DALLAS — The third round of aerial spraying in Dallas County scheduled for Saturday night has been postponed due to unfavorable weather conditions.

The campaign to eradicate mosquitoes that carry the deadly West Nile virus will tentatively continue on Sunday night at 9 p.m. Aircaft will take to the air again on Monday and Tuesday night for a second round of treatment designed to kill any mosquito larvae that hatched since the initial spraying.

The City of Dallas said the planes were able to spray about 88,000 acres in Dallas County on Friday evening, leaving 222,000 acres yet to be treated.

At least 14 deaths have been associated with West Nile virus in North Texas.

The four aircraft employed in the project were grounded after only a couple of hours Friday night because of bad weather.

The spray planes took off around 8:30 from Dallas Executive Airport for Day Two of the aerial assault, but officials had to call off the spraying around 11 p.m.

Traps are being set in the areas sprayed Thursday night to check on the presence of West Nile in mosquitoes. Results should be known sometime this weekend.

Cities in Dallas County that initially opted out of aerial spraying have a little more time to decide whether they want join the campaign. The deadline is Tuesday at 2 p.m.

Fort Worth will begin a second round of ground spraying on Saturday night. It's the first time in two decades the city has opted to spray for mosquitoes. Workers started out Friday night spraying parts of the 76104 and 76110 zip codes.

Arlington will start ground spraying on Sunday. Health officials will focus on three areas of the city — Jake Langston Park, Arlington Municipal Airport and Doug Russell Park. The spraying will continue through Tuesday.

The latest numbers show Tarrant County has 199 reported human cases of West Nile virus; Dallas county is now up to 242. Denton County reports 96 cases of West Nile and and Collin county has 34.
