What does resistance management in vector control aim to achieve?

Resistance management in vector control primarily aims to delay or mitigate the development of resistance among vector populations to insecticides. Over time, repeated use of the same insecticide can lead to the survival of those vectors that possess genetic traits allowing them to withstand the chemicals. This can result in a population that is increasingly resistant to the treatment, rendering it less effective.

By implementing resistance management strategies, such as rotating insecticides with different modes of action, utilizing integrated pest management practices, and monitoring insect populations, vector control efforts can prolong the effectiveness of current insecticides. This approach is crucial because maintaining the efficacy of control measures is essential for managing vector populations and preventing the resurgence of vector-borne diseases.

While increasing the effectiveness of insecticides, limiting the spread of vector-borne diseases, and ensuring complete elimination of vector species are important goals in vector control, they are not the primary focus of resistance management. The core objective is to sustain the effectiveness of control methods by addressing the evolutionary responses of vectors to insecticides.
