Malaria

Entomology and vector control

Illustration

Vector control is a vital component of malaria control and elimination strategies as it can be highly effective in preventing infection and reducing disease transmission. The 2 core interventions for malaria vector control are insecticide-treated nets (ITNs) and indoor residual spraying (IRS). In specific settings and under special circumstances, these core interventions can be supplemented by larval source management and personal protection measures.


Core vector control methods

Insecticidal-treated nets (ITNs) and indoor residual spraying (IRS) are the two most important vector-control measures that protect humans from the bites of mosquitoes carrying the malaria parasite.

Supplementary vector control methods

In specific settings and circumstances, the core vector-control interventions can be supplemented by other methods, such as larval source management and the scale-up of personal protection measures.

Entomological surveillance, and intervention monitoring and evaluation

Up-to-date local information is required to inform vector control and identify challenges to its effectiveness, such as insecticide resistance and residual parasite transmission.

Insecticide resistance

Malaria-endemic countries are urged to draw up and implement comprehensive insecticide-resistance management strategies, and to ensure timely resistance monitoring.

Entomology and vector control data collection and collation tools

Electronic tools, based on DHIS2, have been developed to support countries strengthen the collection, reporting and use of malaria entomology and interventions monitoring data to inform the planning and deployment of effective vector control intervention.

Advisory committees on vector control

The WHO Vector Control Advisory Group (VCAG) on new tools and the Technical Expert Group on Malaria Vector Control (VCTEG) are the 2 main advisory bodies addressing operational and policy topics related to malaria vector control.

An integrated approach for the control of vector-borne diseases

The Global vector control response 2017–2030 provides a new strategy to strengthen vector control worldwide through increased capacity, improved surveillance, better coordination and integrated action across sectors and diseases.
