The female fly can lay over 1500 eggs in its lifetime. Acrotoxa ludens Loew Common fruit fly is an important organism and widely used for genetic analysis in modern biology because it has only four pairs of chromosomes. Department of Entomology, University of California, Davis, CA 95616, USA. It has also spread into the cultivated citrus sections of the west coast of Mexico and northward toward Texas, Arizona and California, resulting in continual detection, survey, and eradication campaigns in these areas. The rate at which they mature is directly related to ambient environmental factors such as temperature and humidity. Characters of the larvae and pupae of certain fruit flies. Aluja M. 1994. Age and host effects on clutch size in the Mexican fruit fly, Anastrepha ludens . It is unclear if the species was native to Costa Rica or migrated there from the north. Using release-recapture technique, researchers observed flies moving back and forth between the two habitat areas. When fully grown, the larvae emerge through conspicuous exit holes, usually after the fruit has fallen to the ground, and pupate in the soil. This page was last edited on 21 December 2020, at 21:25. . Photo by Jeffrey Lotz, Division of Plant Industry. ), Rutaceae) (Plummer et al. (1993). However, adults are highly mobile and move easily from any nearby untreated trees back to treated trees after a few days. Anal lobes of larva. Figure 1. Subtropical Fruit Pests. Once the female makes her decision to lay eggs, she will bore into the fruit and deposit eggs. The Mexican fruit fly prefers living near citrus and other fruits, which act as hosts where the female can lay her eggs. Mexican fruit fly represents a particular threat to Florida because of its special affinity for grapefruit, of which Florida is one of the world's leading producers. Present: AZ, CA, FL, TX They have been observed landing on potential host fruit and walking around while headbutting the fruit. Department of Entomology, University of California, Davis, CA 95616, USA. Larval movement is dictated by the ripeness of the host fruit. [3] These qualities make the Mexican fruit fly a particularly aggressive invasive species, especially threatening agriculture because the larvae grow and feed on many different species of fruit. Over 600 species in 36 genera have been described in North America, the vast majority of which either feed on other insects or other non-human animals. Fruit fly infestations are difficult to eradicate, particularly if the source of the infestation is not found. . Larvae determine when to exit a fruit through physical and chemical signals such as the pH of the rotting fruit and the drop of the fruit from to the ground. Each year, the pest enters the Lower Rio Grande Valley’s 27,000 acres of commercial citrus crops from south of the border and attacks more than 40 different kinds of fruits. Ideal territories for males are under the leaves of trees that produce citrus fruit. 1990. [3], A. ludens have 12 chromosomes and most cells are diploid. [17], The main natural enemies of A. ludens are parasitoid wasps, specifically in the families Branconidae and Ichneumonidae. 1988. [3], The USDA utilizes integrated pest management tactics to control the threat of an invasion. The Mexican fruit fly larva is white with the typical fruit fly larval shape: cylindrical, elongated, anterior end usually somewhat recurved ventrally and with mouth hooks, flattened caudal end, eight ventral fusiform areas (one indistinct - between the thorax and abdomen), 11 segments to the body). [4], Most species in the Anastrepha genus including A. ludens have a distinctive yellow and brown coloration of the body and wings. The interspiracular processes (hairs) are mostly branched distally. These behaviors vary between different species of fruit flies. Federal Quarantine No. Males mating strategy involves claiming a territory and defending it from other males through sounds and physical actions. Mexican fruit fly represents a particular threat to Florida because of its special affinity for grapefruit, of which Florida is one of the world's leading producers. The adult female typically oviposits in citrus and other fruit at the time when the fruit begins to show color. Dose Queensland fruit fly Bacterocera tryoni 150 Sapote fruit fly Anastrepha serpentine 150 West Indian fruit fly Anastrepha oblique 150 Mexican fruit fly Anastrepha ludens 150 Caribbean fruit fly Anastrepha suspensa 150 Melon fly Bactrocera cucurbitae 210 Med. (1944); see also extensive references in Aluja (1994). Search for more papers by this author. The biology and identification of trypetid larvae (Diptera: Trypetidae). The females, wingless and about 5 mm (0.20 in) long, cluster on cactus pads. The ability of males of different ages to inhibit female remating is also determined, and the growth of male reproductive organs is measured as they age. 1980. The adult stage is susceptible to control, usually by a short-lived bait comprised of a contact insecticide mixed with protein and carbohydrate. It was previously believed that the species is native to Colombia because of misidentification of Anastrepha manizaliensis but it is now known that the species does not exist there. Accurate larval identification of A. ludens and other species of Anastrepha is difficult. [20] A 2014 genetic study of A. ludens concluded that "A. ludens populations are genetically diverse with moderate levels of differentiation." No. Phillips VT. 1946. The adult Mexican fruit fly is larger than a housefly, about 1.0 cm (0.38 inch) long. If a fly is trapped in an orchard, then all fruit from that orchard is quarantined for two weeks. Larval development requires approximately three to four weeks, depending largely upon temperature conditions during these periods of development. This is applied as fine droplets to host plant foliage where adults feed. [3], Female A. ludens exhibit mate choice and tend to prefer to mate with larger males. However, with the eradication of the Mexican fruit fly in the United States in 2012, this quarantine is no longer in effect (NAPPO 2012). The Fruitflies of the Genus. Adults may survive for many months, occasionally almost a full year, and males appear to be able to survive much longer than females, even as much as 16 months. 30°) and I3 is almost equidistant from L1 and I2. Movement of citrus fruit is restricted within the quarantined area. There are 12 to 14 anterior buccal carinae. [5] There has been at least one Mexfly quarantine in Texas on an annual basis for over 80 years. [8] A. ludens were rare in Costa Rica until the 1990s when they suddenly appeared on citrus plants. University of Florida, Gainesville. Most species in the Anastrepha genus including A. ludens have a distinctive yellow and brown coloration of the body and wings. Figure 9. Fruit Flies Follow Fermenting Fruit . The body color is a pale orange-yellow with two to three whitish stripes along the thorax. By Andrew Porterfield. 14-12-2020 Anastrepha ludens (Mexican Fruit Fly): APHIS Removes the Quarantine Area in Laredo, Webb County, and Zapata, Zapata County, Texas new; 14-12-2020 Anastrepha ludens (Mexican Fruit Fly): APHIS Removes the Quarantine Area in Harlingen, Cameron County, Texas new Figure 10. Cochineal insects are soft-bodied, flat, oval-shaped scale insects. Figure 4. While inside the fruit, the larvae continue to grow and develop through 3 larval instars. Continual detection, survey and eradication campaigns are being conducted in the cultivated citrus sections of northwestern Mexico adjacent to California, and occasionally in the southern part of California when new invasions are detected. Sterilization of fruit before shipment from quarantined areas is required. 45°) and as widely separated as I1 & I2; I1 & I2 less acutely angled (ca. The adult A. ludens is 7–11 mm long, or slightly larger than a common house fly. Figure 6. Larva: The larval descriptions were made from reared and verified specimens acquired from the U.S. National Museum of Natural History (USNM), Washington, and from other identified lots of larval specimens at the Florida State Collection of Arthropods (FSCA). Then she deposits a host-marking pheromone over her eggs. Physiological Entomology, 01 Mar 2017, 42(1): 26-35 DOI: 10.1111/phen.12160 AGR: IND605718309 . 1994. [3], During pupation, the larvae undergo complete metamorphosis to change into adult flies. However, cutting fruit after harvest or late season is a good method of estimating populations. Figure 5. US Department of Agriculture, APHIS Fact Sheet, Mexican Fruit Fly, Doc. Pruitt JH. The pharyngeal plate is longer than the dorsal wing plate and has a long pharyngeal support. Other hosts include cherimoya, custard apple, mamey, pomegranate, quince, rose apple and yellow chapote. [4] The first record of these flies spotted outside of their native habitat of Mexico and Central America was in a small Texas colony in 1903. Posterior spiracles (left group) of larva. Identification of Fruit Fly Larvae Frequently Intercepted at Ports of Entry of the United States. The gut bacteria may also play a role in digestion and detoxification of chemicals. 1953. Fruit fly populations can be a problem in restaurants, homes, supermarkets, food plants, warehouses and any other locations where food is processed, served or stored. 29-54. Anterior spiracles of larva. However, the main characteristics of each species appear to be constant and allow relatively easy identification. [16], A. ludens have been observed migrating about 135 km from their breeding site in Mexico to farms in southern Texas. The genus Anastrepha comprises about 200 species distributed throughout the Americas. An experiment showed that combining females and males together in cages during maturation reduced egg production. [3], The larval stage lasts for 3–4 weeks, depending on the temperature and other conditions. The last instars are usually 9–12 mm in length. Figure A-4 Sapote Fruit Fly (Anastrepha serpentina) A-10 Figure A-5 Guava Fruit Fly (Anastrepha striata) A-12 Figure A-6 White Striped Fruit Fly (Bactrocera albistrigata) A-15 Figure A-7 Carambola Fruit Fly (Bactrocera carambolae) A-17 Figure A-8 Guava Fruit Fly (Bactrocera correcta) A-22 Figure A-9 Melon Fruit Fly (Bactrocera cucurbitae) A-26 The posterior spiracles are elongated (ca. Wings are 5.9–7.7 mm long, with yellow brown bands; costal and S bands touching on vein R4+5 and usually again just anterior to vein R2=3, leaving a small hyaline spot in cell R3; V band complete, separated from S band, outer arm narrow. The ovipositor is 3.35–4.7 mm long. In grapefruit as well as many other fruits, one female Mexican fruit fly, Anastrepha ludens (Loew), can deposit large numbers of eggs: up to 40 eggs at a time, 100 or more a day, and about 2,000 over her life span. The eggs hatch 6–10 days later and then enter their second stage of development, the larval stage. . Males live even longer than females, up to 16 months. Fruit Flies of Florida (Diptera: Tephritidae). Like other Anastrepha species, A. ludens does not respond to any known sex attractant that can be usefully employed in a detection trapping system. The medial vein (M1) curves forward at the wing tip. Photo by Jeffrey Lotz, Division of Plant Industry. Me… The Sterile Insect Technique is used in maintaining a fly-free zone in Mexico, Texas and California. There is a period of sexual maturation during which they eat lots of protein which allows for gonadal development. The wings are clear except for several yellow and brown stripes. In addition they found high levels of inbreeding in the species. Clark RA, Steck GJ, Weems Jr HW. Fly, (order Diptera), any of a large number of insects characterized by the use of only one pair of wings for flight and the reduction of the second pair of wings to knobs (called halteres) used for balance. It is thought to be native to the Sierra Madre of northeastern Mexico because it breeds there in a wild citrus, yellow chapote (Sargentia greggi (S. The cephalo-pharyngeal skeleton is not usually examined in routine identifications because the larval specimen must be dissected before this character can be examined. Mexican fruit fly represents a particular threat to Florida because of its special affinity for grapefruit, of which Florida is one of the world's leading producers. [3], Male A. ludens exhibit lek mating and thus do not provide any care for offspring outside of fertilizing the egg. The Mexican fruit fly, Anastrepha ludens(Loew), is a very serious pest of various fruits, particularly citrus and mango, in Mexico and Central America. Previously, a single fly was captured in a McPhail trap in Sarasota in 1972 (Clark et al. These insects are very small—about two to four millimeters long—and vary in color from yellow to brown to black. Sterile flies are released by the hundreds of millions to suppress the invasive population. . Jiron LF, Soto-Manitiu J, Norrbom AL. This is in sharp contrast to some other serious fruit fly pests, such as Mediterranean fruit fly, Ceratitis capitata (Wiedemann), and oriental fruit fly, Bactrocera dorsalis Hendel, for which powerful male sex attractants are available and used in traps to detect populations early in the invasion process. Ageing can reduce the probability that individuals reproduce. Mexican ponche Navideño is a sweet, hot, fruit-salad of a drink. 1 X 3) and separated medially by approximately 2 X the length of 1 spiracle. [15], Larvae eat and burrow into the fruit that their mother laid them on. Oxon, UK. Greene CT. 1929. [1] The eradication of these flies from most of the US and Northern Mexico is largely due to the successful implementation of the sterile insect technique (SIT). 5 X width), with dorsal two angled upward and ventral one angled downward on each side of median. [3] After this period the male is fully sexually active. [2], A. ludens is native to Mexico and Central America and is a major pest to citrus and mango agriculture in Mexico, Central America, and the lower Rio Grande Valley. They hunt their prey using echolocation. This pheromone seems to stimulate the female fly. Photograph by Jack Dykinga, USDA. "Biodemography of a long-lived tephritid: Reproduction and longevity in a large cohort of female Mexican fruit flies, Animal and Plant Health Inspection Service, "Hernández-Ortiz V, Manrique-Saide P, Delfín-González H, Novelo-Rincón L. First report of Anastrepha compressa in Mexico and new records for other Anastrepha species in the Yucatan Peninsula (Diptera: Tephritidae). Drawing by Division of Plant Industry. [23] Other tactics deployed by the USDA include the use of preventative pesticide application and biocontrol tactics by releasing parasitoid wasps, which are natural A. ludens predators. [5] According to the USDA, A. ludens is the only important member of the Anastrepha genus that is subtropical instead of tropical and thus has a range much further North than most Anastrepha species. Pictorial key to fruit fly larvae of the family Tephritidae. A preliminary list of the fruit flies of the genus. 36 pp. 1989. Drawing by Division of Plant Industry. Figure 8. [6] They are frequently designated as an invasive species in Southern California and Arizona and pose a serious threat to Florida's grapefruit agriculture. The first comprehensive treatment of Anastrepha taxonomy, which remains fundamental and useful, is that of Stone (1942). [3], Larvae will feed on their host fruit for continuous periods of over 24 hours. 1944), including cacti, figs, bananas, tomatoes, peppers, squash and beans. The pest has since been detected in … Pharyngeal skeleton of larva. This ability and their polyphagous nature allows them to be able to survive in poor resource conditions better than other flies as they migrate to find a site with better resources. They penetrate the cactus with their beak-like mouthparts and feed on its juices, remaining immobile unless alarmed. The new fly finds a dry sheltered spot until it can unfold their wings. On a larger commercial scale, such as a citrus grove, host trees may be treated with bait spray as described above, and immigration of new adults can be minimized by removal of other host plants in a surrounding buffer area. [3] Females typically lay approximately 25-70 eggs a day. [4], While female and male A. ludens can live up to 11 and 16 months respectively under lab conditions, in nature their lifespans tend to be about a year. Female terminalia: ovipositor sheath 2.6-2.9 mm long, stout, tapering posteriorly, spiracles 1.05 mm from base. Their relatively long life span allows females to have a gross reproduction rate of up to 1600 offspring. 5. Acc. 1996. Dickens JC, Solis E, Hart WG. They usually catch flying prey in flight. [2] Larvae usually pupate on the ground but have also been observed to occasionally pupate inside its host fruit. [4] The Anastrepha genus is designated as one of three genera that pose the greatest risk to American agriculture. The Mexican fruit fly, Anastrepha ludens (Loew), is a pest of citrus, mangoes, and a variety of backyard tree fruits, from Mexico to Panama. [6] The Texas Department of Agracalture (TDA) advises anyone with citrus trees to pick fruits before they fall to the ground to help prevent the spread of the species. [7] Female adult A. ludens have a long ovipositor (3.35-4.7mm) and sheath relative to body size and are capable of laying more than 1,500 eggs in their lifetimes,[7] making A. ludens highly fecund. Wing band color is pale yellow in A. ludens and dark brown in A. suspensa. Incidence of the Mexican fruit fly, Anastrepha ludens (Loew), in Florida. They have a mesonotum that is 2.75-3.6 mm long and a wing span of 6.6-9.0 mm.[2]. Adult Occurrence: Most abundant in warmer months. [5], Currently, California, Arizona, Florida and most of northern Mexico are considered free of Mexican fruit flies and eradication efforts are taking place in Texas,[10][11] with some Texas quarantine areas having been successfully cleared and the quarantines lifted. The Mexican Fruit Fly (Anastrepha ludens) is a serious pest to various fruits, particularly citrus and mango. SIT is currently used in parts of Texas to control the species population.[10]. 52582," are present in the Florida State Collection of Arthropods. List taken from White and Elson-Harris (1992) and Hernandez-Ortiz (1992). The Mexican fruit fly also known as Anastrepha ludens and the Mexfly[1] is a species of fly of the Anastrepha genus in the Tephritidae family (fruit flies). [14], The life cycle begins when the adult female lays her eggs. Mating senescence and male reproductive organ size in the Mexican fruit fly.

Sexual development and mating behavior of the Mexican fruit fly. Five-year strategy plan 2008-2013 for fruit flies of Mexico. Exotic fruit flies, including the Oriental fruit fly (Bactrocera dorsalis), carambola fruit fly (B. caramboloe) and Mexican fruit fly (Anastrepha ludens) are highly invasive species that threaten Australia’s fruit production as well as our ability to export to other countries. CAB International. The Mexican fruit fly, Anastrepha ludens(Loew), is a very serious pest of various fruits, particularly citrus and mango, in Mexico and Central America. Mexican fruit fly was first found in Central Mexico in 1863, and by the early 1950s flies were found along the California-Mexico border. Mexican fruit fly larvae are transported widely in infested fruits. [3], The adult fly emerges from the pupal casing and the life cycle begins anew. Anal lobes usually bifid (each lobe split); buccal carinae 12 to 14; anterior spiracles usually with 18 tubules (rarely 12 to 18); caudal end with dorsal papillules in each pair as widely separated as in each pair of intermediate papillules (distance between D1 & D2 = I1 & I2), and "lateral" papillules apparently only "single" (papillule I3 not prominent); ventral papillules prominent; posterior spiracles elongated (ca. Internac. Mexican fruit fly and Caribbean fruit fly, Anastrepha suspensa (Loew), larvae (last instars) may be separated as follows: 1. What we consider "fruit flies" includes a number of small flies in the family Drosophilidae, such as the species Drosophila melanogaster (the common fruit fly) and Drosophila suzukii (the Asian fruit fly). Large numbers of Mexican free-tailed bats fly hundreds of meters above the ground in Texas to feed on migrating insects. Technology for the eradication programs used to maintain these zones is supported by research by the USDA-ARS laboratory in Weslaco, Texas, and Sanidad Vegetal laboratories in Mexico. Other families of bacteria have been found in Mexican fruit flies including Vibrionaceae, Bacillaceae, Micrococcaceae, and Pseudomonadaceae. [3], A. ludens males follow a lek mating strategy in which they provide no parental care for offspring. Agropec. A single specimen was detected in a multi-lure trap in Orlando in 2003, and an extensive survey program yielded no further specimens. Ebeling W. 1959. The anal lobe is usually bifid (each lobe split) , but sometimes entire (the anal lobe variation requires further study to determine if this represents one or two species, or a hybrid). Trapping is not a good method to estimate populations of this fruit fly. . Masters thesis. D. A. Berrigan. Adult female Mexican fruit fly, Anastrepha ludens (Loew). A. ludens has a broad host range and is a major pest, especially of citrus and mango (Mangifera indica) in most parts of its range.This species and Anastrepha obliqua are the most important pest species of Anastrepha in Central America and Mexico. The adult Mexican fruit fly is larger than a housefly, about 1.0 cm (0.38 inch) long. Orange, sweet limes, grapefruit, mangos, sapotes, peaches, guavas and plums are denied entry from Mexico into the United States by Federal Quarantine No. However, the discovery of adults in Florida has been surprisingly rare. Nonetheless, these specimens did not result in a configuration of the cephalo-pharyngeal skeleton exactly as published in illustrations of Phillips (1946) and Pruitt (1953). Larvae can be up to 12 mm in length. Mexican fruit fly, A. ludens has a much longer ovipositor (only 1.45 – 1.6 mm long in A. suspensa). Regional Sanidad. Adult: The adult Mexican fruit fly is 7–11 mm long, or slightly larger than a house fly (6–7 mm), and is mostly yellowish-brown in color. Wats. [4] Like other fruit flies, A. ludens need to consume a mixture of amino acids, minerals, carbohydrates, water, and vitamins in order to survive. [7], The Mexican fruit fly goes through four stages of development completing Holometabolous, or Complete Metamorphosis: egg, larvae, pupa, adult. Distribution 1996). A Mexican fruit fly infestation is not readily controlled on a small scale, such as by homeowners. [22] The effects of these bacteria on A. ludens are not well studied but it has been proposed by M. Aluja that A. ludens regurgitate internal bacteria onto their host and use the bacterial colonies as a protein source. Both research groups cooperate with USAD-APHIS Plant Protection and Quarantine and International Services departments in establishing protocols and executing sterile insect release programs. Caudal end of larva. In 1954, the fly species had spread westward as far as Hermosillo. Trypeta ludens (Loew 1973) The USDA implements a quarantine zone where wild flies are captured in the United States. Carroll LE, Wharton RA. The development is more rapid where comparatively higher temperatures prevail, and as a general rule, the shorter the period for fruit maturation the more rapid is the development of the larva. It is a frequent invader in southern California and Arizona. The female fly deposits eggs via her ovipositor into the fruit host. Larvae have an elongated cylindrical shape typical of fruit flies and are white in color. A. ludens, 2. 64 was enacted to prevent the shipment of certain fruits (mangos, sapotes, peaches, guavas, apples, pears, plums, quinces, apricots, mameys, ciruelas and citrus fruits, except lemons and sour limes) from several counties in Texas to other parts of the country except under certification by the U.S. Department of Agriculture. Various populations of each fruit fly species evidently exhibit variations in this and other characters that need to be taken into account. . Buccal carinae of larva. After the larvae matures to become an adult, 96% of A. ludens emerge from their burrow hole between 6 a.m. and 10 a.m. Mating calls of adult flies are observed mostly during late afternoons. The cephalo-pharyngeal skeleton has a relatively large convex mouth hook (length 2 X width), with hypostome of nearly equal width and the dorsal bridge is enlarged. (1990). More sterile flies are released in the area. The Mexican fruit fly, Anastrepha ludens (Loew), is a very serious pest of various fruits, particularly citrus and mango, in Mexico and Central America. San Salvador: Organ. Most species are characterized by their yellow to brown body and wing coloration, distinctive wing pattern of costal-, S-, and inverted V-bands (C, S, and V), and females with relatively long, tubular ovipositor sheaths. 1993. Adults are about 1/8 inch long and usually have red eyes. Unless introduced again from overseas or Mexico, this means the United States is now free of Mexican fruit flies (Nappo 2012). Bionomics and management of. Me… Males deposit their pheromones through their mouth and anus onto the underside of leaves, and they emit an aggressive song by quickly vibrating their wings. The present study investigates whether ageing influences the mating frequency of mass‐reared fertile and sterile Mexican fruit flies Anastrepha ludens (Loew). https://en.wikipedia.org/w/index.php?title=Anastrepha_ludens&oldid=995585888, Pages using multiple image with auto scaled images, Articles with failed verification from December 2020, Creative Commons Attribution-ShareAlike License.

Host Material: Decaying vegetation and animal matter. The caudal end has paired dorsal (D1 & D2) and intermediate (11 & 12) papillules, plus an indistinct I3; prominent L1 and V1; D1 & D2 acutely angled (ca. Mexican free-tailed bats are primarily insectivores. Fruit flies are common in homes, restaurants, supermarkets and wherever else food is allowed to rot and ferment. "Development, genetic and cytogenetic analyses of genetic sexing strains of the Mexican fruit fly, "Colonization of a Hybrid Strain to Restore Male, United States National Agricultural Library. [3], Female A. ludens will use olfactory and visual stimulus to find a good oviposition site. [6], As of October 2019, there are no active A. ludens quarantine zones in the USA. [18] Diachasmimorpha longicaudata, Doryctobracon crawfordi, Ganaspis pelleranoi, Biosteres giffardi, B. vandenboschi, and Aceratoneuromyia indica have been released by the governments of the US, Costa Rica, Mexico, Brazil, Argentina[failed verification] and Peru to biologically control A. ludens and other Anastrepha species populations. After mating, the fertilised female increases in size and gives birth to tiny nymphs. Other articles where Mexican fruit fly is discussed: fruit fly: …of this family include the Mexican fruit fly (Anastrepha ludens), which attacks citrus crops; the Oriental fruit fly (Dacus dorsalis), which infests many kinds of subtropical fruits; and the olive fruit fly (Dacus oleae), which destroys olives in the Mediterranean region. Figure 13. 1 X 5) and separated medially by approximately 3 X the length of 1 spiracle. The Mexican fruit fly is native to southern and central Mexico. Figure 7. They go on to attribute this genetic diversity to natural selection across the wide habitat range of the fly and to pest management practices. Journal of Agricultural Research 38: 489-504. Mexican fruit fly infestations; the latest was in 1992 in Los Angeles County. Drawing by Division of Plant Industry. Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. Summary of Invasiveness Top of page. Fruit Flies of Economic Significance: Their Identification and Bionomics. While grapefruits and oranges are preferred, other citrus fruits, pears, apples, and peach are also common hosts and thus food sources. [9], The US Department of Agriculture presumes that these flies were introduced to the USA through the import of larvae infested fruits.
