USA Flag Ceratitis capitata (Medfly) Detections and Quarantines in San Bernardino County and Santa Clara County, California
Date posted: 10/25/2005
Contact: Not available

SAN BERNARDINO COUNTY, CALIFORNIA

On October 7th and 9th, two more wild adult Medflies were detected in a separate core square mile approximately 2.5 miles northeast of the original detections in Rancho Cucamonga, CA (see PAS Official Pest Report for 10/05/2005).  Also on October 18, a mated wild female medfly, was trapped in a IPMT trap in a grapefruit tree. This detection is 2.3 miles southeast of the original group of finds.

A Federal and State quarantine was established of approximately 81 square miles surrounding the first group of detections. The Federal quarantine was established by Federal Order on October 4th. With the new detections establishing a new core, California Department of Food and Agriculture and APHIS will expand the quarantine boundaries. Foliar treatment, using protein bait spray (Spinosad), will be applied to all host trees within 200 meters of detection sites.

SANTA CLARA COUNTY, CALIFORNIA

October 5th and 9th 2005 two wild Medflies were captured approximately 1 mile apart in a residential area of southern San Jose, CA. An increased delimitation survey is being conducted surrounding the two detection sites.

Foliar treatment will be applied to all host trees within 200 meters of the detection surrounding the detections in San Jose. The rate of aerial sterile fly release will be increased to 250,000 sterile male Medflies per square mile per week in a 10 sq mile area surrounding the infested property.

A Federal Order has been posted delineating the new quarantine area in Santa Clara County.
