Mediterranean Fruit Fly (Medfly) Two Mediterranean fruit flies were trapped on October 27 and 29, 1998, in Orange and Riverside Counties. Orange County Mission Viejo One unmated female Medfly was found on October 27th in a McPhail trap placed in a fig tree along Alturas Drive. The site is within the Lake Forest sterile Medfly release zone. Since the find is within the core of the delimitation trapping area, CDFA will not deploy any additional traps. However, these core traps will be serviced daily for a week. CDFA trapper Karen Gailey and I.D. sorter Julie Little are credited with finding the Medfly. Riverside County Sedeco Hills Since October 22, 1998, five Medflies have been trapped at separate sites in the Lake Elsinore area. CDFA initiated ground treatment with malathion bait spray to find properties and adjacents. Ground treatment of all properties within 200 meters of the finds will begin October 31st. The trap densities in the core square miles around the finds will be 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 next week. CDFA Insect Biosystematist Kevin Hoffman made the determinations.
