Mealybugs are sap-feeding insects that tap into the phloem via a piercing, straw-like mouthpart known as a stylet. Vine mealybug: Planococcus ficus The Situation: Vine mealybug was first found in California in the mid-1990s. 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. COMMENTS: In spring, ants in southern California and the Central Valley move the female mealybugs from the roots to plant parts above ground. preventing mealybugs moving into farms and fields that are currently mealybug-free; restricting movement of people and machinery in infested areas; regularly washing clothing and equipment that may transmit crawlers; keeping fields and non-crop areas free of alternative host plants. COMMENTS: To protect honey bees, apply only during late evening, night, or early morning when bees are not present. W. J.

PDF reader. Because several different species of mealybugs may infest grapevines, it is important to know which species of mealybug is present because management programs for the various mealybugs differ. Monitoring efforts can be aided by looking for ants and honeydew. Adult females are 3-5mm long, flattened oval-shaped white insects, which secrete a white, mealy wax that forms a row of hair-like filaments of fairly uniform length around the … Citrophilus mealybug (Pseudococcus calceolariae) is an exotic pest to Western Australia.It is a serious pest of of many horticultural industries that can downgrade fruit quality and affect fruit production. Scientific Name Grapevine leafroll-associated (CLRaV) closteroviruses. © Copyright 2020 CAB International. Argentine and gray ants tend vine mealybugs; therefore, observing ant activity can direct ones attention to where mealybugs are present on the vine. The scientific or taxonomic name would be Pseudococcus maritimus. Leaves and vines infested with grape mealybug were removed and sealed in 0.95-liter glass jars with paper towels for fumigation treatment. Preferred Common Name. Name Authority; Planococcus vitis (Nedzel'skii) Pseudococcus ficus (Signoret) Pseudococcus vitis (Nedzel'skii) Common names. MODE OF ACTION: Contact including smothering and barrier effects. By late spring and summer, vine mealybugs are found on all parts of the vine: hidden under bark and exposed on trunks, cordons, first- and second-year canes, leaves, clusters, and roots. The name mealybug is descriptive of the insect’s body, which is covered by a white sticky powder resembling cornmeal. Mating disruption is most effective when insecticides are used aggressively in the first year to reduce vine mealybug to low densities. Coastal regions only have two to three generations of vine mealybug per year, compared to five to seven in the lower San Joaquin Valley. COMMENTS: Efficacy of soil-applied neonicotinoids depends on soil texture. However, in the spring, the parasitoid does not emerge from its overwintering state until about bloom, providing minimal mealybug suppression during the early and midseason. 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. Several viruses in the ampelovirus group are associated with pineapple mealybug wilt disease, and are spread by these Dysmicoccus species. Similar species . Pseudococcus comstocki (Hemiptera: Pseudococcidae) Other common names . COMMENTS: Efficacy of soil-applied neonicotinoids depends on soil texture. Greater success has been achieved in northern California, where there are fewer generations of vine mealybug per year. Many species are considered pests by some humans as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector for several plant diseases. The most successful of these has been Anagyrus pseudococci. The presence of honeydew may also be an indication of vine mealybug presence. If vine mealybug is found in a vineyard, treatment is recommended. Monitor for vine mealybug by doing searches on the roots, trunk, cordon, leaves, and clusters depending on the time of year. Biological and cultural controls are organically acceptable management tools. COMMENTS: Efficacy of soil-applied neonicotinoids depends on soil texture. (Male vine mealybugs are smaller than adult thrips and are very difficult to see even with a hand lens.) Mealybug populations do no explode overnight, they usually have been present for a long time just as low population levels. Reduce cluster infestation by pruning vines to prevent clusters hanging directly on the cordon. Studies indicate it is effective in light soils. The Regents of the University of California. CABI is a registered EU trademark. 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. Scientific classification Kingdom: Animalia: Phylum: Arthropoda: Class: Insecta: Order: Hemiptera: Family: Pseudococcidae: Mealybug is the common name of insects in Pseudococcidae, a family of unarmored scale insects found in moist, warm climates.
