Olive Fruit Fly (OLFF) Los Angeles County Westwood Olive fruit fly larvae were found on one property. Also a female OLFF was trapped near recent finds (PD76-98;PD88-98). While inspecting olives on November 12th at a recent OLFF find site, CDFA Alicia Ruiz and Maria Ramirez found larvae. In addition, an unmated female OLFF was trapped on November 12 at a residence along Holman Avenue. CDFA trapper Ruben Perez found the fly in a McPhail trap that was placed in an olive tree. The trap density at the time of the find was 80 McPhail traps per square mile. Olive fruit fly does not respond to cuelure or methyl eugenol. CDFA will increase the McPhail trap density, as needed, to 80 traps per square mile in the core square mile and 40 McPhail traps per square mile in the eight adjacent square miles. In addition, CDFA is conducting a larval survey on find properties and their adjacents. Since October 19, 1998, eleven olive fruit flies have been
trapped in Westwood. Larvae have been found on one property.
CDFA has scheduled ground treatment with malathion bait spray
all olives within 200 meters of OLFF finds to begin on November
16. Soil drench treatments with diazinon will be made to the
one larval property and its adjacents.
