Mexican Fruit Fly (MxFF)

San Diego County

San Diego

On November 24, 1998, one sexually immature male Mexican fruit fly was trapped at a site along 55th Street. The MxFF was found in a McPhail trap that was placed in a grapefruit tree and the site is within the the San Diego Mexican Fruit Fly eradication zone.

CDFA has two Mexican Fruit Fly eradication projects in the El Cajon and San Diego areas of San Diego County. Sterile Mexican fruit flies are being release in a total area of 33 square miles (El Cajon - 10 square miles /
San Diego - 23 square miles).

The McPhail trap density in the area is five traps per square mile which is the protocol for SIT release areas.

CDFA trapper Gloria Vargas and USDA I.D. sorter Jody Jordan are credited with finding the Mexican fruit fly.

CDFA Insect Biosystematist Kevin Hoffman made the determination.
