Olive Fruit Fly (OLFF) Los Angeles County An OLFF was trapped on December 2, 1998, in Manhattan Beach. On December 1, an OLFF pupal case was found on a new property in the West Los Angeles area. Manhattan Beach Los Angeles County Department of Agriculture trapper Robert Wieder found a male OLFF in a McPhail trap placed in a lemon tree along 11th Street. The find is approximately 11 miles south from the OLFF previously trapped in the West Los Angeles/Westwood areas. The McPhail trap density in the area was five traps per square mile. CDFA will deploy additional McPhail and AM panel traps at a density of 80 traps per square mile in the CORE and 40 traps of each in the adjoining square miles. West Los Angeles
CDFA inspectors Antonio Urequieta and Lupe Segura are credited with finding the pupa. 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 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, thirty-two olive fruit flies have
been trapped at eight sites in Westwood and Cheviot Hills areas
of Los Angeles. Larvae/pupa have been found on nine properties.
CDFA began ground treatment on November 16 with malathion bait
to all olive trees within 200 meters of the Westwood area finds.
