Contact: Not available
One mated female adult Oriental Fruit Fly (Bactrocera dorsalis) was detected on August 29, 2006 in a Jackson trap baited with Methyl Eugenol in the Rialto area of San Bernardino County, California. The detection trap was in a residential area.

As a result of this mated female detection, a quarantine boundary was established to encompass approximately 65 square miles of San Bernardino County, California. The quarantine area encompasses the treatment area surrounding two previous detections on August 8, 2006, in the Fontana area of San Bernardino County.

There are no commercial host production sites nor are there any packing facilities located within the quarantine area. The closest area of  host production is approximately 15-20 miles away from the quarantine area.

A male annihilation treatment of 600 bait stations of Naled/Methyl Eugenol per square mile is being applied to a 1 ½ mile area surrounding each detection and will be repeated at two week intervals for two life cycles after the last fly captured. Foliar treatment, using protein bait spray (Spinosad), is being applied to all host trees within 200 meters of each detection.
