DALLAS, TX - Another round of aerial spraying of insecticide is under way across the Dallas area tonight to curb the mosquito population.
Rain cut short the first aerial targeting of mosquitoes in more than 45 years Thursday, grounding two planes around midnight.
Dallas County has been the epicenter of the nation's worst outbreak of West Nile virus, which is carried by mosquitos. The virus has killed 10 people and sickened at least 200 others.
Health officials have also set traps to determine the spraying's effectiveness, and another aerial mission is scheduled for Monday night to catch mosquitoes hatched over the weekend.
