09-01-2010 Proposed Boundary
 

 
08/30/2010
On 8/28/2010 two additional Melon Fruit Flies were trapped approximately 1.5 miles south of the original finds. The quarantine boundary will extend farther south and the quarantine time frame has just started over. We are generating new maps, and as new information becomes available I will keep you updated.
 
Just a reminder about the quarantine treatments as there has been some confusion about the rates and timing for treatments prior to harvest. Any of the Malathion 8 formulations, as per CDFA Pesticide Rate Chart within the Quarantine Zone, is listed at 1.5 ounces per acre. Work with the "Project Area" (661-861-4131) for applications and compliance agreements.

Outside the Quarantine Zone, the label rate of 1.5 ounces per acre has been approved as well, but in order for your treatment to comply with the treatment schedule it must be witnessed by my county office. Please call 661-868-6300 if you are going to spray your crop outside the Quarantine Zone. The minimum period of treatment is 30 days, but can be extended beyond that determined by the average, local seasonal temperatures, with treatments occurring at 6-10 day intervals. Project Regulatory officers will monitor all treatments.

PLEASE review the Harvest to Bait Treatment Schedule. After October 22nd the harvest interval changes from 30 days to 111 days. If you have any questions please call 661-868-6300.

Fruit removal is complete. About 5,400 pounds of fruit from the two residential find site properties and from the few trees with fruit at the adjacent dying peach grove have been removed. Peppers will be cut and removed on Monday using the CCC. Eradication trapping is about 90% complete and should finish tomorrow. Detailed fruit removal, eradication, and spinosad treatment reports will be sent on Monday.

The core and first buffer traps will be serviced and deployment of the last 25 grids in the outer buffers will continue.
 

 
08/11/2010
On August 10th, 5 Melon Fruit Flies (MFF) were detected in a single trap south of Meridian in Kern County (South Eastern Portion of the County). CDFA Entomologist Dr. Hoffman has confirmed them to be wild. Two male and three female MFF (Bactrocera cucurbitae, rated "A"). On August 11th, one more additional MFF was trapped in close proximity to the first trap. This has triggered eradication and quarantine protocols. Attached is the Quarantine Request, CDFA Action Plan, Host List and Kern County Melon Fruit Fly News Release.
 
UPDATE: Delimitation trapping began in the 81 square miles around the find site. Placement in the core and first buffer is complete. In the second, third, and fourth buffers 25 grids still need to be placed. A total of 415 melon fly baited Jackson traps and 9 McPhail traps were placed.
