growth is stunted. White Louse Scale females lay up to 150 eggs over a period of about three months. Introduction. 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. 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. 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. Female European fruit lecanium scale, one overturned to reveal eggs. Use a hand lens to examine the crawlers beneath mature female scales on bark or foliage to be certain of crawler appearance. Quick OR, a plant expert will answer your individual plant and garden questions if you contact us by email or use the Quick Form below. Leaves will fall when a tree is under stress. Quick search tells me it might be barnacle scale. 6. Beneficial insects such as soldier beetles, lady beetles , and parasitic wasps can be an important and effective control for scale insects. You Adult males are small winged insects that are rarely seen. A large rear plate has three buttons. 4. 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 unde 7470. Dreistadt, S. H. 2010. If ants are abundant, selectively control them. Scale insects can infest and damage many of the plants we grow in our landscapes and indoors.

Rice, Entomology, emeritus, Kearney Agricultural Center, Parlier. WebCover the bark and foliage as completely as possible. Scale insects are very adept at protecting themselves at most stages of their life cycle. Be sure to obtain current information about usage regulations and examine a current product label before applying any chemical. Soft Scale Insects, Cottony Cushion Scale and Gumtree Scale all produce honeydew, which is a liquid of concentrated plant sugars they excrete. For more information on monitoring honeydew, see the book Pests of Landscape Trees and Shrubs. What Kind of Bug Affects Ficus Trees Indoors? 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. For assistance with a specific problem, contact your local Cooperative Extension Center. Ant control, habitat manipulation, and pesticide management are the key natural enemy conservation strategies. 1998. Unlike the hard scales, Florida wax scale nymphs will often move from one location to another. Fig 3. (Homoptera: Coccidae). While you may not need to take all of these steps, you may need to employ a combination of them to defeat a scale bug infestation. Place enclosed pesticide baits (insecticide mixed with an attractant) near nests or on ant trails beneath plants. Except for crawlers and adult males, armored scales lack obvious appendages and spend their entire life feeding at the same spot. Systemic insecticides are absorbed by one plant part (e.g., trunks or roots) and moved (translocated) to leaves and other plant parts. 3386. To control scale on citrus and ornamental plants, including roses, spray withYates Scale Gun. Female nymphs are also circular but smaller. Most horticultural oils are some kind of petroleum-based mineral oil although there are some vegetable oils that also fight pests such as cottonseed oil and soybean oil. A toothpick I've found is great to remove them in those small areas. Avoid use on delicate plants such as African violets, ferns, seedlings, mosses or on flowers. Both males and females go through two immature stages before becoming adults. Can I Spray My Ficus Tree With Soapy Water? Nymphs are similar in shape and colour to adult females but are smaller. This is the first record of E. scitula predating on the invasive barnacle scale, C. cirripediformis.. Unlike other insects, they are immobile once they lock themselves into place to pierce the plant and begin feeding on sap. Julie Thompson-Adolf is a Master Gardener and author.

Division of Agriculture and Natural Resources 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. However, neonicotinoids vary in effectiveness for scale control. At this point, the nymphs have legs and are actively crawling to find new spots to attach and feed. Grafton-Cardwell, E. E. 2012. High scale densities may reduce the growth rate of the tree and can cause needles, shoots or entire branches to die. Publ. Soft scale insects attack plants by 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). We have found that Indian wax scale immatures are highly susceptible to Sevin insecticide sprays as well as pyrethroid sprays. Subscribe (RSS) 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. 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. Additionally, never apply the product when the plants are in direct sun or the temperature is above 90 degrees Fahrenheit. Male nymphs are oval and paler. To control most scales overwintering on deciduous woody plants, thoroughly spray the bark of terminal shoots with oil during winter. Place 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. They love to hide. Spraying your plants with horticultural oil is effective in late spring just before the leaves unfurl. Flint, M. L. 1998. 1. Pruning infected branches is often the easiest and surest solution if you catch the infestation while it is still light. Inspect the plant thoro Young third nymphs that have not completely secreted their waxy covering are also susceptible. Most soft scales have one generation each year and overwinter as second instar nymphs.

Neem oil may destroy an early rust infestation, but removing fallen debris will often prevent fig rust from taking root. 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. Females usually have egg sacs attached to them that are large, soft, cottony masses with a white fluted surface about 10 mm to 15 mm long. 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. Neem oil and other treatments containing azadirachtin are regarded as organic pesticides and are not toxic to honey bees and most other beneficial insects. It will make new leaves, but unless the source of stress is relieved, they will fall again. Cultural control. 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). Identification of E. scitula. Most species of armored scales have several generations a year and overwinter primarily as first instar nymphs and adult females. Publ. 5. Neem oil , or any pesticides containing azadirachtin , a key ingredient in neem oil, offer excellent protection against scale, and also will kil 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. Gill, R. J. The genus Ficus consists of more than 800 species, many of which are desirable foliage plants. Mature female Soft Brown Scales are flat, oval, about 4 mm in length, and a greenish-brown colour mottled with brown spots. Remove existing scale on houseplants by rubbing gently with a facial-quality sponge or cotton swab dipped in rubbing alcohol. Especially around air layers, stakes, in pruning cuts, etc anywhere they aren't visible is best. 4). Properly applied, one application of an effective product may provide season-long control. Figs may reduce stomach pain in a person with constipation. All contents copyright Double over the loose end of the tape several times to make it easier to remove. Hammon, A. Examine the tape with a hand lens to distinguish the crawlers (which are round or oblong and have very short appendages) from pollen and dust. This barnacle scale shows its plates of wax outlined by narrow depressions. Drees, B. M. and J. Adult female scales and immatures (nymphs) of most species are circular to oval, wingless, and lack a separate head or other easily recognizable body parts. WebIs this barnacle scale on my fig? Do not compost infected plant material; it is best to bag it up and throw it in the trash or burn it safely. After the insects have died, you can hose them off as well as any sooty mould they may have promoted. Other tiny creatures, including mites, may also be caught in the tape. A. Jackman. Most immature soft scales retain their barely visible legs and antennae after settling and are able to move, although slowly. Avoid creating dust because it interferes with natural enemies. Eggs hatch into tiny crawlers (mobile first instar nymphs), which are yellow to orangish in most species. Each instar can change greatly as it ages, so many scales appear to have more than two growth stages. Pink Wax Scales are about 4 mm in diameter, pink or red, and hard, with two lobes on each side and a depression in the middle. Honeydew drippings from plants can be efficiently monitored using water-sensitive paper, which is commonly used for monitoring insecticide droplets and calibrating sprayers. For oak pit scales, sycamore scale, and other harder to control species, spray during the plants delayed-dormant period, which is after the buds swell but before buds open. Although baits require users to be patient, they can be much more effective than sprays. After these scales have completely covered their bodies with wax (probably early summer), they are likely to be very difficult to control with sprays. Nat. 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. Scales. Orange crawlers hatch from the eggs and disperse over the tree. Planting a variety of fragrant, flowering ornamental plants and herbs near the ficus helps to attract beneficial scale predators to the area. Synthetic chemical pesticides should be the very last resort in the war against scale. Scale insects are usually divided into two groups: soft scale and hard or armored scale. Their surface is the actual body wall of the insect and cannot be removed; flipping the cover removes the insect body and cover together. Wrap the ficus trunk with a thin band of tree wrap or masking tape and coat this wrap with a sticky material designed to trap ants if you suspect that ants are feeding on honeydew produced by soft scales and protecting the scales from predators. Scale almost always appears in clusters. Wax and all, they are about inch long. Food Agric. Male forms have not been observed in this species. N.C. Insecticides differ in their effectiveness for certain scale types. In areas with hot summers, pruning to open up canopies can reduce populations of black scale, citricola scale, cottony cushion scale, and possibly other scales by increasing scale mortality from exposure to heat and parasites. Texas A&M University - Department of Entomology 2475 TAMU College Station, TX 77843-2475 Flint, M.L., and K. Windbiel-Rojas. The importance of infestations depends on the scale species, the plant species and cultivar, environmental factors, and natural enemies. Agric. With trunk injection and implantation it is difficult to repeatedly place insecticide at the proper depth. This is an outrageous example of sooty molds caused by barnacle scales. Neem oil, or any pesticides containing azadirachtin, a key ingredient in neem oil, offer excellent protection against scale, and also will kill the established insectsnot just the larva. Oakland: Univ. 4. Cir. Inspect the plant thoroughly, as well as any adjacent plants, to ensure you have removed all infested stems. Avoid methods that cause large wounds, such as implants placed in holes drilled in trunks. Wrap the trunk with a collar of fabric tree wrap, heavy paper, or masking tape to avoid injury to bark; wedge pliable wrap snugly into cracks and crevices; and coat the wrap with the sticky material. In Florida, this species has been recorded from many species of holly, elm, crape myrtles, oaks, loblolly pine, deodar cedar, citrus and other hardwoods and softwoods. 1. The small facial sponges, found in the cosmetic aisle, are abrasive, yet soft enough to use without scraping the plant stems. Control measures are most effective during what is called the scale insect's "crawler stage"the nymphs that appear soon after the eggs hatch. Scales, which generally appear on plant parts as immobile bumps, can cause leaf wilting, yellowing and premature drop. For more information see the California Department of Pesticide Regulation website. University of California Statewide Integrated Pest Management Program: Ficus, Fig, Indian Laurel, Laurel FigFicus spp. In Texas, the Florida wax scale has two fairly distinct generations per year (eggs hatching in late April through May and again in late July through August), although some eggs can hatch during other months. imidacloprid, a popular systemic insecticide (discussed below), controls soft scales and certain other scales but does not control armored scales or cottony cushion scale. After completing the larval stage and pupating, the emerging adult of internal parasites typically leaves a round exit hole in the scale it killed. Check back every ten days and thoroughly remove all the scale that you can find by tapping their bodies with alcohol on a cotton swab and then wiping away. Always sticky leaves and surfaces. B. and M. L. Williams. Costa Georgiadis, Press J to jump to the feed. "In gardens it's not just plants and insects and microbes that grow. 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. Scales are sucking insects that insert their tiny, strawlike mouthparts into bark, fruit, or leaves, mostly on trees and shrubs and other perennial plants. This publication printed on: March 01, 2023, Potential Distributions of the Invasive Barnacle Scale, The Scale Insects of California, Part 1, The Soft Scales (Homoptera: Coccoidea: Coccidae), The Soft Scale Insects of Florida, Homoptera: Coccoidea: Coccidae), Entomology Insect Biology and Management, NC Res. If a spring or summer foliar insecticide application is planned, unless another time is recommended for that species, spray after crawler production (abundance in traps) has peaked and definitely begun to decline, which is soon after most crawlers have settled. })(window,document,'script','dataLayer','GTM-NPR7B4'); Read our It is important to understand the link between scale insects, honeydew,antsandsooty mould. 11. Armored scale secretes a hard shell over its body for protection from predators. commitment to diversity. Some scale species lack males and the females reproduce without mating.

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. Immature fruit are dried up and may remain on the tree. Each plate has a small, darker, spot usually surrounding a tiny button of wax. 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. Because their use in landscapes and gardens can run or wash off into storm drains and contaminate municipal wastewater, these insecticides are being found in surface water and are adversely affecting nontarget, aquatic organisms.

Botany (Taxonomy, Nomenclature and Morphology). They then settle down to feed either on leaves, twigs or small branches. She holds a Bachelor of Arts in urban and regional studies. The Scale Insects you are likely to find on plants are mature females, and juvenile (nymphs) males and females. Barnacle scales, Ceroplastes cirripediformis, are reddish brown to brown but are completely covered with a thick layer (test) of pearly-gray wax. Systemic insecticides generally do not eliminate all scales located on branches or twigs, so the addition of foliar treatments may be necessary to eliminate the whole population. Calif. Agric. Marie Iannotti is a life-long gardener and a veteran Master Gardener with nearly three decades of experience. The authors are grateful for reviews of earlier versions of this manuscript by Carlos Bogran and Scott Ludwig. The oil coats the scale insects and clogs their breathing pores, suffocating them. 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. You can encourage these natural predators by providing them with food and shelter. Some systemic insecticides can cause spider mite outbreaks.
