Sebring

Fly count: No more flies were found yesterday, leaving the total at 115 since the initial find on July 9. Traps are still coming in today, but so far, no more flies have been detected.

Traps: There are currently 2972 traps deployed: 2247 Jackson, 176 McPhail, and 549 yellow panel traps. An additional 50 traps were placed yesterday within a 4 square mile radius of the new find.

Treatment: Ground treatments were made in a half square mile radius around the new fly find in commercial groves. In addition, ground treatments were continued in the buffered areas around exclusion sites in the northern block.

Environmental Monitoring: The following results are from water samples collected by FDACS staff prior to and following the first aerial bait treatment.

July 17 - pre-treatment results
Dinner Lake BDL (Below detectable level)
Little Red Water BDL
Lake Sebring BDL
Lake Denton BDL
Little Bonnet BDL

July 18 - post treatment results
Dinner Lake BDL
Little Red Water 0.6 ppb
Lake Sebring 1.4 ppb
Lake Denton 0.1 - 0.3 ppb (between the MDL and PQL)
Little Bonnet 0.1 - 0.3 ppb (between the MDL and PQL)

The minimum detection level (MDL) is 0.1 ppb and the practical limit of quantification (PQL) is 0.3 ppb.

All samples were BDL for malaoxon. The MDL for malaoxon is 0.1 ppb. NOTE: These results are comparable to results in Umatilla, where aerial bait treatments were also made using helicopters and 100 meter buffers.

Health Monitoring: No report.
