Mosquito Control for Professionals
In the continental United States, professionals from local government departments or mosquito control districts use integrated mosquito management (IMM) strategies to control mosquitoes that spread viruses like West Nile, dengue, or others. Outbreaks of West Nile virus happen every year. Sometimes a virus like dengue is introduced by an infected traveler to areas of the United States with Aedes aegypti mosquitoes.
- Before cases of West Nile virus are reported or before locally acquired cases of dengue, chikungunya, or Zika virus infection occur, professionals conduct surveillance to understand local populations of mosquitoes and begin control efforts.
- If a travel-related case of infection is reported or a locally acquired case is suspected, mosquito control professionals enhance mosquito control activities to reduce both larvae and adult mosquito densities. This can help keep mosquitoes from biting infected people, which can break the transmission cycle.
- Mosquito surveillance and control efforts should target the mosquito species that can transmit viruses.
- To delay or prevent the development of insecticide resistance in mosquito populations, integrated mosquito management programs should include a resistance management component.
CDC created and maintains a national surveillance system called MosquitoNET. MosquitoNET is an online, centralized database to track, report, and store information regarding mosquito collections and insecticide resistance detected through testing with the CDC bottle bioassay.
Participants set up and manage individual accounts in the database to view, add, and edit data on mosquito surveillance and insecticide resistance.
Data from MosquitoNET can be used to:
- Improve knowledge of the biology of mosquitoes across the United States and US territories
- Develop modeling and mapping of mosquito populations
- Understand insecticide susceptibility or resistance patterns
- Prepare for emergency response to mosquito-borne disease
Since its creation in 2016, the focus of MosquitoNET expanded from tracking mosquito vectors of Zika virus to include all mosquito vectors of arboviruses. The goal is to expand the user group so the system can be widely used for reporting all mosquito species data for the US and its territories.
CDC developed the MosquitoNET website to facilitate data reporting for ELC recipients. ELC recipients will use MosquitoNET to report data about mosquito collection and insecticide resistance testing. Data about virus infection in mosquito pools will continue to be collected using ArboNET.
