Clothianidin has low water solubility, medium capacity to bind onto soil particles, and moderate to long persistence (weeks to months). Grapevine mealybug is a key economic pest of table and wine grapevines in South Africa as it vectors the grapevine leafroll virus. Label the trap with the block name and row number of its location and the dates it remains in the vineyard. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. Applications can be made as a tank mix with most pesticides that are not EC formulations or that do not contain oil. Mealybugs (Hemiptera: Pseudococcidae) are pests constraining the international trade of Brazilian table grapes. Scientific Name. Choose two trap sites for each 20-40 planted acres. During budbreak follow the monitoring guidelines in DELAYED-DORMANT AND BUDBREAK MONITORING (wine/raisin grapes or table grapes) to monitor these and other pests and record results on a monitoring form (example form—PDF). The name mealybug is descriptive of the insect’s body, which is covered by a white sticky powder resembling cornmeal. This species has provided up to 20% parasitism in some vineyards in the Coachella Valley and up to 90% parasitism of exposed mealybugs late in the season in the San Joaquin Valley. The reliability index shows the quality of evidence for the host association (0-10, 10=high quality). The female and nymphal mealybugs are wingless and are unable to fly so they must be carried by humans, equipment, wind, birds, or be present on vines at the time of planting. Mealybugs are very small soft, oval insects that are usually covered with a white or gray waxy fluff. If a cluster of mealybugs feeds along a fruit stem, fruit drop can occur. Biological and cultural controls are organically acceptable management tools. Grape mealybug culture was maintained on potted grape plants in a greenhouse under natural lighting at 10–30°C. Large populations of mealybugs appear as accumulations of white, cottony-looking wax on the plant.

Grape mealybug is present in Europe, Asia, New Zealand and North and South America High priority pest of: Dried fruit, Table grapes, Wine grapes Scientific name: Planococcus ficus Mating disruption is also approved for organic vineyards. Also, the mealybug itself will be found infesting bunches making them unfit for consumption. of imidacloprid (14 fl oz Admire Pro) /acre per year. Chlorpyrifos is also effective on ants, insect growth regulators can control scale pests, spirotetramat provides suppression of nematodes and phylloxera, and neonicotinoids are effective against sharpshooters and leafhoppers. Coccus vitis ; Dactylopius ficus ; Dactylopius vitis ; Planococcus citrioides ; Planococcus vitis ; Pseudococcus citrioides ; Pseudococcus ficus ; Pseudococcus vitis ; International Common Names. Buprofezin may harm the mealybug destroyer. When the soil is rewetted and plant roots are actively absorbing water, the insecticide is also absorbed by roots. Scouting Notes Basal leaves will exhibit symptoms in CP: contingency plan. 43. All or most life stages of the vine mealybug can be present year-round on a vine depending on the grape-growing region. (Male vine mealybugs are smaller than adult thrips and are very difficult to see even with a hand lens.) Grape It is currently localized in all grape-growing regions of California. Mealybug juveniles and adult females suck sap from all parts of the grapevine plant. When several references are cited, they may give conflicting information on the status. Take the sample to either your University of California Cooperative Extension (UCCE) farm advisor or county Agricultural Commissioner.

Most effective when applied during peak crawler emergence in the spring (typically late April–early May in the lower San Joaquin Valley and through June in the North Coast region). citrus mealybug, Planococcus citri The Comstock mealybug can be distinguished by a thicker wax cover than the more common citrus mealybug. When treating for vine mealybug, consider other pests. CP: contingency plan. In the spring, monitor the crown and trunk for adult females and the presence of crawlers moving up the vine. Treat infested vineyards immediately after harvest to minimize the movement of live mealybugs. It is currently localized in all grape-growing regions of California. Studies indicate this is the most effective neonicotinoid for heavy soils. A voracious feeder on mealybugs, C. montrouzieri is capable of eating 3,000-5,000 mealybugs in various life stages during its lifetime. Certain formulations emit high amounts of volatile organic compounds (VOCs); use. Synthesis of (1R 3R)-(+)-cis-acetoxy-methyl-3-isopropenyl-2,2-dimethyl cyclobutane- the sex pheromone of grape mealy bug (Planococcus citri) and its (1S, 3S)- (−)-cis enantiomer. However, the level of treatment varies greatly depending on the region, type of grape, and harvest date: Due to the complexity of these and other factors, such as biological control, decisions about the level of mealybug control need to be made on a vineyard-by-vineyard basis.

Mating disruption is most effective when applied over a large area (10 acres or greater). In vineyards with low mealybug pressure, a single insecticide application in the spring or at bloom is often sufficient for season-long mealybug control. Pseudococcus comstocki (Hemiptera: Pseudococcidae) Other common names . Growers can attempt to overcome this biological limitation of A. pseudococci by doing early-season releases of parasitoids that are purchased from commercial insectaries. Do not exceed 0.5 lb a.i. Use allowed under a Special Local Needs registration (SLN CA-080009). A mealy bug is about 1/10 of an inch long. this Primefact the scientific name Colomerus vitis is still applied to both bud and blister mites. Chlorpyrifos has been found in surface waters at levels that violate federal and state water quality standards. Fruit from a Flame Seedless vineyard, harvested on the first of July, is less susceptible to damage than fruit in a neighboring Crimson Seedless vineyard, which might be harvested in October. Citrus mealybug (Planococcus citri) is a major and frequent pest of many fruit and ornamentals throughout Australia. Since then it has spread throughout the state, becoming among the most significant vineyard pests. Grape Ivy, Cissus rhombifolia, has an appropriate common name because it is a member of the grape family, Vitaceae ... (worms), fungus gnats, mealybugs, mites, scales, and thrips. Leaves and vines infested with grape mealybug were removed and sealed in 0.95-liter glass jars with paper towels for fumigation treatment. Spray to obtain thorough coverage of all aboveground plant parts, especially the trunk and cordons where mealybugs are located. What is the scientific name or taxonomic classification of the Insect Species the Grape Mealybug? Compiled by Whitney Cranshaw, Colorado State University. Visually similar to the obscure mealybug (mentioned below), it is best identified by the color of its defensive excretions, which are a reddish-orange in hue. Ants must be controlled to keep them from The waxy filaments that protrude from the body of the vine mealybug are shorter than those on the Pseudococcus mealybugs, and the vine mealybug does not possess long tail filaments. In the North Coast, the first application is during late spring when crawlers are present or early summer. The exporter is to provide evidence attesting to the treatment (printout of data downloaded from temperature monitors) and to present to the authorised officer at the time of inspection. Oil applications are not used in table grapes, because they potentially affect the appearance of the fruit surface. CABI Data Mining, Undated. Greater success has been achieved in northern California, where there are fewer generations of vine mealybug per year. Adequate soil moisture is important at the time of application; follow label instructions carefully.

These traps can attract vine mealybug males from as far away as 1/4 mile. Please consider upgrading your browser to the latest version or installing a new browser. P. viburni, commonly known as obscure mealybug, is an unarmoured scale insect. If vine mealybug is found in a vineyard, treatment is recommended. Wallingford, UK: CABI, Golan K, Górska-Drabik E, 2006. If ants are not present, a vine with a large population of this pest can have so much honeydew that it resembles candle wax. A closely related species, the grey pineapple mealybug, Dysmicoccus neobrevipes also occurs. The grape mealybug (Homoptera: Pseudococcidae) has a flattened, oval pink body covered in a mealy white wax coating. Thus, when searching for vine mealybugs during summer, look for honeydew exudates on the clusters, trunk, and cordons. English: vine mealybug; Spanish: chinche harinosa de la vid; French: cochenille farineuse de la vigne; Local Common Names. Scientific Name: Pseudococcus longispinus (Targioni Tozzetti, 1867) Adult female Long-tailed mealybug, Pseudococcus longispinus (Hemiptera: Pseudococcidae) on a … Harvest dates vary widely in table grapes. Grape mealybugs that are parasitized by two tiny wasps, Acerophagus notativentris and Pseudophycus angelicus, have multiple emergence holes that are easily seen with a hand lens. Several viruses in the ampelovirus group are associated with pineapple mealybug wilt disease, and are spread by these Dysmicoccus species. MODE OF ACTION: Contact including smothering and barrier effects. Thank you for looking at my question. Zh Org Khim 27:555–558 Google Scholar. D. R. Haviland, UC IPM Program and UC Cooperative Extension, Kern County This parasitoid can be highly effective late in the season to reduce mealybug populations present after harvest before they return to the roots or lower trunk to overwinter. Description, life cycle, damage and control. Vine mealybug has a wide host range, feeding on several agricultural and weedy plant species. Period of Activity Most visible symptoms appear in mid to late summer. Vine mealybug: Planococcus ficus The Situation: Vine mealybug was first found in California in the mid-1990s. There are three to seven generations a year. Avoid drift and runoff into surface water. Argentine and gray ants tend vine mealybugs; therefore, observing ant activity can direct ones attention to where mealybugs are present on the vine. Phenacoccus dearnessi King Homoptera: Pseudococcidae Contents. Invasive Species List and Scorecards for California. Pseudococcus viburni (formerly Pseudococcus affinis (Maskell), and commonly known as the obscure mealybug and tuber mealybug) is a close relative of the grape mealybug (P. maritimus) and a pest of the vineyards of New Zealand, the Central Coast of California, and the tea gardens of northern Iran. The adult male is smaller than the female, has wings, and flies short distances to mate. Phenacoccus dearnessi (King) Common Names. The females and “crawlers,” or active young, cluster along the veins on the undersides of leaves. Scientific Name Grapevine leafroll-associated (CLRaV) closteroviruses. ORDER. FOR ALL OTHER USES or more information, read Legal Notices. Odermatt mealybug, Pseudococcus odermatti. A single-step multiplex PCR analysis was developed for three mealybug pests of grape, including Pseudococcus longispinus, and uses genetic differences to identify these species (Saccaggi et al. Vine mealybug: Planococcus ficus The Situation: Vine mealybug was first found in California in the mid-1990s. Table: Natural enemies of Long-tailed mealybug, Pseudococcus longispinus (Hemiptera: Pseudococcidae), from Plant-SyNZ database (27 December 2018). Studies indicate it is moderately effective in heavy soils. Use allowed under a 24(c) registration (SLN CA-080009). Mealybugs extract plant sap, reducing tree vigor, and excrete honeydew, which gets on plant surfaces and provides a surface upon which sooty mold grows. In table grapes and other hand-harvested vineyards, picking crews can be trained to be a valuable resource for reporting the presence of mealybugs in vineyards not known to be infested. F. G. Zalom, Entomology, UC Davis Eventually, sooty mold will grow on the honeydew and permanent parts of the vine will appear greenish black during the fall and winter. Other mealybugs found infesting grapes are only found on the aboveground portions of the vine. W. J. Bentley, UC IPM Program, Kearney Agricultural Research Center, Parlier The Northern Australia Quarantine Strategy (NAQS) has detected coffee mealybug on some Torres Strait Islands and near the tip of Cape York Peninsula on the mainland. An application rate of 5 g a.i./acre is sufficient to disrupt mating for 30 days. Golan K; Górska-Drabik E, 2006. For more information contact your local NSW DPI office.

It takes about 4 weeks after treatment to see the full effect. EPPO code: PLANFI. Like the grape, obscure, and longtailed mealybugs, vine mealybug can transmit grapevine leafroll-associated viruses. Table grapes have no allowance for mealybugs in the cluster, while wine grapes can tolerate low levels. One or more of the features that are needed to show you the maps functionality are not available in the web browser that you are using. When at low levels, they can be hard to find because of their ability to hide in plant cracks and crevasses. However, grapevines are a preferred host, and are the most adversely affected by this insect. They attach themselves to the plant and secrete a powdery wax layer (hence the name "mealy" bug) used for protection while they suck the plant juices. DP: diagnostic protocol. The vine mealybug has a pinkish body that is visible through the powdery wax, and it is slightly smaller than the Pseudococcus mealybugs. When using soil-applied neonicotinoids, growers should also be cognizant of soil type: imidacloprid (Admire Pro) and clothianidin (Belay) are more effective on sandy soils whereas thiamethoxam (Platinum) and dinotefuran (Venom) are more effective on heavier soil. Vine mealybug does not diapause during the winter, and it appears to be more sensitive to cold temperatures than grape mealybug. Studies indicate it is effective in light soils. The sex pheromone is specific to the vine mealybug, but the traps may also contain other male mealybugs depending on the site. Staff-only pages When fruit is present, especially after veraison, monitor clusters to ensure vine mealybug life stages or honeydew are not contaminating the fruit. Scientific Name Grapes (Fruit) Export Criteria; General ; Treatment ... Grapes intended for export to Vietnam may be treated concurrently with grape destined for other markets. Apply during January for grapes harvested in June in the Coachella Valley. Grape plants were grown in 18.9-liter containers with potting soil. Movement of equipment that pushes brush or any over-the-row equipment can be a major source of infestations in new locations; steam sanitize equipment before moving to uninfested portions of the vineyard. About Us; Contact Us; Navigation The scientific or taxonomic name would be Pseudococcus maritimus. If pheromone is being applied by itself, applications can be made to every other row. CAB Abstracts Data Mining., CABI, Undated. Mealybugs (Hemiptera: Pseudococcidae) are pests constraining the international trade of Brazilian table grapes. The parasites that attack Pseudococcus mealybugs do not attack the vine mealybug; therefore two potential candidates for biological control have been imported and released in California. Adequate soil moisture is important at the time of application; follow label instructions carefully. It potentially poses a multi-million dollar threat to numerous agricultural products in Florida, as well as other states, if not controlled. Family Name Pseudococcidae. May 15, 2019. Mealybugs also excrete honeydew which can lead to growth of sooty mould and to grape bunches becoming unmarketable. Thiamethoxam has high water solubility, medium capacity to bind onto soil particles, and short to medium persistence (days to weeks). What is the scientific name or taxonomic classification of the Insect Species the Grape Mealybug? Use chlorpyrifos for either ant control or mealybug control, but not for both pests on the same grape crop. Certain formulations emit high amounts of volatile organic compounds (VOCs); use. They may or may not be the host hibiscus mealybug, pink mealybug, grape mealybug other mealybugs (Hemiptera: Pseudococcidae) K. M. Daane, Kearney Agricultural Research Center, Parlier. Females deposit up to 600 eggs and die shortly thereafter. Mealybug, mite, and scale infestations are typically the result of bringing infested plant material into the greenhouse. In this study, our … During summer when vine mealybugs are in the canopy, they can be located well above the fruit zone and will lay eggs on the leaves, while Pseudococcus mealybugs do not. Do not apply in the North Coast; mealybugs are hidden under the bark at the graft union at this time of the year. It is somewhat segmented in appearance, but … This pest data sheet provides basic scientific information about Citrophilus mealybug and … Insecticide residues at the base of the vine will help control vine mealybugs in spring when they are being transported up the vine. common name: longtailed mealybug scientific name: Pseudococcus longispinus (Targioni Tozzetti) (Insecta: Hemiptera: ...
