Mediterranean Fruit Fly (Medfly) Riverside County Five Medflies were trapped on November 3, 1998, in the Lake Elsinore area. Larvae were found at a new location in Lake Elsinore. All of the finds are within the Lake Elsinore Medfly eradication area. Lake Elsinore Five (5) Medflies were trapped at four sites. In addition, Medfly larvae were found at one new site. All of the finds were near the sites that Medflies were previously trapped (PD78-98;PD80-98;PD81-98).
Haygood Way - November 3 - 1 mated female found in a McPhail trap placed in a tangelo.
Amorose Street - November 3 - 1 male found in a CHAMP trap placed in an persimmon.
Since October 22, 1998, sixty-seven (67) Medflies have been trapped at 25 separate sites (corrected) in the Lake Elsinore area. Larvae have been found on four properties. CDFA initiated ground treatment with malathion bait spray to find properties and adjacents. Ground treatment of all properties within 200 meters of the finds began on October 31. Soil drench treatments with diazinon are planned for the larval properties. The trap densities in the core square miles around the finds is 100 CHAMP/yellow panel traps and 25 McPhail traps per square mile. The trap density in the first buffer of eight square miles is 50 CHAMP/yellow panel traps per square mile, with a 25-20-10 array of CHAMP/yellow panel traps outside the first buffer. Sterile Medfly releases (SIT) is scheduled to begin November
6, 1998. CDFA Insect Biosystematist Kevin Hoffman made the determinations.
