Mexican Fruit Fly (MxFF) San Diego County San Ysidro On October 9, 1998, San Diego County trapper Jorge Olivares found one male Mexican fruit fly in a McPhail trap. The trap was placed in a sapote tree along Calle Primera. The trap density in the area was ten McPhail traps per square mile. In response, the McPhail trap density will be increased as needed to 80 traps in the core square mile and 40 traps in the eight square miles surrounding the core. CDFA Insect Biosystematist Kevin Hoffman made the determination.
