Insecticide Resistance a Growing Threat

Heat map of reports of insecticide resistance in Anopheles mosquito species in Africa.

Progress in malaria control in the past decade can be attributed largely to the massive scale-up of insecticide-based interventions targetting malaria-carrying mosquitoes. Insecticidal bed nets and indoor sprays saved over 700,000 lives in 34 countries between 2001 and 2010.

The emerging and rapid spread of insecticide resistance threatens the utility of these tools. The effectiveness of these tools must be maintained if global progress against malaria is to be sustained and increased.

Up-to-date information on insecticide resistance must be used to guide the deployment of insecticidal tools to ensure the right tool is used in the right place at the right time. Malaria control policy makers and researchers have been calling for a user-friendly approach to visualizing and exploring up-to-date information on insecticide resistance.

With increased attention to monitoring the spread of insecticide resistance, the volume and hence complexity of the data set is expected to increase rapidly. To make the most of available information, an interactive map of all publically-available insecticide resistance data has been developed.

 

What is IR Mapper?

IR Mapper is a tool used to view results from insecticide studies (WHO susceptibility tests) using malaria mosquitoes collected from sites throughout the world.It can also be used to view results from investigations of insecticide resistance mechanisms (molecular and biochemical assays) in malaria mosquitoes collected from the same or different sites.

Users are also able to view their new data from insecticide susceptibility and resistance mechanisms tests alongside existing published data. For all reports, insecticide susceptibility status is based on the updated WHO criteria (<90% mortality = confirmed resistance).
