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. Figure 8. Host preferences vary in different regions. Development in egg, larval, and pupal stages stops at 50°F (10°C). The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is one of the most damaging horticultural insect pests. Drosophila (/ d r ə ˈ s ɒ f ɪ l ə, d r ɒ-, d r oʊ-/) is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. (1992) (60% on kumquat). It occurs in parts of Queensland, New South Wales, Victoria and the Northern Territory. Males often show sexual activity four days after emergence, and copulation has been observed five days after emergence. This study used a low-oxygen/high-nitrogen bioassay to control C. capitata . Photograph by USDA. The light areas have very fine white bristles. Incidence of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), in Florida, 1929-1998. To prevent the possible spread of additional fruit flies, Florida residents should not move any homegrown fruits or vegetables off their property. 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. Eyes are reddish purple (fluoresce green, turning blackish within 24 hours after death). Although Mediterranean fruit fly adult and third-instar larvae can usually be identified and distinguished from other species by morphological keys, it is often difficult or impossible to identify or distinguish this species from other tephritids by using material from other stages of development. Posterior spriacles (left side) (after Phillips 1946) of a larva of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). The yield of mass rearing can be influenced by micro-organisms. Older version of trap used to capture adults of the Adult Mediterranean fruit fly, Ceratitis capitata (Wiedemann). The Mediterranean fruit fly is one of the most common known pests in the agricultural industry. Because of its wide distribution over the world, its ability to tolerate cooler climates better than most other species of fruit flies, and its wide range of hosts, it is ranked first among economically important fruit fly species. The apex of the wing's anal cell is elongate. Photograph by Scott Bauer, USDA. Figure 24. Adults may live over a year and and lay 800 eggs. Oxon, UK. Reinfestations in the same areas leads some experts to believe the California infestion was never eradicated but was instead reduced to subdetectable levels that periodically resurface (Dawson et al. Young fruits become distorted and usually drop. The Mediterranean fruit fly has been recorded infesting over 200 different types of fruits and vegetables. In Florida, Inspectors from the Department of Agriculture and Consumer Services-Division of Plant Industry continually monitor the traps for the appearance of pest fruit flies. Mediterranean fruit fly Ceratitis capitata Wiedemann is species of invasive pest that affects fruit production and export worldwide. 13 pp. When Medfly larvae first hatch they are about 1mm long before growing to 8mm and leaving the fruit to pupate in the soil. HOSTS: The Mediterranean fruit fly attacks more than 260 different fruits, flowers, vegetables, and nuts. Back and Pemberton (1915) noted that this period may be increased to at least 19 days when the daily temperature means drop to about 69 to 71°F (20.6 to 21.7°C). Mediterranean fruit fly.
