Anastrepha obliqua (Macquart) - (West Indian fruit fly)
This is a common and polyphagous fruit fly in Central and South America, except for Chile and southern Argentina. The main host fruits are mangoes and different Spondias species. However, many other common tropical and subtropical fruits are also attacked like guava, carambola or citrus. For infested countries, the actual damage caused by the fly is small compared to the losses in fruit exports. In Brazil only 2% of the fruit production can be exported, mainly due to fruit flies. Infested fruits are difficult to recognize unless they are opened. A. obliqua is frequently intercepted by quarantine and several eradication campaigns have been conducted in the southern U.S. Eggs are usually laid singly inside mature green fruits. The development from egg to adult lasts around 1-2 months and there are 6-7 generations per year. Like for other fruit flies, the main risk is spread through infested fruits. However, the adult is also a good flier and can travel distances of more than 100 km.
