Only pyrethroids can be used to treat bednets and, although four insecticide classes are approved by the World Health Organisation for use in IRS, the vast majority of programmes spray with pyrethroids. An inevitable consequence of the scale up of malaria control has been the emergence of insecticide resistance in the <em>Anopheles<\/em> vectors. Pyrethroid resistance was first detected in <em>Anopheles gambiae<\/em> in West Africa in 1993 and remained relatively rare until the end of the twentieth century. But in the past 10 years reports of pyrethroid resistance in the major African malaria vectors have escalated (Figure 1) (Ranson <em>et al<\/em>, 2011).<\/p>\n<p>Action must be taken to ensure that this resistance does not compromise malaria control. The AvecNet project (www.avecnet.eu) was established in 2011, with funding from the European Union Framework 7 programme, with the goal of developing new or improved mosquito control tools to complement existing interventions and control insecticide resistant populations. Some of the key activities and outputs from this project are described.<\/p>\n<p><strong>This is an preview of a full article published in Outlooks on Pest Management \u2013 February 2014 issue.<br \/>\n<\/strong><\/p>\n<p><a href=\"http:\/\/www.ingentaconnect.com\/content\/resinf\/opm\/2014\/00000025\/00000001\/art00010\" target=\"_blank\">The full text of this article is available to subscribers of Outlooks on Pest Management.<\/a><br \/>\n<a href=\"http:\/\/www.ingentaconnect.com\/content\/resinf\/opm\/2014\/00000025\/00000001\/art00010\" target=\"_blank\">Non-subcribers may buy &amp; download fulltext article.<\/a><\/p>\n<p><strong>Author:<\/strong> Hilary Ranson,\u00a0Head of Department of Vector Biology, Liverpool School of Tropical Medicine, Pembroke Place, Liverpool, L3 5QA, UK<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Prevention of malaria is best achieved by controlling the mosquito vector which, today in Africa relies almost entirely on the use of residual insecticides inside the home.
