The Medfly originated in Africa. It has since spread throughout the Mediterranean region, southern Europe, the Middle East, western Australia, South and Central America, and Hawaii. In general, it is found in most tropical and subtropical areas of the world.
Ceratitis capitata is a highly invasive species. It has a high economic impact, affecting production, control costs and market access.
The adult medfly is 4 to 5mm long, (about two-thirds the size of a housefly). The general color of the body is yellowish with a tinge of brown, especially the abdomen, legs, and some of the markings on the wings. The oval shaped abdomen is clothed on the upper surface with fine, scattered black bristles, and has two narrow, transverse, light colored bands on the basal half. The female can be distinguished by its long ovipositor at the apex of the abdomen.
