Pest Alert: Oriental Fruit Fly in Miami-Dade

MIAMI, Fla.—Florida Commissioner of Agriculture Adam H. Putnam today declared a state of agricultural emergency due to the Oriental Fruit Fly infestation in Miami-Dade County. The Oriental Fruit Fly is considered one of the most serious of the world’s fruit fly pests due to its potential economic harm. It attacks more than 430 different fruits, vegetables and nuts, including: avocado, mango, mamey, loquat, lychee, longon, dragon fruit, guava, papaya, sapodilla, banana and annona. The fruit flies lay their eggs in host fruits and vegetables. Since the first detection of the Oriental Fruit Fly on Aug. 26, 2015 in Miami-Dade County, a total of 158 flies have been detected, specifically in the Redland area (156), Kendall (1) and Miami (1).

The oriental fruit fly, Bactrocera dorsalis (Hendel), is a very destructive pest of fruit in areas where it occurs. It is established in numerous areas in Asia, and is often intercepted in the United States, sometimes establishing infestations that were previously eradicated. This fly lays its eggs in fruit, where larvae hatch and eat the fruit, ruining it.

The adult is noticeably larger than a house fly and usually has prominent yellow and dark brown to black markings on the thorax.
