This is thought to be due to larger males singing better mating songs and depositing more sperm into females. 1993. Drawing by G. J. Steck and B. D. Sutton, Division of Plant Industry. 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. [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. After mating, the fertilised female increases in size and gives birth to tiny nymphs. [20] A 2014 genetic study of A. ludens concluded that "A. ludens populations are genetically diverse with moderate levels of differentiation." Sterilization of fruit before shipment from quarantined areas is required. Figure 12. Adults may be very long-lived, up to 11 months, and highly fecund, laying 1,500 eggs or more. 29-54. List taken from White and Elson-Harris (1992) and Hernandez-Ortiz (1992). They have a mesonotum that is 2.75-3.6 mm long and a wing span of 6.6-9.0 mm.[2]. The first comprehensive treatment of Anastrepha taxonomy, which remains fundamental and useful, is that of Stone (1942). ARS Program on, Steck GJ, Carroll LE, Celedonio-H H, Guillen-A J. [8] A. ludens were rare in Costa Rica until the 1990s when they suddenly appeared on citrus plants. 30°) and I3 is almost equidistant from L1 and I2. Larval movement is dictated by the ripeness of the host fruit. 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. The pest has since been detected in … Photo by Jeffrey Lotz, Division of Plant Industry. Me… Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. The females, wingless and about 5 mm (0.20 in) long, cluster on cactus pads. [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. [14], The life cycle begins when the adult female lays her eggs. 1990. Figure 8. Larval development requires approximately three to four weeks, depending largely upon temperature conditions during these periods of development. Clark RA, Steck GJ, Weems Jr HW. 1996). This is applied as fine droplets to host plant foliage where adults feed. (1944); see also extensive references in Aluja (1994). Cochineal insects are soft-bodied, flat, oval-shaped scale insects. [3], A. ludens males follow a lek mating strategy in which they provide no parental care for offspring. In addition they found high levels of inbreeding in the species. Ideal territories for males are under the leaves of trees that produce citrus fruit. Eggs are usually laid in groups of about ten and hatch in six to 12 days. They have been observed landing on potential host fruit and walking around while headbutting the fruit. 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. 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. [2] It is an invasive species to the US. 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). 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. 1988. Search for more papers by this author. The Mexican fruit fly, Anastrepha ludens(Loew), is a very serious pest of various fruits, particularly citrus and mango, in Mexico and Central America. US Department of Agriculture, APHIS Fact Sheet, Mexican Fruit Fly, Doc. More sterile flies are released in the area. Sterile flies are released by the hundreds of millions to suppress the invasive population. Masters thesis. It is a frequent invader in southern California and Arizona. 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. [17], The main natural enemies of A. ludens are parasitoid wasps, specifically in the families Branconidae and Ichneumonidae. 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. Reyesâ Hernández M, Diana Pérezâ Staples. However, adults are highly mobile and move easily from any nearby untreated trees back to treated trees after a few days. 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. For sterile insect techniques to control pests, the sterile insect must be attractive. Once the female makes her decision to lay eggs, she will bore into the fruit and deposit eggs. The Mexican fruit fly, A. ludens, is typical in appearance to other members of the genus Anastrepha, but notable for the female's long ovipositor and sheath relative to its body size. 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. 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. Fruit Flies of Economic Significance: Their Identification and Bionomics. 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. It is closely related to the Caribbean fruit fly Anastrepha suspensa, and the papaya fruit fly Anastrepha curvicauda. 5. Orange, sweet limes, grapefruit, mangos, sapotes, peaches, guavas and plums are denied entry from Mexico into the United States by Federal Quarantine No. [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. J. R. Carey. SIT is currently used in parts of Texas to control the species population.[10]. The body color is a pale orange-yellow with two to three whitish stripes along the thorax. [3], Female A. ludens will use olfactory and visual stimulus to find a good oviposition site. Identification of Fruit Fly Larvae Frequently Intercepted at Ports of Entry of the United States. [7], The Mexican fruit fly goes through four stages of development completing Holometabolous, or Complete Metamorphosis: egg, larvae, pupa, adult. U.S. 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". This pheromone seems to stimulate the female fly. University of Florida, Gainesville. Figure 3. Mexican Fruit Fly - In grapefruit as well as many other fruits, one female Mexican fruit fly 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 - Jack Dykinga, USDA. 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 Lotz, Division of Plant Industry their breeding site in Mexico, this means the United States except.
