First report of Anastrepha compressa in Mexico and new records for other Anastrepha species in the Yucatan Peninsula (Diptera: Tephritidae). Animal and Plant Health Inspection Service, Fruits and Vegetables Import Requirements (FAVIR). 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. Mexican fruit fly is one of the world's most destructive invasive pests, attacking more than 40 different kinds of fruits and vegetables. Me… [3], A. ludens have 12 chromosomes and most cells are diploid. The gut bacteria may also play a role in digestion and detoxification of chemicals. In the event of a quarantine, some of the commodities affected include: Guava, cherimoya, passionfruit, coffee, and many other subtropical fruits It is a frequent invader in southern California and Arizona. [3], Larvae will feed on their host fruit for continuous periods of over 24 hours. [2] Larvae usually pupate on the ground but have also been observed to occasionally pupate inside its host fruit. Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. The Caribbean fruit fly, Anastrepha suspensa (Loew), has also been called the Greater Antilliean fruit fly, the guava fruit fly and the Caribfly. Texas residents in McAllen and Laredo fruit fly quarantines can help stop the spread of invasive fruit flies: Fresh produce, fruit and vegetables brought into the U.S. or across state borders without inspection. Traveling north from Mexico to … [8] A. ludens were rare in Costa Rica until the 1990s when they suddenly appeared on citrus plants. When they have reached optimal size and environmental conditions are right, the mature larvae emerge from the fruit into the soil and begin to pupate. 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. See your browser's documentation for specific instructions. Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. This invasive fruit fly does not harm humans or animals but it poses a serious threat to the Texas citrus industry. It is a frequent invader in southern California and Arizona. [14], The life cycle begins when the adult female lays her eggs. The host list includes: Javascript is disabled in this browser. Here's how you know. The rate at which they mature is directly related to ambient environmental factors such as temperature and humidity.

[3] A. ludens female reproductive potential has been shown to be affected by male-female contact. The Mexican fruit fly is currently found in parts of Texas and California. While inside the fruit, the larvae continue to grow and develop through 3 larval instars. 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. Anastrepha ludens (Loew)--Some of the natural enemies of oriental and Mediterranean fruit flies have shown activity on Anastrepha spp. [4] Like other fruit flies, A. ludens need to consume a mixture of amino acids, minerals, carbohydrates, water, and vitamins in order to survive. Provided assistance to PPQ canine handlers from Newnan, Georgia in training detector dogs for locating Mexican fruit fly larvae in citrus fruit. Mexican fruit fly was first found in Central Mexico in 1863, and by the early 1950s flies were found along the California-Mexico border.
