As a Mediterranean fruit fly infestation falls under the control of Florida's regulatory agency - the Department of Agriculture and Consumer Services (FDACS) and its Division of Plant Industry (DPI), there are no University of Florida management recommendations. Plus treatment strategies change in an environment of public concern about aerial application of insecticidal baits.

For the 2010 infestation, the following treatments are being used by FDACS-DPI and the USDA (FDACS 2010b):

Foliar Spot Treatments: Spraying trees with Spinosad (product FG-120 NF Naturalyte Fruit Fly Bait) which is an insecticide derived from a naturally occurring soil organism. Spraying will take place in the core area of a positive find and extend out 1-1/2 miles.

Soil Drenching: The soil under host trees with fruit known or suspected to be infested with medfly larvae and host trees under adjacent properties will be treated.

Fruit Stripping: Fruit will be stripped from all host trees on a known larval properties and within 200 meters (656 feet). Fruit is placed in heavy plastic bags and removed to a local landfill to be buried.

Sterile Fruit Fly Release: This control method relies on flooding the area of an infestation of wild flies with sterile flies produced in rearing facilities. When the sterile flies mate with the fertile population, no offspring are produced. Gradually, the wild flies can only find sterile flies to mate, the wild population is eradicated.

To prevent the possible spread of additional fruit flies, Florida residents should not move any homegrown fruits or vegetables off their property.

USDA-ARS scientists in Hawaii and Texas collaborated in investigating phloxine B, better known as the FDA-approved red dye number 28. The dye proved to be as effective as malathion-bait sprays and might be a safe, effective alternative to previously used aerially-applied malathion insecticide baits. Medflies often share regurgitated food. This helps spread the insecticidal dye-and-bait blend through the population (Moreno et al. 2001).
