Life History- The citrus mealybug has been recognized as a pest of citrus and ornamental plants in Europe since 1813 (where it is called the greenhouse mealybug) and in the United States since 1879. Jadhav RG, Madane NP, Kathamale, DK. Mealybugs appear frequently in ornamental and vegetable crops. The adultfemale isanoval, soft-bodied, immobile insect that is covered with a white, waxy sub stance. Males differ greatly; they have three instars and a pre-pupal stage. Meyers LE. Several overlapping generations occur in a year, but only one cycle (Spring-Summer) is of major concern to citrus growers in Florida, with peak infestations occurring in June or July. Some insects are susceptible to infections by the entomopathogenic fungus, Entomophthora fumosa (Speare 1922). A powerful force pump and penetrating insecticide, can be used to control mature insect populations. Large quantities of honeydew are produced by mealybug, which can turn black with the growth of sooty mould fungus. Mealybugs are primarily managed by conserving their natural enemies and reducing ant populations. After about 10 days, the egg sac hatches and the babies quickly spread out over the plant looking for feeding sites. Unlike other mealybugs, spherical mealybugs cluster in colonies on leaves and shoots. Appearance: Mealybugs are pink, soft-bodied insects that range in size from 1/20 to 1/5 of an inch. The longtailed mealybug gives birth to live young. University of Florida Agricultural Experiment Station Bulletin 591: 30-33. Crawlers are pink, less than 1mm long. The cultivation of citrus fruits. citrus mealybug comes in all parts of the plant. Mealybugs of California. The young are free of wax, but appear similar to the adult female. Griffiths JT, Thompson WL. Adults: Adult size ranges in length from 3 mm (females) to 4.5 mm (males). In California, banding the trees with sticky tree-tangle foot or baiting for ants is recommended to protect citrus plants from argentine ants that interfere with the activity of natural enemies (Davidson and Pearis 1956). Naturally occuring predators include lady beetles, lacewings and hoverfly larvae (Syrphids). The Macmillan Company, New York, USA. Life Cycle Of Mealybugs. In addition to actively crawling between trees, the insects may be transported by wind, on bird’s feet, or by machinery and labor crews (Kerns et al. Found on citrus throughout Western Australia. In north Queensland at least six generations are produced a year. passionvine mealybug, Planococcus minor Field specimens of citrus mealybug cannot be distinguished from passionvine mealybug. LIFE CYCLE. In addition, insecticidal soaps can be very effective when combined with natural predators of the mealybug. (1996) reported soybean as a host of citrus mealybug in India. Common predators include brown lacewing, Sympherobius barberi (Banks) and green lacewing, Chrysopa lateralis Guérin, trash bugs, syrphid fly larvae, and scale-eating caterpillars, Laetitia coccidivora (Watson 1918). 1957. Because female citrus mealybugs have no wings, they must be transported to the proximity of the next host plant. The common mealybug and its control in California. (croton), Cucumis melo (muskmelon),Cucurbita sp., Cyclamen sp. Treatment is rarely required and horticultural oil sprays are effective on young stages only. Life Cycle:The citrus mealybug has been recognized as a pest of citrus and ornamental plants in Europe since 1813 (where it is called the greenhouse mealybug) and in the United States since 1879. Muma MH. 15 Table 3. Photograph by Lyle J. Buss, University of Florida. Jadhav et al. United States Department of Agriculture and Farmer’s Bulletin 862: 16. After depositing the egg mass or live young over a period of 5–10 days, the female mealybug dies. 1917. The nymphs take six to 10 weeks to reach maturity. Mealybugs are primarily managed by conserving their natural enemies and reducing ant populations. Two economic greenhouse mealybugs of Mississippi. The long-tailed mealybug is slightly different in that females give birth to living young. All mealybug species have a similar life cycle. (fig trees or fig), Fragaria sp. Department of Primary Industries and Regional Development's Agriculture and Food division is committed to growing and protecting WA's agriculture and food sector. Male mealybugs live for two to four days after pupation. 1996. Citrus mealybug is the second most important vector of several strains of Cacao swollen shoot virus; symptoms include leaf chlorosis, ... (ZR-512) prolonged the duration of the total life cycle and reduced female fecundity (Gaaboub et al., 1979), but female emergence was much less affected. Photograph by Lyle J. Buss, University of Florida. Lebbeck Mealybug (Nipaecoccus viridis) Lebbeck Mealybug, Nipaecoccus viridis, is an exotic mealybug previously documented on dodder and tallow wood in Palm Beach County and intercepted at ports of entry.In June 2019, it was documented feeding on and damaging citrus in Highlands County, Florida. Females lay up to 500 eggs in a cottony egg sac attached to plants, fruit, bark or twigs. Side filaments are also long compared to the other two species. Life Cycle: Mealybugs lay up to 600 small, yellow eggs in a protective cottony mass. mealybug life cycle by | Oct 31, 2020 | Uncategorized | 0 comments In Florida, we mainly see the long-tailed, citrus, madeira, solanum, striped, solenopsis, papaya, Granara de Willink, Jack Beardsley and pink hibiscus mealybugs, according to the University of Florida. Mealybug bodies are distinctly segmented and usually covered with wax. The complete lifecycle takes about six weeks during the warmer summer months. Photo: Jeffrey W. Lotz, Florida Department of Agriculture and Consumer Services, Bugwood.org Life Cycle. They suck on the plant growth and cause deformation, stunted growth, leaf discoloration, leaf fall. Hosts: Citrus, landscape shrubs, indoor ornamentals. In addition to citrus, it has been found on a wide range of hosts including capsicum, fig, hibiscus, grape, mango, squash and tomato. Following the introduction of predatory beetles such as. A female can lay from 300 to 600 eggs in her lifetime, which are deposited in groups of five to 20. Citrus mealybug, upper; Cryptolaemus larvae, lower. First instar female and male nymphs are called crawlers. In the laboratory mature citrus mealybugs average 4 mm in length, and mature larvae of Cryptolaemus average 7 mm in length (exclusive of wax-covered setae). Mealybugs are in the insect family Pseudococcidae, part of the superfamily Coccoidea, which also includes armored scales, soft scales, and cottony cushion scale. For longtailed mealy bugs, the life cycle is only the crawler stage and adult, as female longtailed mealy bugs give birth to live young. Natural control of the citrus mealybug in Florida. Summer rains cause mortality by washing the mealybugs from plants. Long-tailed mealybugs don’t lay eggs, but bear live young in a manner similar to aphids. University of California Press, Berkeley, USA. Figure 4. Most other aspects of the life cycle depend on temperature, as well, including egg mortality, nymph mortality, rate of development, sex ratio, fecundity, and the length of the egg-laying period. Page last updated: Thursday, 23 July 2020 - 8:23am, LongtailedMealybugs&Crawlers DSC_0035.JPG, Longtailed mealybug (Pseudococcus longispinus), Pink hibiscus mealybug (Maconellicoccus hirsutus), Biosecurity and Agriculture Management Act, Western Australia's agriculture and food sector, Casual, short-term employment and work experience. 2001). During the summer all life stages are found on leaves and fruit, but when the weather becomes colder, the mealybugs move to more sheltered places such as under bark where they continue to reproduce. Life cycle and appearance of Citrus mealybug Adult females of Planococcus citri are 2.5 - 4 mm long and 2 - 3 mm in breadth. Since the mealybug secretes a waxy substance that it uses to protect itself, its eggs, and the young nymphs, it is often difficult to find an effective chemical control that will penetrate the substance. Chemical control: Chemical control of citrus mealybugs is often an inefficient management strategy due to their habit of hiding in crevices between foliage and fruit. 2008. In Queensland there are at least six generations per year, 4-5 in New South Wales and 3-4 in Victoria and South Australia. 2008). (banana), Narcissus sp. Cultural measures: Historically in California, fumigation of picking sacks and boxes was recommended to prevent the spread of citrus mealybug (Woglum and Neuls 1917). John Wiley and Sons Inc., New York, USA. Seldom-observed, the adult male is a very weak flier and does not have a mouth to feed, dying within a few days of emerging. It has been recognized as a difficult-to-control pest in Europe since 1813 (where it is called the greenhouse mealybug) and in the United States since 1879 (Anonymous 2007). Insecticides are also registered for mealybug control in citrus. IDENTIFICATION AND LIFE CYCLE. Pre-and post-bloom spray applications are recommended for management of mealybugs. Female nymphs have four instars. Feeding under and adjacent to the button of oranges results in fruit drop, reducing crop yields. The long-tailed mealybug is slightly different in that females give birth to living young. There is a dorsal line (barely visible) running the length of the body. Longtailed mealybugs do not produce an ovisac. 2003), coffee trees , cassava , ferns , cacti , gardenias , papaya, mulberry , sunflower and orchids . The longtailed generation time is longer than the citrus mealybug. In grapefruit groves, mealybugs persist in high numbers throughout the summer and into the fall. In Western Australia, mealybugs were highly damaging to citrus in the early 1900s. University of Florida Agricultural Experiment Station Bulletin 148: 214-216. Figure 3. 2001). Tail filaments are longer than, or as long as the body. Young mealybugs often creep up toward growing tips, earlier stages remain lower in the crop, in leaf axils or on the underside of leaves. Further research would be required to determine their ability to perform under field conditions. It is not commercially available. Citrus mealybug eggs appear as white cottony masses scattered about on the fruit, foliage, twigs, and bark of the tree. Female mealybugs are wingless and, therefore, must be transported to subsequent host plants, although they are able to crawl for short distances. 1922. The females are wingless, white to light brown in color, with brown legs and antennae (Figure 3). Mealybug species on citrus, its damage, seasonal incidence, natural enemies, varietal tolerance/susceptibility and management methods like cultural, … Citrus mealybug can be distinguished from other aboveground feeding mealybug spe cies by the possession of 18 pairs of short wax filaments on the body edge and one pair on the back. Because female citrus mealybugs have no wings, they must be transported to … Insect Environment 2: 90. 1932. Longtailed mealybug has pale yellow body fluid while spherical mealybug has purplish body fluid. Grapefruit is preferred over other citrus varieties (Griffiths and Thompson 1957). Biological control: Several natural enemies have been identified that are effective at controlling citrus mealybug. Life cycle duration (egg to egg-laying adult) can take up to six weeks in summer and twice as long in winter. The citrus mealybug (Planococcus citri) is the most common greenhouse species and is the most damaging. Confirmation requires slide-mounting and/or molecular testing of the adult female. Adult female is greyish-pink, 3 mm long and oval in shape. 1954. Depending on the season, egg hatch may occur after six to 10 days or several weeks. Nymphs can also be found on fruit. The body of the female is usually almost hidden by the large white domed egg sac. The species is readily propagated in large numbers under insec- tary conditions. Mealybug species; Mealybug control; Soft scales A shortened version of the URL, helpful when communicating the URL over email or verbally. Ahmed NH, Abd-Rabou SM. 525 pp. In Western Australia, this species has only been found in Kununurra, and in Australia is recorded as a problem only in north Queensland. Insects and mites found on Florida citrus. Males have an additional pupal stage from which they emerge as delicate winged insects with long tail filaments. For longtailed mealy bugs, the life cycle is only the crawler stage and adult, as female longtailed mealy bugs give birth to live young. These include Pseudococcus calceolariae (Glasshouse mealybug), P. longispinus (Long tailed mealybug) and Planococcus citri (citrus mealybug) and Rhizoecus species (root mealybugs). Wax and honeydew secreted by crawlers are visible indicators of infestations. Photo Charles Olsen, USDA. Woglum RS, Neuls JD. Photograph by Lyle J. Buss, University of Florida. Chemicals have been recommended for their control. High-pressure water sprays are moderately effective at achieving control. Mealybugs. Mealybug Life Cycle. There are three to four generations depending upon locality and seasonal factors. Treatment is rarely required and horticultural oil sprays are effective on young stages only. The glossy, light yellow eggs are oval and approximately 0.3 mm long. The Long-tailed mealybug breeds all year. An efficient predator of all three mealybug species is the mealybug ladybird. Mealybug species attack a wide variety of ornamental plants and fruiting plants such as citrus trees. (primrose or Persian violet), Cyperus sp. of feeding. The body just visible under the wax is a pinkish-red colour and when crushed, the body fluids are pink. Immature males and all stages of the female are similar in appearance. 12. Mealybugs remain motile throughout their life cycle, with the exception of the male pupa (Anonymous 2007, Griffiths and Thompson 1957, Polat et al. Davidson RH, Pearis LM. Mealybugs are less sensitive to petroleum spray oils than other citrus pests. The mealybug destroyer, Cryptolaemus montrouzieri, is a small (1/5") black lady beetle with a tan front end and a voracious appetite for mealybugs and some soft scales.This beetle was imported into the United States in 1891 from Australia by one of the early biological control pioneers, Albert Koebele, to control citrus mealybug in California. The body of adult females is coated with white wax and bears a characteristic faint gray stripe along their dorsal side. Yellowish eggs are laid in an egg sac resembling a white cottony mass behind the female. Immatures: Nymphs emerge from the ovisacs and typically settle along midribs and veins on the underside of leaves, young twigs, and fruit buttons. Repeated application of whale-oil soap, one pound in two to three gallons of water for young insects, has also been recommended (Hume 1954). McKenzie HL. Adult females live for an average of 87.6 days as adults and can start laying eggs seven days into their adult life. They are somewhat elongated and segmented and have waxy filaments extending from their hind end, giving the appearance of a tail. control of citrus mealybug and thrips. Two other lady beetles, Chilocorus stigma (Say) and Olla abdominalis var. Older individuals may have wax filaments around their body margins. In addition, ants get attracted by the honey-dew released by mealybugs and, therefore, frequently carry them from one tree to another (Watson 1918). Though economic damage is rare, damage to fruit can occur if populations are high. The life cycle is about 28 days at 80" F. Insectaries at Los Angeles, Oxnard and Santa Paula were supplied with large breeding stocks. Adults are black with a tan front end, 4mm long. Life History Citrus mealybug eggs are laid in a white cottony mass behind the female. Oranges develop hard lumps as a result of mealybugs feeding, resulting in discolored and poor quality fruit. It is only the males that can produce a cottony-appearing cocoon and pupate (Anonymous 2003, Kerns et al. Leptomastidea abnormis (Girault), Leptomastix dactylopii Howard, Chrysoplatycerus splendens Howard, and Anagyrus pseudococci (Girault) are common wasps parasitic of second and third instar nymphs (Anonymous 2007, Griffiths and Thompson 1957). Due to their habit of hiding in crevices, light infestations are easily overlooked. Scales hatch from an egg and typically develop through two nymphal instars (growth stages) before maturing into an adult. 2008). Wasp parasites of citrus mealybug in Australia include. Life Cycle: The citrus mealybug has been recognized as a pest of citrus and ornamental plants in Europe since 1813 (where it is called the greenhouse mealybug) and in the United States since 1879. Citrus Mealybug. Watson JR. 1918. Damage: Citrus mealybug feeding results in wilted, distorted, and yellowed chlorotic leaves, premature leaf drop, stunted growth, and occasional death of infested plants or plant parts. Spread: Dispersal of citrus mealybugs may occur through active or passive modes. The immatures can be blown by wind. It has been recognized as a difficult-to-control pest in Europe since 1813 (where it is called the greenhouse mealybug) and in the United States since 1879 (Anonymous 2007). Photo: Erfan Vafaie, Texas A&M AgriLife Extension. (coleus ), Codiaeum sp. Eggs: Eggs are deposited as white, cottony masses, called ovisacs, on the trunk and stems of citrus plants, giving the appearance of cotton spread on the plant (Figure 1). Other host plants include Amaryllis sp. 1954. Photograph by Lyle J. Buss, University of Florida. Australian mealybug lady beetles, Cryptolaemus montrouzieri Mulsant, little mealybug-eating lady beetles, Decadiomus bahamicus (Casey), and pictured ladybeetles, Scymnus flavifrons Melsheimer feed primarily on mealybugs. Longtailed mealybugs do not produce an ovisac. Short waxy filaments can be seen around the margins of their oval body with a slightly longer pair of filaments present at the rear end of their body. 2. Following emergence, males (Figure 4) live for one to two days during which they are incapable of feeding. (Jersey lily), Ananas comosus (pineapple), Annona squamosa (sugar-apple), Asparagus sp., Begonia sp., Bougainvillea sp., Cactus sp., Canna sp. Hedging citrus groves to reduce contact between trees and thorough cleaning of equipment and harvest materials were useful for reducing the spread of this insect in Arizona (Kerns et al. When squashed, the body fluid is pale yellow. Because mealybugs may be more abundant on some ornamental hosts, growth of these plants near citrus groves should be avoided. Some species of mealybug lay their eggs in the same waxy layer used for protection in quantities of 50–100; other species are born directly from the female. The citrus mealybug is a common pest of citrus primarily in greenhouses, and of several ornamental plants in Florida. Adult males are winged and thus capable of flying to new host plants for mating purpose (Anonymous 2007). Citrus Magazine 16: 16-17. (strawberries), Gardenia sp., Impatiens sp. The nymphs are yellow, oval-shaped with red eyes, and covered with white, waxy particles (Griffiths and Thompson 1957). Most common and widely established mealybug in Western Australia. When squashed, the body fluid is yellow. Insecticides are also registered for mealybug control in citrus. Mealybugs (family Pseudococcidae) are oval-shaped, segmented, soft-bodied insects covered with white, mealy wax. Breeding and development, however, is year-round in the greenhouse. Adult female 3-4mm long covered with a thin coating of white wax. (tulip) (Anonymous 2007, Martin and Mau 2007, McKenzie 1967, von Ellenrieder 2003). Most other aspects of the life cycle depend on temperature, as well, including egg mortality, nymph mortality, rate of development, sex ratio, fecundity, and the length of the egg-laying period. This mealybug is a vector of Swollen Shoot Disease of cocoa. Citrus mealybug lifecycle consists of an egg stage, three nymphal stages, and adult stage. Feeding weakens and stunts plants, causes leaf distortion and with spherical mealybug, shoots may twist if the infestation is heavy. The larvae resemble a mealybug, but are generally much larger. Females can lay up to 500 purplish eggs. Females can lay between 300-600 eggs and eggs take three to six days to hatch, depending on temperature. Acknowledgments I would like to say thank you to the following people for all the help they have offered me over the past 2 years: Thank you to Citrus Research International for providing the funding for this project. 2001), while male nymphs are more elongated. They are often found between touching fruit, under the calyx or in the 'navels' of oranges, producing honeydew on which sooty mould can grow. These anesthetized individuals appear unlifelike in the photo. Populations are usually low and no economic damage has been recorded by this species. (milkweed), Ficus sp. Additionally, the citrus mealybug (Planococcus citri) can also appear in cucumber, melon and aubergine. Life cycle. (For more information on chemical control, refer to Florida citrus pest management guide: Soft-bodied insects attacking foliage and fruit). Citrus mealybug populations are naturally regulated by parasitic fungi and predacious insects. There are four stages including the crawler stage. The longtailed generation time is longer than the citrus mealybug. Search for: Search Home; Pests and control agents. 2010. U.S. Department of Agriculture Bulletin 1117: 18. Based on laboratory studies on coffee leaves, male citrus mealybugs live (hatching to adult death) for approximately 27 days, and the females live for approximately 115 days. Scale insects and mealybugs on ornamental plants, Florida citrus pest management guide: Soft-bodied insects attacking foliage and fruit, California Department of Agriculture fact sheet: citrus mealybug (. (For more information on sooty mold, refer to Scale insects and mealybugs on ornamental plants.). The complete life cycle can take six weeks to two months depending on the species and the environmental conditions. In North America, it is present in both Mexico and the United States (Alabama, Arizona, Arkansas, California, Florida, Hawaii, Kansas, Louisiana, Maryland, Massachusetts, Missouri, New Mexico, Ohio, South Carolina, Tennessee, Texas, and Virginia) (CABI/EPPO 1999).
