Optimizing Strategic Insecticide Resistance Management Planning in Malaria Vectors

Abstract

In the past decade, there has been rapid scale-up of insecticide-based malaria vector control in the context of integrated vector management (IVM). But, the continued efficacy of vector control interventions is threatened by the selection of insecticide resistance. Evidence of insecticide resistance operationally undermining malaria vector control programmes is invariably mounting and is resulting in policy changes. Monitoring and management of resistant disease vectors is essential to limit the selection and spread of insecticide resistance and to maintain the effectiveness of vector control. Thus, countries are encouraged to implement pre-emptive insecticide resistance management (IRM) strategies against malaria vectors according to the Global Plan for IRM. However, substantial challenges for implementation exist at country level. The IVM strategy provides a potential platform that could be exploited for enhanced national strategic IRM planning and operationalisation. Nevertheless, significant coordinated response among stakeholders and political commitment is needed for timely and effective policy implementation within the context of a national health system.

Current status of insecticide resistance in malaria vectors in the Asian countries: a systematic review

“…The efficacy of mixed nets, is because it prevents mosquito bites (function of resistance and physical integrity), and kills mosquitoes (function of chemical content and mosquito susceptibility) 35 . Resistance has been observed in more than 500 insect species worldwide, among which over 50 Anopheles species (Diptera: Culicidae) are responsible for the transmission of malaria parasites to humans 36 . Since monitoring of the resistance was a critical element for implementing insecticide-based vector control interventions, there was a need for periodic surveillance at least once a year or preferably every six months 13 .…”
