The Buzz is a weekly summary
disseminate important information about mosquitoes and mosquito
control in the City of Portsmouth.
|
Crabbe Aviation LLC treated 250 acres on Craney Island
and 60 acres for the City on Sunday July 27, 2008. |
| Mosquito Activity (Scale from 0 to 5) |
- City wide activity remains a 2 this week due to the presence of
West Nile Virus detected in mosquito samples.
- Traps counts were lower in Churchland this week, and about the
same for the rest of the city.
- We averaged 2.1 inches of rain last week with the storms that
moved through.
- Tiger mosquito counts continue to increase in some areas.
|
| Surveillance and Control |
- Control efforts started early this week with Crabbe Aviation LLC
treating 250 acres on Craney Island and 60 acres of marshy mosquito
breeding habitat for the City. The application was made with a small
yellow plane specially outfitted to spread a dry granular larvicide.
- 1 CDC trap was set this week. The CDC trap was placed at the
landfill and caught 232 mosquitoes, only 37 were salt marsh
mosquitoes. The landfill trap was less than 1/2 the count last week.
The salt marsh mosquito count dropped way down from 400 last week to
37 this week.
- 5 OFP traps were set this week, 236 tiger mosquitoes were
caught. The average number of tiger mosquitoes per trap was 47. The
tiger mosquito counts are predicted to increase especially in areas
where citizens fail to dump out water on their properties to prevent
tiger mosquitoes.
- We received several mosquito complaint calls the first part of
this week. One of the calls was to report a ditch that needed
maintenance, all the rest were related to tiger mosquitoes.
- The crew is actively treating catch basins again this week. With
good weather they should finish the entire city before the week.
- Information on spray activities is posted on the Mosquito Spray
Hotline (393-8666 press 1 when prompted). Citizens can call and
listen to a recorded message to find out what areas are scheduled
for mosquito spraying.

| Federal Activities |
- The Army Corps of Engineers had their contractor treat 250 acres
on Craney Island Sunday. The goal was to treat standing water from
the heavy rain late last week. Everything points to a successful
application. The aerial application of larvicide is only one part of
the successful program; source reduction efforts and contract ground
based larval control efforts are paying dividends.
