TALLAHASSEE, Fla. (AP) - A peach fruit fly was found in a trap in a guava tree in Miami-Dade County.

A U.S. Department of Agriculture inspector found the fly earlier this month. It's the first of its species to be found in Florida.

Florida Agriculture and Consumer Services Commissioner Charles H. Bronson says exotic fruit fly infestations pose a serious threat to Florida's crops.

Peach fruit flies attack many different types of produce. They lay their eggs, and maggots render the fruits or vegetables inedible after a few days.

In June, Mediterranean fruit flies were trapped in Palm Beach County, and a full-scale, three-month eradication program was conducted. In August, two Oriental fruit flies were found in a trap in Pinellas County, but no additional flies have been found.
