Report Dated 06/01/98

Bradenton

The fly count is up to 537, as of Sunday, May 31st.  While most of the flies have been found in the core areas, we continue to trap single flies outside the core.  Yesterday, an additional fly was trapped in Palmetto, about a mile northeast of the earlier finds.   In response to this find, program directors are proposing an extension of the regulated area, west of  I-75, and north of the Manatee River.

The early report for this evening indicates no flies for today, however, that is preliminary - traps were still being read.

Ground applications continue, as part of the third sweep of the area.

Preliminary results from the DNA analysis of the flies in Manatee County are consistent with the flies found in Tampa last year.  As before, additional, more refined analyses will take a little longer to complete.

USDA submitted a request to USEPA today, for aerial application in this area.

USDA met with the Palmetto City Council, at their request, to provide city officials with an update of the situation.  The Council was informed that attempts to contain the infestation using only ground treatment does not  appear to be successful at this point in time.  Consequently, USDA has requested approval for aerial bait treatment over an area which is now covers roughly 50 square miles, and which includes the city of  Palmetto.  It was noted that the size of the treatment area is still being defined, and may either increase or decrease depending on the fly counts and distribution of the finds over the next several days.  The aerial bait treatment being proposed will include 2 - 4 treatments (one life cycle), followed by release of sterile Medflies.  As previously stated, there will be a public meeting prior to any aerial application.

Council members were also informed of the sterile flies now being released over Manatee County.  Approximately 15 million sterile flies were released  on Sunday, outside the areas where flies have been found.  The targetted density is about 500,000 sterile flies per square mile, and will cover about 140 square miles.  Additional releases will continue,  to reach a total of about 70 million sterile Medflies per week in the Manatee County area.

Umatilla

No more flies have been detected in Umatilla.   There are now 3,999 traps deployed:  3203 Jacksons, 540 yellow panels, 206 McPhails, and 50 IPTs.
