Mediterranean Fruit Fly

 

(Ceratias capitata), an insect of the family Trypetidae, a dangerous crop pest. The body is 4.5 mm long. The mottled wings are marked with dark noncontinuous bands. The Mediterranean fruit fly is common in many countries of Europe, Asia, Africa, the Americas, Australia, and Oceania. It does not occur in the USSR, but it is an object of quarantine, since its larvae are easily transported with various fruits. The fly is polyphagous, damaging more than 70 plant species (for example, apricot, peach, orange, mandarin, apple, pear, grape, and tomato). The female deposits eggs on the skin of ripe fruit; the larvae hatch one or two days later and feed on the fruit for two to three weeks, causing it to rot. The number of generations varies with climatic conditions. Quarantine measures in the USSR and other countries that import citrus fruits largely consist of limiting imports to the winter and disinfecting fruits by heat or chemical agents.

As noted above, relative to the fresh lures, medfly captures were significantly lower in traps baited with plugs weathered for 8, 10, or 12 wk, whereas trimedlure content was < 0.4 g over these intervals.
It now also contributes to Medfly control (Wang, Messing, Bautista, et al.
Some recommendations on how to mitigate the specific threats given (ie, Paederus beetles, Medfly, Rift Valley fever) were presented, however, all military personnel can mitigate vector-borne disease threats by taking relatively simple actions.
"Here, we present the first alternative, radiation-free, reproductive sterility system for medfly based on transgenic embryonic lethality," said Wimmer.
Live medflies were confirmed in separate shipments of clementines from Spain in 2001, prompting USDA to amend regulations governing their importation and the cold treatment of fresh produce from all known medfly regions, Subsequent analysis by USDA's Animal and Plant Health Inspection Service suggested that the specified duration of treatment may not have achieved satisfactory control; therefore, USDA extended the required length of the treatment time.
Large-scale forces also play symbolic and social roles: the film is bookended by helicopters spraying the city during the Medfly infestation of 1990 (14) and a minor earthquake that unify all the characters under what Michael Davis has called L.A.'s "ecology of fear." Another force that keeps families together throughout the film is a host of minor black characters embodying an "Africanist presence" (15) that presses inwards from the margins of the interconnected plots and settings.
Much of the search for medfly detection and control techniques are focused on mating behavior and sexual communication signals, i.e., chemical lures or shape and color cues, being efficient and highly selective.
What had prompted this extraordinary demonstration was the discovery of a single medfly in the Port of Long Beach, some 20 miles south of Los Angeles.
The new requirements include provisions for the clementines to be grown in accordance with a Mediterranean fruit fly management programme set up by the Spanish Government, that they be subject to an inspection regime that includes fruit cutting before and after cold treatment, and that they meet other conditions designed to protect against the introduction of the Medfly.
An example is provided by an evaluation of the Mediterranean Fruit Fly (Medfly) Exclusion and Detection Program.
Making its home in the southern United States, the Mediterranean fruit fly (Medfly) is one of the world's most destructive fruit pests.
