Oriental fruit fly (Bactrocera dorsalis)

The oriental fruit fly (Bactrocera dorsalis) is a highly destructive pest of fruit crops. It has a wide host range including nearly 500 fruits and vegetables, but is most commonly found attacking avocado, mango and papaya. Females live 1-3 months and can produce 1,500 eggs in her lifetime. She may lay up to 20 eggs in a single fruit. As the larvae develop, they cause severe feeding damage and rotting of the fruit, which is typical of most fruit fly pests.
