The first discovery this year of a fruit- and vegetable-destroying Oriental fruit fly in San Diego County has been confirmed by the county agriculture department.

The sexually mature male fly was found in an orange tree during routine servicing of an insect trap on May 22 at a Coronado residence, according to Kathleen Thuner, county agricultural commissioner. No eradication program is planned for San Diego, however.

The fly, normally found only in Southeast Asia and the Pacific Islands, deposits its eggs under the skin of fruits and vegetables, including avocados, citrus, bananas, guavas and tomatoes.

In 1984, four of the fruit flies were discovered in the San Diego area, according to Thuner.
