Entomology and vector control


Vector control is an essential component of malaria prevention. Such control has been proven to successfully reduce or interrupt malaria transmission when coverage is sufficiently high. The two core, broadly applicable measures for malaria vector control are long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS). In specific settings and under special circumstances, these core interventions can be supplemented by other methods.

Core vector control methods

Long-lasting insecticidal nets (LLINs) 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.

WHO-recommended products for vector control

The WHO Pesticide Evaluation Scheme (WHOPES) coordinates the testing and evaluation of pesticides for public health, and makes recommendations on vector-control tools such as LLINs, insecticides for IRS, and other vector-control interventions as appropriate.

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 two 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.
