Vector control and insecticide resistance

Sarah Hoibak/UNHCR

Vector control is a fundamental element of the existing global strategy to fight malaria. Vector control interventions have a proven track record of successfully reducing or interrupting disease transmission, particularly in areas that are highly prone to malaria. Indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs) are the two core, broadly applicable malaria vector control measures. This section covers both core and complementary vector control methods and discusses the action that is required to prevent and manage the increasing challenge of malaria vector resistance to insecticides.

Core vector control methods

Indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs) are the two most important vector control measures that protect humans from the bite of malaria-carrying mosquitoes.

Complementary vector control methods

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

Insecticide resistance

Endemic countries are urged to draw up and implement comprehensive insecticide resistance management strategies and ensure timely entomological and resistance monitoring.

WHO-approved 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 long-lasting insecticidal nets (LLINs) and insecticide compounds and formulations for IRS and other vector control interventions where appropriate.

Policy setting for vector control

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