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.
