[2] The introduction of this species has caused damage to papaya cultivation in South India, especially in the states of Karnataka, Kerala and Tamil Nadu. 1992. It potentially poses a multi-million dollar threat to numerous agricultural products in Florida, as well as other states, if not controlled. Adult females attract the males with sex pheromones. “It appears as cotton like masses on the plant and it … Mealybug infestations appear on plants as tiny, soft-bodied insects surrounded by a fuzzy, white mess around the stems and leaf nodes. 11 p. Noyes JS, Hayat M. 1994. To date, APHIS has found that the release of the four genera of parasitoid wasps has brought a 99.7% reduction in the density of mealybug populations at research sites in the Dominican Republic, and a 97% reduction at research sites in Puerto Rico, with parasitism levels between 35.5% and 58.3% (Kauffman et al. The papaya mealybug was discovered in Manatee and Palm Beach counties in Florida in 1998 and subsequently spread rapidly to several other Florida counties. Males have five instars, the fourth of which is produced in a cocoon and referred to as the pupa. The adult female has a yellowish segmented, flattened oval body about two millimetres long covered with mealy wax. Meyerdirk DE, Kauffman WC. Mealy bug is a type of insect which eats the juice from your plant and slowly kills your plants. Biological control. By January 2002, it had been collected 80 times on 18 different plant species in 30 cities throughout Alachua, Brevard, Broward, Collier, Dade, Hillsborough, Manatee, Martin, Monroe, Palm Beach, Pinellas, Polk, Sarasota, and Volusia counties. Female crawlers have four instars, with a generation taking approximately one month to complete, depending on the In 1999, the USDA Animal and Plant Health Inspection Service and Agricultural Research Service collected and reared four species of wasp from Mexico in a biological pest control experiment. In 1999, the USDA Animal and Plant Health Inspection Service (APHIS) and USDA Agricultural Research Service (ARS) initiated a classical biological control program for the papaya mealybug. Mealybugs of Central and South America. Papaya leaf deformation caused by the papaya mealybug, Paracoccus marginatus Williams and Granara de Willink. In addition to predators, several parasitoids may attack papaya mealybug. temperature. It infests nearly 60 host plants including Papaya, Tapioca, Mulberry, Bhendi, Brinjal, Tomato, Turmeric, Cotton, Jatropha, Kapak Agricultural Research, May 2000, 554 pp. In general, mealybugs have piercing-sucking mouthparts and feed by inserting their mouthparts into plant tissue and sucking out sap.

The papaya mealybug (Paracoccus marginatus) was first detected on Maui in 2004 and has since spread to O'ahu, the Big Island and Kaua'i. Figure 1. [7], The adult female deposits up to six hundred eggs into her ovisac over a period of one to two weeks. emerged as the dominant parasitoid species in both Puerto Rico and the Dominican Republic (Meyerdirk and Kauffman 2001). A. Heu, Mach T. Fukada, and Patrick Conant Introduction. The fifth instar male is a pupa in which the nymph undergoes metamorphosis into a winged adult. They introduced them into Puerto Rico and the Dominican Republic and achieved a reduction of the papaya mealybug populations in both countries of over 95%. [3] It has spread to certain Caribbean Islands, Hawaii and French Guiana,[4] and also to parts of Southeast Asia, including India, Indonesia and Thailand. 2001. The first releases of these four parasitoids were made in Florida in October 2000. Williams, D. J. and M. C. Granara de Willink. Due to this biological ability several authors have recommended members of the genus Spalgis in biological control programs against papaya mealybug and Spalgis epius is the most studied, particularly in India (Fig. 1992. Papaya mealybug infestations are typically observed as clusters of cotton-like masses on the above-ground portion of plants.

Figure 7. Parasitoids: Acerophagus papaya, Phygadium spp. Specimens were then shipped to Puerto Rico where they were cultured and mass-reared for experimental release in Puerto Rico and the Dominican Republic. Kauffman WC, Meyerdirk DE, Warkentin R. Biological control of papaya mealybug in the Caribbean Safeguarding the U.S. [9] All four have since been mass-reared and released in Florida.[2]. • Ovisac is three to four times the body length and develops ventrally beneath the body of the female. p. 16-17. Papaya Mealybug (Paracoccus marginatus) • Adult female is yellowish segmented, flattened oval, about two millimetres long covered with mealy wax. The eggs hatch ten days later and the crawlers, which resemble miniature versions of the adult female, disperse. It is assumed that most mealybug males locate females by a pheromone. The ovisac is developed ventrally on the adult female. Papaya mealybug, Paracoccus marginatus (Hemiptera: Pseudococcidae) is native to Mexico.

It was first described by Williams and Granara de Willink in 1992 from specimens collected on cassava. 2002. At the same time it injects a toxic substance into the plant which results in chlorosis, distortion, stunting, early leaf and fruit fall, the production of honeydew, sooty mould and possibly the death of the plant.[2]. It has also invaded Assam - a northeastern state of India As this happens the population of mealy bug is restrained to their minimum levels in favor of the crops , . In July 2008, the papaya mealy bug was reported in the Colombo and Gampaha districts of Sri Lanka (Galanihe et al., 2010). The adult female is yellow and is covered with a white waxy coating. 40 pp. Miller, D. R. and G. L. Miller. Adult males tend to be colored pink, especially during the pre-pupal and pupal stages, but appear yellow in the first and second instar. U.S. Department of Agriculture, Animal and Plant Health Inspection Service. Males can often be seen in flight early in the morning or late in the day when winds are generally calm. University of California Press, Berkeley. 5a–c). It is found on a number of different hosts, including economically important tropical fruit trees and various ornamental plants. [2], The papaya mealybug inserts its stylet into the epidermis of the leaf or the skin of fruit or stem and feeds on the plant sap. It potentially poses a multi-million dollar threat to numerous agricultural products in Florida, as well as other states, if not controlled. When the papaya mealybug invaded the Caribbean region, it became a pest there; since 1994 it has been recorded in the following 14 Caribbean countries: St. Martin, Guadeloupe, St. Barthelemy, Antigua, Bahamas, British Virgin Islands, Cuba, Dominican Republic, Haiti, Puerto Rico, Montserrat, Nevis, St. Kitts, and the U.S. Virgin The pest sucks the … papaya mealybug.

It doesn't restrict itself to papaya, and it's a "polyphagous sucking insect pest and has been recorded on more than sixty host plants in India." U.S. Department of Agriculture, Animal and Plant Health Inspection Service. Papaya mealybug infestations are typically observed as clusters of cotton-like masses on the above-ground portion of plants. The papaya mealybug is polyphagous and has been recorded on >55 host plants in more than 25 genera. Typically, twice the normal dose is applied when treating for mealybugs because mealybugs are protected by thick waxy, cottony sacs, and often are concealed inside damaged leaves and buds. It has since been found in Texas and California and it is likely to become more widely distributed on the Gulf Coast, and perhaps also in crops grown under glass further north in the United States. Adult females are approximately 2.2 mm long (1/16 inch) and 1.4 mm wide. Figure 4. 1999.

Papaya mealy bug is a polyphagous sucking insect pest and has been recorded on more than sixty host plants in India. The Papaya mealybug is small with males being 1 mm in size and the female 2 mm. Plants of economical importance are cassava, cocoyam, yam and avocado etc. Adult males may be distinguished from other related species by the presence of stout fleshy setae on the antennae and the absence of fleshy setae on the legs. Papaya mealy bug has created havoc in Tamil Nadu in the past two years. They’ll have to be burned to destroy the papaya mealy bug to help prevent it from spreading even further. Thus, chemical controls are only partially effective and require multiple applications. The papaya mealybug was described in 1992 from the Neotropical Region in Belize, Costa Rica, Guatemala, and Mexico (Williams and Granara de Willink 1992). Mealybugs are most active in warm, dry weather. Oriental Mealybug Parasitoids of the Anagyrini (Hymenoptera: Encyrtidae). Becker H. 2000. It has never gained status as a serious pest there, probably due to the presence of an endemic natural enemy complex. Furthermore, problems with insecticide resistance and non-target effects on natural enemies make chemical control a less desirable control option to combat the papaya mealybug. Papaya Mealybug, Paracoccus marginatus Williams and Granara de Willink (Insecta: Hemiptera: Pseudococcidae) 3 Miller and Miller (2002) give a complete description of all instars of both sexes of the papaya mealybug, as well as a complete description of characters used to distinguish the papaya mealybug from other closely related species.

Four genera of encyrtid endoparasitoid wasps specific to mealybugs were collected in Mexico by USDA and ARS researchers and Mexican cooperators as potential biological control agents: Acerophagus papayae (Noyes and Schauff), Anagyrus loecki (Noyes and Menezes), Anagyrus californicus Compere, and Pseudaphycus sp. All four species of parasitoids have been observed attacking second and third instars of P. marginatus. Natural enemies of the papaya mealybug include the generalists, e.g., ladybird beetles (including the so-called "mealybug destroyer", Cryptolaemus montrouzieri), lacewings, and hover flies. Economically important host plants of the papaya mealybug include papaya, hibiscus, avocado, citrus, cotton, tomato, eggplant, peppers, beans and peas, sweet potato, mango, cherry, and pomegranate. 1. Egg hatch occurs in about 10 days, and nymphs, or crawlers, begin to actively search for feeding sites. McKenzie H. 1967. PAPAYA MEALY BUG 1. Beside the papaya plant, its preferred host, the papaya mealy bug attacks many others plant species including crops, weeds and ornamentals. All four species were screened in USDA/ARS quarantine facilities in Newark, Delaware and environmental assessments were completed (USDA-APHIS 1999, 2000, 2002). It was recently noted in Réunion in the Indian Ocean. Papaya mealybug, Paracoccus marginatus (Hemiptera: Pseudococcidae), was first described by Williams and Granara de Willink in 1992 from specimens collected on cassava (Manihot utilissima Pohl) in Mexico. It is found on a number of different hosts, including economically important tropical fruit trees and various ornamental plants. Symtopms can be observed on ground parts of leaves, stem and fruits as clusters of cotton like masses; Natural enemeis of papaya mealybugs. [1] The antennae have eight segments in both sexes, a character which distinguishes this species from the hibiscus mealybug (Maconellicoccus hirsutus). Active ingredients in registered pesticide formulations include acephate, carbaryl, chlorpyrifos, diazinon, dimethoate, malathion, and white mineral oils. Redescription of. A number of chemical controls are available to control mealybugs, although none are currently registered specifically for control of papaya mealybug. Biological c… Mealybugs have from one to eight or nine generations a year depending on the weather conditions and species of mealybug. [5] In doing so, it injects a toxic substance into the leaves. /Plate 1.Symptoms and infestation of Papaya mealy bug in mulberry A. Nymphs and adults on terminal shoots Drawing by D. Miller and G. Miller, USDA. Natural enemies of the papaya mealybug include the mealybug destroyer (Cryptolaemus montrouzieri), other lady beetles, lacewings and hoverflies. Specimens of papaya mealybug turn bluish-black when placed in alcohol, as is characteristic of other members of this genus. Identification of Mealybugs Important in the Caribbean Region. Damages on papaya plant are huge and can lead to the death of the plant in case of explosive population. Small yellow-white insect that feeds on the sap of papaya and numerous other plants; Feeding causes leaf chlorosis, leaf distortions and can cause early fruit fall; While feeding, the mealy bugs produce honeydew which encourages sooty mould to … 2001. Status on the development of a biological control program for, Miller DR, Miller GL. The papaya mealybug feeds on the sap of plants by inserting its stylets into the epidermis of the leaf, as well as into the fruit and stem. It has already been identified on papaya plants in the Garfield Conservatory in Chicago, Illinois in late August of 2001. Heavy infestation of papaya mealybug on hibiscus.

The papaya mealybug, Paracoccus marginatusWilliams and Granara de Willink, is a small hemipteran that attacks several genera of host plants, including economically important tropical fruits and ornamentals. Eggs are greenish yellow and are laid in an egg sac that is three to four times the body length and Papaya Mealybug : success Story : Classical Biological control of Papaya mealybug – Success story: Since, July 2008, a sudden outbreak of papaya mealy bug, Paracoccus marginatus (Williams and Granara de Willink) was noticed in papaya, mulberry, tapioca, jatropa, vegetables, fruits, cotton, plantation crops, spices and flowers including several weeds in different parts of Tamil Nadu. Photograph by Dale Meyerdirk, National Biological Control Institute. Mealybugs only tend to be serious pests in the presence of ants because the ants protect them from predators and parasites. Outside of its natural habitat, Papaya mealybug is a polyphagous pest, with hosts recorded from 25 plant families. Control of the papaya mealybug. 2000. Females have no wings, and move by crawling short distances or by being blown in air currents. mealy bugs were chosen and tagged for study . The papaya mealybug, Paracoccus marginatus Williams and Granara de Willink, is a small hemipteran that attacks several genera of host plants, including economically important tropical fruits and ornamentals. CAB International, UK, 644 pp. The ovisac is well developed and visible underneath the posterior part of the body. The result is chlorosis, plant stunting, leaf deformation, early leaf and fruit drop, a heavy buildup of honeydew, and death. Figure 2. [6], The papaya mealybug feeds on over 55 plants in more than 25 genera. Specimens also have been intercepted in Texas and California, and it is expected that papaya mealybug could rapidly establish throughout Florida and through the Gulf states to California. It is possible that certain greenhouse crops could be at risk in areas as far north as Delaware, New Jersey and Maryland. Photograph by Dale Meyerdirk, National Biological Control Institute. Kauffman WC, Meyerdirk DE, Miller D, Schauff M, Hernandez HG, Villanueva Jimenez JA. “Papaya mealy bug originated from Central America and has been reported as pest of economic importance in 2009,” he explained. U.S. Department of Agriculture, Animal and Plant Health Inspection Service. A biological control program was implemented in December of 2001 with very successful results. 2001. Papaya mealybug has only been recorded feeding on areas of the host plant that are above ground, namely the leaves and fruit. [1] It was discovered in Bradenton, Florida, in the United States in 1998 feeding on hibiscus, and four years later it had been detected on eighteen different plant species in the state.
