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. Pour the soap into a spray bottle and spray the plant, including the undersides of the leaves and stems, until the soap solution begins to drip. 1991. A systematic revision of the wax scales, genus. Sooty mold on holly leaves. Several foliar sprays applied in 7 to 10 day intervals, or as directed on the product’s label, may be necessary to provide protection of new foliage through the period of egg hatch, particularly when using insecticide products with little or no residual activity such as insecticidal soap or horticultural oil.

A contact systemic insecticide such as products containing acephate (Orthene® Tree, Turf and Ornamental Spray) can provide a longer period of control. Soil-applied systemic insecticide products, such as those containing imidacloprid (e.g. Insects That Feed on Trees and Shrubs, 2nd ed.. Cornell University Press. Florida wax scale is thought to have originated from the northern Neotropical region and now occurs throughout the world, including, but not restricted to, the following countries: Africa: Algeria, Egypt, Kenya, Libya, Madagascar, Madeira, Mauritius, Morocco, Mozambique, Seychelles, Sierra Leone, Sudan, Tanzania, Uganda, Asia: Bonin Islands, Brunei, China, Cyprus, India, Iran, Israel, Japan (including the Ryukyu Islands), Korea, Lebanon, Malaysia, Pakistan, Sri Lanka, Syria, Taiwan, Turkey, and the more southern member countries of the former Union of Soviet Socialist Republics, Australasia and Pacific Islands: Australia, Caroline Islands, Mariana Islands, New Zealand, Central America and Caribbean: Costa Rica, Guatemala, Honduras, Panama, West Indies, Europe: France (including Corsica), Greece, Italy (including Sicily), Malta, Spain, South America: Brazil, Colombia, Ecuador, Guyana, Venezuela. Prune off and destroy any infested plant parts. Fla. Dept. Promote plant vigor and health by properly selecting preparing planting sites, and providing optimal watering and fertilization. Insecticidal soap, made from potassium salt of fatty acids, works by penetrating and destroying the outer shell or membrane of the insect causing it to dehydrate and die. This scale is considered a major pest of citrus (Citrus spp.) It may occur in the northern U.S., but it has not achieved pest status there because it cannot survive the winter (Hodges et al. 2) are oval and reddish-orange in color, and fill the cavity underneath the bodies of dead or mature adult female scales. Figure 4. 356 pp. Don’t have a shell, instead they secrete a cotton-like or waxy substance over their bodies for protection 5. Wax scales injure plants by removing large quantities of plant sap. 2000). Wax scales injure plants by removing large quantities of plant sap. Hammon, A. Scale insects and mealybugs on ornamental plants. Beginning in late April and again in mid-August, examine leaves on infested plants weekly or bi-weekly for newly settled nymphs that appear small, white and star-like as they begin to exude their wax coating. 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. Regulatory Hort. Prior to the Florida discoveries, the California Department of Food and Agriculture had intercepted specimens from Florida. Shaped like rounded bumps 4. Hiding under the "scale" covering (sometimes hard; sometimes fuzzy), these insects sit in one spot and suck plant juices—weakening or even killing the plant. Mass rearing of the Florida wax scale, Ceroplastes floridensis,for production of natural enemies. Coccidae, ‘Pink Wax Scale’. Florida wax scales have been reported infesting a wide range of host plants, including shrubs, trees and several herbaceous plant species. Florida Agricultural Experiment Station. Chemical control. Tea scale is a major camellia and holly pest in Florida. Figure 1. Systemic insecticides applied to the soil as a drench or sprayed onto foliage can effectively control scale infestations. 1998. 2000). It also makes them vulner- able to heavy rain and other environmental factors that reduce their ability to survive. Learn what to do if you see them. If hollies are selected for planting, inspect plants thoroughly to avoid purchasing already-infested plants. Unlike the hard scales, Florida wax scale nymphs will often move from one location to another. A few nymphs are visible at the left. 9. When planting, install them in a location that is suitable to their duration of light and soil type needs. Carefully follow label directions. Arthropods of Florida and neighboring land areas, Vol. Drees BM, Reinert JA,Williams ML. More and more landscape hedges of hollies (Ilex sp.) Viewed from the top, they are rectangular, oval or lobed at the base. Foliar treatments are best applied after the crawler stage hatches from eggs and begins to settle on new foliage. 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. 1974. Visually inspect plants regularly for early signs of infestation. Cottony cushion scale crawlers on sooty 2012. Photograph by Lyle J. Buss, University of Florida. Neem oil products work by suffocating the insect. The first generation occurs in April and May, the second is in July and August, and the third one occurs in October and November. 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). Argov Y, Podoler H, Bar-Shalom O and Rosen D. 1987. When infested plants are to be preserved, control should begin with pruning away and discarding heavily infested foliage. As a result of the scales consuming so much plant fluid, they excrete a considerable amount of a sugary, sticky honeydew, which then becomes colonized by a sooty mold fungus (Argov et al. Those scales that settle on the leaves often align themselves along the leaf midrib (Drees et al. Seven recently registered products (Altus, Mainspring, Pradia, Rycar, Sarisa, Ventigra and XXpire) looked promising on several species based on their efficacy relative to standards. Adult Florida wax scales, Ceroplastes floridensis Comstock. Photograph by Lyle J. Buss, University of Florida. Florida Wax Scale - Ceroplastes floridensis Comstock The adult female is covered with a thick layer of soft wax, about 2 to 4 mm in length and 1 to 3.5 mm in width. Ben-Dov, Y. However, some of the scales colonize the underside of leaves, on twigs and branches, where they are more protected. They adhere to and feed off of host plants. Florida wax scales: Control measures in Texas for hollies. United States: Florida. 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. 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. ISM555 provided good control of crapemyrtle bark scale and Madeira mealybug, while SP3014 provided good control of Madeira mealybug, in single trials. 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. (April 2009). Florida wax scales: A major pest of hollies and other landscape shrubs and trees. 536 pp. Consider junipers, ligustrum, privet, wax myrtle, or boxwood as alternative plants. Three generations of Florida wax scale occur in Florida (Johnson and Lyon 1991), but two generations per year are common throughout its global range. Scale insects can quickly destroy your plants, causing yellowing and dropped leaves. Honeydew also attracts other insects including bees, wasps, hornets and ants (Hymenoptera). B. and M. L. Williams.

The Florida wax scale, Ceroplastes floridensis Comstock, is one of the most commonly encountered soft scales throughout the southern United States, where it is a serious pest of citrus and several ornamental plants, like holly. Indian Wax Scale on the stem of cherry laurel. 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. We appreciate Chris Fox for providing suggestions of non-host ornamental plant alternatives to hollies. 2006a. 2000). Another New Scale in Florida Catharine Mannion University of Florida, IFAS Tropical Research and Education Center Greg Hodges Division of Plant Industry 2008 – Reported from Monroe County on croton • Continues to spread and Stimmel, J. F. 1998. Minimizing pest-prone plant species or varieties in a landscape is important when trying to reduce pesticide use. Florida wax scales are easily spotted on holly because most of them are found on top of the leaves. Plant death is also possible. 3 Avoid using regular house soap. 5% or more of green twigs infested with 1 or more scales. Since 2010, we have been monitoring Japanese maple scale populations to determine the life cycle of this scale insect in Maryland. Scale Insects and Mealybugs on Ornamental Plants 2 Figure 2. There are three instars (Drees et al. 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. Sticky honey dew, secreted by these scale insects is colonized by a fungus called, sooty mold, causing infested plant parts to turn black and unsightly. Native to Africa. 1974. Florida wax scales look like waxy, white domes about the size of a nail head and occur on a wide variety of plants. 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.
