Article Synopsis
- - Insecticides are crucial for fighting vector-borne diseases like malaria and dengue, but increasing resistance to these chemicals jeopardizes their effectiveness in controlling disease transmission.
- - A global study involving 87 countries revealed that pyrethroids are the most commonly used insecticides, especially for malaria control, but resistance management strategies are lacking, particularly for diseases like dengue and leishmaniasis.
- - To tackle insecticide resistance, vector control programs need better coordination in management and monitoring, and should also explore alternative control methods to minimize reliance on a few insecticide classes.
Background: Vector control plays a critical role in the prevention, control and elimination of vector-borne diseases, and interventions of vector control continue to depend largely on the action of chemical insecticides. A global survey was conducted on the management practices of vector control insecticides at country level to identify gaps to inform future strategies on pesticide management, seeking to improve efficacy of interventions and reduce the side-effects of chemicals used on health and the environment.
Methods: A survey by questionnaire on the management practices of vector control insecticides was disseminated among all WHO Member States.
Pesticide lifecycle management encompasses a range of elements from legislation, regulation, manufacturing, application, risk reduction, monitoring, and enforcement to disposal of pesticide waste. A survey was conducted in 2017-2018 to describe the contemporary global status of pesticide lifecycle management, to identify where the gaps are found. A three-tiered questionnaire was distributed to government entities in 194 countries.
