摘要:This research estimates the annual economic impact of the fire ant on key urban sectors in Texas. A study was conducted in 1998-1999 in the 5 metroplexes of Austin, Dallas, Fort Worth, San Antonio and Houston to estimate the costs of controlling and managing fire ants (Lard, et al). This study found that the annual expenditure for fire ant control and management by selected sectors in these metroplexes totaled more than $581 million. The total annual expense by sector amounted to $526 million for households, $29 million for golf courses, $25 million for schools, and $0.6 million for cities. These annual cost figures do not include all urban costs or costs borne by electrical utility companies, communication firms and cable companies. These results can be used to assess damages and estimate the potential costs and benefits of control and management programs, such as the community-based effort underway as part of the Texas Fire Ant Initiative.
