Olive Fruit Fly (OLFF) Los Angeles County Los Angeles County CDFA trapper Enrique Enciso found two OLFF at two new sites.
On March 26, 1999, one sexually mature male was found in a CHAMP
trap place in an olive tree along Venice Boulevard. On March
29, 1999, one sexually immature, unmated female was CDFA Insect Biosystematist Eric Fisher made the determination. 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 309 olive fruit flies have
been trapped in California. Two hundred and eighty- eight (288)
OLFF have been trapped in the Westwood area of Los Angeles and
larvae have been found on 15 properties. In response, CDFA
has initiated ground malathion bait to all olive trees within
200 meters of these finds. Also, nineteen (19) OLFF have been
trapped at separate sites in Alta Dena, Athens, Bel Air Estates,
Brentwood, Crenshaw (6), Hawthorne, Inglewood, Los Angeles(3),
Manhattan Beach, Redondo Beach, View Park, and West Hollywood
areas. CDFA has increased trapping according to protocol around
these finds.
