Report Dated 06/27/98

Bradenton

No flies have been detected through 06-26-98. The total count, since the first fly was found on May 17, is 553 flies. The last fly was trapped on 6-14-98.
The third and final aerial bait treatment took place Thursday evening 6/25, following a weather delay the night before. Treatment began around 10:00 pm and was completed around 3:30 am. Ground treatment in the buffer zones was scheduled for completion today.

Sterile release has continued in Hillsborough, Manatee and Sarasota Counties. I believe we will be releasing sterile flies over the treatment zone in the next day or two.

With the conclusion of the aerial bait program, I will be decreasing the frequency of these updates. I'll send one out as I receive the results from the data we've been collecting, or when there is something new to report.

On behalf of my Department and USDA I'd like to thank all of the folks who have been helping us through these outbreaks - DOH/Tallahassee, Lake CHD, Marion CHD, and Manatee CHD, DEP/Orlando, DEP/Tampa, EPA HQ and Region IV, and my own staff who have kept the Bureau of Pesticides on track while my time and attention was diverted here.
