Males mating strategy involves claiming a territory and defending it from other males through sounds and physical actions. 36 pp. Clark RA, Steck GJ, Weems Jr HW. Berg GH. It is a frequent invader in southern California and Arizona. The Mexican fruit fly, Anastrepha ludens(Loew), is a very serious pest of various fruits, particularly citrus and mango, in Mexico and Central America. 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. By 1927, Mexican fruit flies were infecting citrus farms in lower Rio Grande Valley of Southern Texas and threatening farmland in California, Texas, Florida, and Arizona. 1942. A. suspensa prey on many of the same fruits in the same regions where A. ludens primarily reside as well. The female is distinguished by a long and slender ovipositor which is used to deposit eggs beneath the skin of the host fruit. 1944), including cacti, figs, bananas, tomatoes, peppers, squash and beans. Department of Entomology, University of California, Davis, CA 95616, USA. U.S. Caudal end of larva. Buccal carinae of larva. 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. [9], The US Department of Agriculture presumes that these flies were introduced to the USA through the import of larvae infested fruits. 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. 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. 1990. Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. Mexican fruit fly, A. ludens has a much longer ovipositor (only 1.45 – 1.6 mm long in A. suspensa). Anal lobes always entire; buccal carinae 8; anterior spiracles with 12 to 13 tubules; caudal end with dorsal papillules in each pair distinctly closer together than those of each pair of intermediate papillules (distance between D1 & D2 half that of 11 & 12), and "lateral" papillules with a distinct "pair" of papillules on each side of the posterior spiracles (13 prominent); ventral papillules usually indistinct; posterior spiracles of average length (ca. They have been observed landing on potential host fruit and walking around while headbutting the fruit. Acc. However what makes them most dangerous is their universality for plant hosts, the fruit flies can lay their eggs in anything from cashews to peppers to citrus fruits. The Mexican fruit fly is indigenous to Mexico and much of Central America as far south as Costa Rica. The gut bacteria may also play a role in digestion and detoxification of chemicals. Egg and larval stages inside the fruit are safe from insecticidal treatments. Figure 8. The bats eat moths, beetles, dragonflies, flies, true bugs, wasps, and ants. Photograph by Jack Dykinga, USDA. [14], The life cycle begins when the adult female lays her eggs. . Florida Entomologist", 10.1653/0015-4040(2002)085[0389:FROACI]2.0.CO;2, "Fruit Flies of Economic Significance: Their Identification and Bionomics", "Control of the turpentine border in the stores region". Mexican fruit flies, Anastrepha ludens (Loew), laying eggs in grapefruit during a laboratory test. Most species in the Anastrepha genus including A. ludens have a distinctive yellow and brown coloration of the body and wings. Orange, sweet limes, grapefruit, mangos, sapotes, peaches, guavas and plums are denied entry from Mexico into the United States by Federal Quarantine No. Management Methods: Residual and … ARS Program on, Steck GJ, Carroll LE, Celedonio-H H, Guillen-A J. This is thought to be due to larger males singing better mating songs and depositing more sperm into females. While grapefruits and oranges are preferred, other citrus fruits, pears, apples, and peach are also common hosts and thus food sources. Identification of Fruit Fly Larvae Frequently Intercepted at Ports of Entry of the United States. [3], A. ludens have 12 chromosomes and most cells are diploid. 1979. 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. Drawing by Division of Plant Industry. [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 adult stage is susceptible to control, usually by a short-lived bait comprised of a contact insecticide mixed with protein and carbohydrate. [16], A. ludens have been observed migrating about 135 km from their breeding site in Mexico to farms in southern Texas. 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. Oxon, UK. 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. Physiological Entomology, 01 Mar 2017, 42(1): 26-35 DOI: 10.1111/phen.12160 AGR: IND605718309 . University of Florida, Gainesville. The front portion of the body is tan and the rear portion is black. [2] It is an invasive species to the US. [20] A 2014 genetic study of A. ludens concluded that "A. ludens populations are genetically diverse with moderate levels of differentiation." Greene CT. 1929. However, with the eradication of the Mexican fruit fly in the United States in 2012, this quarantine is no longer in effect (NAPPO 2012). [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. 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 adult Mexican fruit fly is larger than a housefly, about 1.0 cm (0.38 inch) long. . [2] The species exhibits high fecundity and relatively long lifespans compared to other species of fruit flies. Drawing by Division of Plant Industry. [19] D. longicaudata and D. crawfordi have been established as the most efficient at controlling population size for this species of flies. Drawing by G. J. Steck and B. D. Sutton, Division of Plant Industry. 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). Photo by Jeffrey Lotz, Division of Plant Industry. [4] These flies are known to be able to go through period of estivation. Mexican free-tailed bats are primarily insectivores. Mating senescence and male reproductive organ size in the Mexican fruit fly. Figure 6. [3] A. ludens female reproductive potential has been shown to be affected by male-female contact. Robacher D, Magan RL. [15], Larvae eat and burrow into the fruit that their mother laid them on. Bionomics and management of. [4], Most species in the Anastrepha genus including A. ludens have a distinctive yellow and brown coloration of the body and wings. After mating, the fertilised female increases in size and gives birth to tiny nymphs. They go on to attribute this genetic diversity to natural selection across the wide habitat range of the fly and to pest management practices. 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. [3] After this period the male is fully sexually active. They have a mesonotum that is 2.75-3.6 mm long and a wing span of 6.6-9.0 mm.[2]. When fully grown, the larvae emerge through conspicuous exit holes, usually after the fruit has fallen to the ground, and pupate in the soil. The interspiracular processes (hairs) are mostly branched distally. Memoirs of the American Entomological Society 12: 161. 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. 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). Aluja M. 1994. (1993). [5] There has been at least one Mexfly quarantine in Texas on an annual basis for over 80 years. 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). . Previously, a single fly was captured in a McPhail trap in Sarasota in 1972 (Clark et al. [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. The Mexican fruit fly, Anastrepha ludens (Diptera: Tephritidae) is a long-lived species, with an average life expectancy of approximately 50 d under laboratory conditions (Carey et al., 2005). The anterior spiracles are slightly asymmetrical, with a median depression, with 18 tubules usually present (rarely 12 to 18). The adult female typically oviposits in citrus and other fruit at the time when the fruit begins to show color. 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. [24], North American Plant Protection Organization, "Fruit Fly Exclusion and Detection Strategic Plan FY 2019-2023". 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. 1996. U.S. Habitat: The Mexican fruit fly has been an especially particular problem for the state of Florida because the fly has a strong preference of laying eggs in grapefruit. In 1954, the fly species had spread westward as far as Hermosillo. [3], Larvae will feed on their host fruit for continuous periods of over 24 hours. For sterile insect techniques to control pests, the sterile insect must be attractive. [3], Female A. ludens will use olfactory and visual stimulus to find a good oviposition site. Larval movement is dictated by the ripeness of the host fruit. 1993. Gainesville: University of Florida. The female fly can lay over 1500 eggs in its lifetime. Wing band color is pale yellow in A. ludens and dark brown in A. suspensa. Anal lobes of larva. 1994. Other families of bacteria have been found in Mexican fruit flies including Vibrionaceae, Bacillaceae, Micrococcaceae, and Pseudomonadaceae. Fruit Flies Follow Fermenting Fruit . [7], The Mexican fruit fly goes through four stages of development completing Holometabolous, or Complete Metamorphosis: egg, larvae, pupa, adult. Present: AZ, CA, FL, TX Figure 5. Pictorial key to fruit fly larvae of the family Tephritidae. 1988. A Mexican fruit fly infestation is not readily controlled on a small scale, such as by homeowners. Search for more papers by this author. [3], The larval stage lasts for 3–4 weeks, depending on the temperature and other conditions. [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. Figure 1. Anastrepha ludens is a well-defined and clearly distinct species, although there is a possibility of a separate but nearly indistinguishable form in the extreme southern part of its distribution in Costa Rica (Jiron et al. Subtropical Fruit Pests. 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. Dose Figure 9. All varieties of citrus except lemons and sour limes are attacked. Incidence of the Mexican fruit fly, Anastrepha ludens (Loew), in Florida. Acrotoxa ludens Loew Extensive further details on the biology and ecology of the Mexican fruit fly are given by Baker et al. Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. [3], Male A. ludens exhibit lek mating and thus do not provide any care for offspring outside of fertilizing the egg. The length of mesonotum is 2.45–3.57 mm. A preliminary list of the fruit flies of the genus. Caribbean fruit fly, Anastrepha suspensa. It is closely related to the Caribbean fruit fly Anastrepha suspensa, and the papaya fruit fly Anastrepha curvicauda. The adult A. ludens is 7–11 mm long, or slightly larger than a common house fly. The first comprehensive treatment of Anastrepha taxonomy, which remains fundamental and useful, is that of Stone (1942). Posterior spiracles (left group) of larva. Federal Quarantine No. Regional Sanidad. 1989. A. ludens prefers laying eggs in grapefruits and oranges, but many other hosts have been recorded including: It has been experimentally shown that A. ludens choose oranges and grapefruit over other hosts but in the absence of these fruits will deposit larvae on any of the above hosts. 1 X 3) and separated medially by approximately 2 X the length of 1 spiracle. Figure 10. While inside the fruit, the larvae continue to grow and develop through 3 larval instars. Wats. (1944); see also extensive references in Aluja (1994).

The Mexican fruit fly, Anastrepha ludens (Loew), is a pest of citrus, mangoes, and a variety of backyard tree fruits, from Mexico to Panama. [2] Larvae usually pupate on the ground but have also been observed to occasionally pupate inside its host fruit. 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. 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. 5 X width), with dorsal two angled upward and ventral one angled downward on each side of median. Sterilization of fruit before shipment from quarantined areas is required. US Department of Agriculture, APHIS Fact Sheet, Mexican Fruit Fly, Doc. [3], Female A. ludens exhibit mate choice and tend to prefer to mate with larger males. Mexican fruit fly and Caribbean fruit fly, Anastrepha suspensa (Loew), larvae (last instars) may be separated as follows: 1. 5. [4] The Anastrepha genus is designated as one of three genera that pose the greatest risk to American agriculture. 30°) and I3 is almost equidistant from L1 and I2. Masters thesis. Link Coll., S.P.B. 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. 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 rate at which they mature is directly related to ambient environmental factors such as temperature and humidity. Still other fruits and vegetables have been infested under laboratory conditions (Baker et al. Figure 4. Large numbers of Mexican free-tailed bats fly hundreds of meters above the ground in Texas to feed on migrating insects. They have a mesonotum that is 2.75-3.6 mm long and a wing span of 6.6-9.0 mm. They usually catch flying prey in flight. 1 X 5) and separated medially by approximately 3 X the length of 1 spiracle. Biting midges are flies (Order Diptera) in the family Ceratopogonidae, which includes over 4, 000 species in 78 genera worldwide. Pharyngeal skeleton of larva. Females have a relatively long life spans of up to 11 months. 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. Unless introduced again from overseas or Mexico, this means the United States is now free of Mexican fruit flies (Nappo 2012). The ovipositor is 3.35–4.7 mm long. 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. 52582," are present in the Florida State Collection of Arthropods. Adults may be very long-lived, up to 11 months, and highly fecund, laying 1,500 eggs or more. Figure 3. The female fly deposits eggs via her ovipositor into the fruit host. Grapefruit is the preferred host, with oranges second. Adult: The adult fruit fly is rather small to medium sized; yellow brown, thorax patterned with black. Common fruit fly is an important organism and widely used for genetic analysis in modern biology because it has only four pairs of chromosomes. The Sterile Insect Technique is used in maintaining a fly-free zone in Mexico, Texas and California. The eggs hatch 6–10 days later and then enter their second stage of development, the larval stage. 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. Upon emerging, the tiny larvae continue to feed near the surface of the fermenting mass. Trapping is not a good method to estimate populations of this fruit fly. Males live even longer than females, up to 16 months. Internac. Photo by Jeffrey Lotz, Division of Plant Industry. The females, wingless and about 5 mm (0.20 in) long, cluster on cactus pads. The adult A. ludens is 7–11 mm long, or slightly larger than a common house fly. 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. 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. While not a preferred host, avocado also is attacked. Photograph by Jeff Lotz, Division of Plant Industry. The cephalo-pharyngeal skeleton is not usually examined in routine identifications because the larval specimen must be dissected before this character can be examined. fruit fly Ceratitis capitata 225 Oriental fruit fly Bactrocera dorsalis 250 Min. GF-120 NF Naturalyte Fruit Fly Bait is a group 5 insecticidal bait that provides an effective solution against nuisance flies.

The newly hatched larvae eat and burrow into the pulp of the fruit, taking on the color of their food so that when small they are overlooked easily. Figure 11. This page was last edited on 21 December 2020, at 21:25. The pest has since been detected in … D. A. Berrigan. [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. Wing of the Mexican fruit fly, A. ludens. Once the female makes her decision to lay eggs, she will bore into the fruit and deposit eggs. [3], During pupation, the larvae undergo complete metamorphosis to change into adult flies. 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. For two species of Anastrepha fruit flies, the West Indian fruit fly (A. obliqua) and the Mexican fruit fly (A. ludens), the size of the male in one was important for a female’s selection, while size did not matter in the other species. Fruit flies are common in homes, restaurants, supermarkets and wherever else food is allowed to rot and ferment. [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. 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. There are 12 to 14 anterior buccal carinae. Wing of the Caribbean fruit fly, A. suspensa. The body color is a pale orange-yellow with two to three whitish stripes along the thorax. It is a frequent invader in southern California and Arizona. 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 Carroll LE, Wharton RA. The Mexican fruit fly prefers living near citrus and other fruits, which act as hosts where the female can lay her eggs. 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.
