  • The Impact of IRS on Malaria Prevalence and Entomological Indicators in Senegal, Dr. Lassana Konate, Université Cheikh Anta Diop of Dakar

Insecticide-based malaria vector control, indoor residual spraying (IRS), and insecticide treated nets (ITNs) have been scaled up significantly in recent years. The increase in coverage of these proven interventions has been associated with a decline in the malaria burden in a number of malaria endemic countries and territories including in sub-Saharan Africa. At the same time, insecticide resistance in local vector populations has been detected, which presents a severe and rapidly growing threat to malaria control gains. To slow down and mitigate the inevitable evolution of resistance, inclusion of strong, comprehensive entomological monitoring within vector control programming is vital. Indeed, strong entomological monitoring in IRS-targeted areas is critical to the success of IRS programs. Yet, in many resource poor settings, availability of such data and its influence on programmatic and policy decisions may be limited. Drawing on country examples, this symposium explores innovative approaches to gathering necessary entomological and epidemiological data and reveals how certain country programs have used this information to shape their IRS programs. We will hear examples of how local capacity can be built in countries with limited resources or conflict (e.g., Angola, Mali) for maximum entomological monitoring. We will learn how good entomological monitoring and evaluation played critical role in proper IRS targeting in Zambia and brought about significant cost savings as well. We also will learn how annually-collected insecticide resistance data from the President’s Malaria Initiative-supported IRS areas are informing decisions regarding insecticide selection. From Benin, we will see the epidemiological implications of such decisions. From Mali, we will gain an understanding of the importance of national resistance mapping for malaria control.


Symposium: Indoor Residual Spraying: Maximizing Innovation, Impact, and Sustainability

Tuesday, October 8, 2013, 13:30-15:00

Meeting Room 21

Chair: Bradford Lucas, Abt Associates
Chair: Allison Belemvire, United States Agency for International Development, President’s Malaria Initiative
Chair: Kristen George, United States Agency for International Development, President’s Malaria Initiative


  • Maximizing Entomological Monitoring in Low Resource Settings: Building Local Capacity, Dereje Dengela, Abt Associate
  • Smartphones for Enhanced Environmental Compliance in IRS, Peter Chandonait, Abt Associates
  • Using Insecticide Quantification Kits to Maximize the Efficiency and Impact of IRS, Christopher Helm, IVCC
  • Increasing Sustainability and Cost-effectiveness through Community-owned IRS: Results from Ethiopia’s Pilot Program, Dr. Yemane Ye-ebiyo Yihdego, Abt Associates

IRS is a key component of malaria prevention programs in many countries. IRS is proven to reduce the density and longevity of malaria transmitting mosquitos and correspondingly reduce malaria prevalence in target populations. The planning and implementation of IRS campaigns is complex – requiring expertise in operations logistics, entomological monitoring, environmental compliance, and monitoring and evaluation (M&E). This symposium highlights four innovations in IRS that are contributing to increasing the impact and sustainability of country programs. In Ethiopia, a successful piloting of a community-based IRS approach is now being replicated in other districts as a more cost-efficient and sustainable model. New technology to measure the amount of insecticide sprayed on wall surfaces has the potential to dramatically improve spray quality assurance and residual life monitoring. The application of smartphones to IRS campaigns is making it easier for program managers to monitor critical environmental compliance activities. Enhanced entomological monitoring is demonstrating the impact of IRS programs on key entomological indicators and malaria prevalence. Scaling up of these innovations at the country level can increase the impact, reduce the cost, and make IRS more sustainable.
