Global report on insecticide resistance in malaria vectors: 2010–2016

Insecticide-based vector control is a cornerstone in the fight against malaria. Yet insecticide resistance in malaria vectors threatens to undermine its effectiveness. In 2012, WHO released the Global plan for insecticide resistance management in malaria vectors (GPIRM). Among other priorities, GPIRM highlighted the need for strengthened resistance monitoring and better management of data, including the establishment of a global database.

As of October 2017, the database comprised almost 30 000 records, including results from bioassays to measure phenotypic resistance, and biochemical and molecular tests for resistance mechanisms. The current report presents an overview of data on malaria vector resistance for 2010 to 2016. It aims to provide the baseline for subsequent status updates and to identify any temporal trends. An online mapping tool called Malaria Threats Map allows further interactive exploration of available data.

Insecticide resistance monitoring and management strategies require development and implementation. These should aim to maintain the effectiveness of current malaria vector-control interventions and to integrate proven new tools once available.
