Featured creatures fact sheet: Mexican fruit fly, Anastrepha ludens (Loew) (Insecta: Diptera: Tephritidae). (17 July 2001). Eyes are reddish purple (fluoresce green, turning blackish within 24 hours after death). Distribution. Fruit fly is one of the most serious pests of citrus. United States Department of Agriculture Bulletin 536: 1-119. Caribbean fruit flies found in citrus are native to the islands of the same name but have migrated over time to afflict groves worldwide. Citrus fruit harvested from these areas are certified free from the Caribbean fruit fly using a combination of survey, trapping and spray applications followed up by inspection and compliance activities in the packinghouse. Figure 15. Gradually, the wild flies can only find sterile flies to mate, the wild population is eradicated. If collected larvae must be killed, they should be placed in hot water and then transferred to 70% isopropenol. There is a wide brownish yellow band across middle of wing.

Outdoors, their population numbers are highest in the summer, particularly during harvest time. Peach infested with larvae of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). Several females may use the same deposition hole with 75 or more eggs clustered in one spot. 1918. They can fly short distances, but winds may carry them a mile or more away. The anterior buccal carinae are usually nine to 10 in number. Bananas are harvested green and papaya at colour break. During June–August 2010, the largest outbreak since the 1997-1998 infestations was discovered and eradicated in Palm Beach County in the Boca Raton area (FDACS 2010a, 2010c); California in 1975, and periodically since 1980. (http://entnemdept.ufl.edu/creatures/fruit/tropical/mexican_fruit_fly.htm). Caribbean fruit fly, Anastrepha suspensa Mexican fruit fly, A. ludens has a much longer ovipositor (only 1.45 – 1.6 mm long in A. suspensa). Life history of the Mediterranean fruit fly from the standpoint of parasite introduction. Lack of fruit for three to four months reduces the population to a minimum. The female's extended ovipositor is 1.2 mm long. The improved version of the McPhail trap uses a combination of three chemicals to attract male and female fruit flies. Larval identification is based primarily on characters of mature 3rd instar larvae. 2012. Getty. Photograph by USDA. Studies in Hawaiian fruit flies. Females usually die soon after they cease to oviposit. Nectarines can come under attack . Figure 4. 2012. Photograph by USDA. USDA-APHIS, in cooperation with threatened states, has established action plans that go into effect when fruit flies are trapped and reported (USDA 2008). Photograph by USDA. 7.4.1.1.1 . The males are easily separated from all other members of this family by the black pointed expansion at the apex of the anterior pair of orbital setae. Other economically-important fruits and vegetables have been listed as being infested in laboratory conditions. Larval Diagnosis The primary diagnostic characters for Mediterranean fruit fly larvae involve the anterior spiracles, the buccal carinae, and the prominent subspiracular tubercles of the caudal end. But when given the choice, these annoying pests actually prefer citrus like oranges, limes, and lemons. Phytosanitary Alert System. Photograph by Scott Bauer, USDA. Fruit is placed in heavy plastic bags and removed to a local landfill to be buried. Figure 21. United States Department of Agriculture, Washington, D.C. Back EA, Pemberton CE.

Eggs are deposited under the skin of fruit which is just beginning to ripen, often in an area where some break in the skin already has occurred. It is yellow in colour with dark brown to black markings on the segment where the wings are attached. Mexican fruit fly, A. ludens has a much longer ovipositor (3.35 - 4.7 mm long in A. ludens). The Mediterranean fruit fly attacks more than 260 different fruits, flowers, vegetables, and nuts. Thermal responses in the citrus fruit fly, Dacus tsuneonis: evidence for a pupal diapause. The parastomium is prominent. Most previous illustrations of the cephalo-pharyngeal skeleton of the species have not shown the pharyngeal plate hood, and details of the illustrations also vary among themselves (see Greene 1929, Phillips 1946). The lower corners of the face have white setae. Miscellaneous Publications, No. When the eggs hatch, the larvae promptly begin eating. Berg GH. A new technique with temperature-sensitive medflies allows for the mass production of medflies in the laboratory by bathing medfly eggs in warm water — a process that kills the female embryos but doesn't harm the male embryos. The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is one of the world's most destructive fruit pests. The pharyngeal skeleton is distinctive in overall configuration, particularly the enlarged subhypostomium of the hypostomium (posterior to each mouth hook). Ripe fruit is likely to be more juicy, and such fruits often are associated with a high mortality of eggs and young larvae. Morphological - Adult . Cooperative Economic Insect Report 25: 825-839.

Caudal end of larva of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). Characters of the larvae and pupae of certain fruit flies. Some hosts have been recorded as medfly hosts only under laboratory conditions and may not be attacked in the field. Adults die within four days if they cannot obtain food. Internac. Egg: The egg is very slender, curved, 1 mm long, smooth and shiny white. The anterior spiracles have the tubule edge relatively straight dorsally and the tubule number usually is nine to 10, although it can be from seven to 11. Larvae of fruit flies.

Joint cooperative Mediterranean fruit fly eradication project. Fruit Fly, common name for two families of true (two-winged) flies, the larvae of which feed on fresh or decaying vegetable matter. The color is yellowish with brown tinge, especially on abdomen, legs, and some markings on wings. Larvae burrow into the pulp of developing fruit and leave through a large exit hole. Papadopoulos NT. Larval life may be as short as six to 10 days when the mean temperatures average 77 to 79°F (25 to 26.1°C). Once an adult Mediterranean fruit fly is positively identified, the number of baited traps throughout that area is greatly increased to capture the flies and remove them from the environment, and to serve as a monitoring tool for the effectiveness of the eradication program. Fruit Stripping: Fruit will be stripped from all host trees on a known larval properties and within 200 meters (656 feet). Graphic by Division of Plant Industry.

Wings, usually held in a drooping position on live flies, are broad and hyaline with black, brown, and brownish yellow markings. These are shorter at the head end, and lengthen progressively towards the rear end. True fruit flies, such as the house fly-sized apple maggot, have intricate, often colorful wing patterns by which females recognize males of their species. Larger than a housefly, 7 - 10 mm (0.28 - 0.39 in.) There are 18 pairs of short waxy filaments around the margin of the body. Photograph by Division of Plant Industry. 2001).

It is recorded from Australia (New South Wales, Northern Territory, Queensland, and Victoria), French Polynesia, New Caledonia, and Pitcairn. The larvae feed upon the pulp of host fruits, sometimes tunneling through it and eventually reducing the whole to a juicy, inedible mass. Proceedings of the Florida State Horticultural Society 70: 67-69. Fully grown larvae, when the surrounding air temperature is warm, flex and "jump" repeatedly as much as 25 mm when removed from fruit. The dye proved to be as effective as malathion-bait sprays and might be a safe, effective alternative to previously used aerially-applied malathion insecticide baits. 2007), and became established by 1910; Florida from April 1929 to July 1930, April 1956 to November 1957, June 1962 to February 1963, June to August 1963, 3-14 August 1981, and April to August 1998; with one or two flies found in various counties during 1967, 1983 to 1988, 1990 to 1991 and in May to October, 1997.
