mosquito spraying


This summer, dozens of mosquitos in testing sites across North Texas have turned up positive for West Nile virus. It’s nothing like the record year of 2012 when 89 people died across Texas. So far this year, only two human cases of the virus have been reported in North Texas. But the dry weather that's come after big rains could mean we're in for a long skeeter season.

UT Southwestern has developed a formula that it says could revolutionize the way communities fight West Nile.

And even though recent rains have drenched North Texas, researchers don’t expect a sudden dramatic spike in West Nile cases.

The Dallas Zoo has thousands of new residents.  Two hives of honeybees moved in last week.  The Zoo is partnering with Texas Honeybee Guild to shore up dwindling bee numbers after a big loss last year.

Mosquitoes with West Nile Virus have arrived earlier than ever before in North Texas. Last week, several traps in Richardson had mosquitoes that tested positive for the virus – last year West Nile didn’t appear until May.

The mosquito population in parts of Dallas and Denton counties actually increased after last summer’s aerial pesticide spraying.  But, the Centers for Disease Control found the number of human cases of the mosquito-borne illness went down.

Plans for the 2013 West Nile season are taking shape. Dallas City Council members and County Commissioners get updated this week.

Dallas County plans a new, more aggressive way to control mosquitoes and West Nile virus next year. 2012 was the worst year ever in North Texas: 18 deaths in Dallas County alone. But, beekeepers and organic farmers do not want aerial pesticide spraying as part of the 2013 plan.

The North Texas Poison Control Center says its hotline has received very few calls about health problems following aerial spraying for mosquitoes.

The Centers For Disease Control is now officially calling 2012 the worst year in Texas for the West Nile virus.

Dallas County’s aerial mosquito spraying got a good preliminary report from the Centers for Disease Control, which analyzed more that 250 mosquito traps.

Aerial mosquito spraying is scheduled again tonight for half a dozen cities primarily in southern Dallas County: Duncanville, Ferris, Wilmer, Seagoville, Sunnyvale; plus Rowlett and Mesquite – south of I-30.

Aerial mosquito spraying is over for the city of Dallas, but cities in the southern part of Dallas County are signing up for the air attack on mosquitoes carrying the West Nile virus.

A federal appeals court says Texas can cut off state funding for Planned Parenthood pending a trial over a new law that takes away the money.

Dallas officials say 20 new West Nile virus cases have raised the County total to 262. KERA’s Bill Zeeble reports the second round of the air assault on mosquitoes launched last night at 9 even though leaders initially said that may not be effective.

Aerial spraying for mosquitoes carrying the West Nile virus is “on” for Monday and Tuesday, weather permitting.

Tonight, beginning at 8:30 p.m. Dallas County will continue aerial spraying for mosquitoes carrying the West Nile virus.

Aerial spraying for mosquitoes over Dallas County cities is cancelled for tonight.

At a Saturday afternoon update, County Judge Clay Jenkins said the chance of rain and windy conditions are keeping the planes on the ground until Sunday, Monday and Tuesday nights.

Friday night, storms cut short the spraying effort. Only about 30% of the intended area was sprayed. Planes will hit the remaining 70% Sunday night. Monday and Tuesday spraying will be a second application over the entire targeted area.

Farmers Branch is waiting to find out when planes will spray for mosquitoes. The suburb was not on last night’s schedule. Neither were border cities Addison, Carrollton, Coppell and northwest Dallas.

Fighting West Nile: Resources

Aug 17, 2012

Where did West Nile come from? What are the implications of aerial spraying? Here’s a roundup of information on the virus and how it’s affecting North Texas.

If all goes as planned, aerial spraying is scheduled to begin tonight from 10pm to possibly 2am.

Eleven cities in Dallas County have signed on to an aerial spray attack against mosquitoes. The first West Nile virus air assault could launch tonight at 10:00pm.

Wednesday evening the first of five twin-engine Beechcraft planes arrived at Dallas’ Executive airport. From there they’ll fly 200 to 400 feet above the rooftops of 11 North Texas cities, spraying a fine mist of the insecticide Duet.

Dallas Mayor Mike Rawlings has declared a state of emergency because of escalating West Nile virus cases and deaths.
