Integrating Vector and Nuisance Mosquito Control for Severe Weather Response.

Area of Science:

• Environmental Science
• Public Health
• Entomology

Background:

• Limited resources often force mosquito control programs to prioritize either public health vector control or nuisance species management.
• Post-disaster scenarios, such as hurricanes and flooding, can lead to significant increases in nuisance floodwater mosquito populations, complicating recovery efforts.

Purpose of the Study:

• To highlight the need for integrated mosquito management plans that address both public health threats and nuisance species.
• To discuss the development of guidance for integrated nuisance floodwater mosquito control following severe weather events.

Main Methods:

• Review of mosquito control program limitations and resource allocation.
• Analysis of post-disaster mosquito population dynamics, focusing on floodwater species.
• Development of integrated nuisance floodwater mosquito control strategies.

Main Results:

• Focusing solely on vector control can leave programs ill-equipped to handle emergent nuisance floodwater mosquito populations after disasters.
• Nuisance floodwater mosquitoes, while not always direct disease vectors, can impede disaster response and recovery operations.
• Effective management requires adaptable strategies and resources for both vector and nuisance mosquito control.

Conclusions:

• Mosquito control programs must incorporate comprehensive strategies for both vector-borne disease prevention and nuisance floodwater mosquito management.
• Integrated mosquito management plans are essential for safeguarding public health and facilitating recovery in disaster-affected areas.
• The Texas Department of State Health Services developed specific guidance for integrated nuisance floodwater mosquito control following the 2018 South Texas severe weather events.
