Olive Fruit Fly (OLFF) Los Angeles County Two female OLFF were trapped on February 22, 1999, in Los Angeles County. One of them was in Westwood and is within the Los Angeles/Westwood OLFF treatment area. The other find is in Los Angeles and is outside the treatment area. In addition, OLFF larvae were found between February 24 and March 1 at three new sites in Crenshaw. These finds are near previous adult finds in Crenshaw and are outside the treatment area. Crenshaw

Westwood
CDFA trappers German Jara, Corine Lopez, Jerry Morales, Maria Ramirez, William Rodriguez, Ernesto Ronquillo, Alicia Ruiz, and Lupe Segura are credited with finding the OLFF. CDFA Insect Biosystematist Ray Gill and Kevin Hoffman made the determinations. Olive fruit fly does not respond to cuelure or methyl eugenol. CDFA has increased 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, AM panel/CHAMP traps have been deployed at the same density as the McPhail traps within the delimitation trapping area. CDFA is continuing a larval survey on find properties and their adjacents. Since October 19, 1998, a total of 299 olive fruit flies have
been trapped in California. Two hundred and eighty-four (284)
OLFF have been trapped in the Westwood area of Los Angeles and
larvae have been found on 14 properties. In response, CDFA
has initiated ground malathion bait to all olive trees within
200 meters of these finds. Also, thirteen (13) OLFF have been
trapped at separate sites in Alta Dena, Bel Air Estates, Crenshaw
(3), Hawthorne, Inglewood, Los Angeles(3), Manhattan Beach, Redondo
Beach and West Hollywood areas. CDFA has increased trapping
according to protocol around these finds.
