Successful malaria control and eventual eliminafion in the non-Amazonian region of Lafin America requires effective control of Anopheles mosquitoes that serve as malaria vectors. Each country of this ICEMR networic, Colombia, Guatemala, Panama, and Peru, has a National Malaria Control Program (NMCP) that features vector control. However, effecfiveness is limited by insufficient informafion on species of Anopheles mosquitoes that serve as malaria vectors, uncertainties regarding the impact of anthropogenic environmental changes on the dynamics of malaria parasite transmission, limited effective tools for vector control, and incompletely developed integrated vector management (IVM) components of NMCPs. The goal of this project is to address major gaps in our understanding of the ecology, behavior, vector potenfial, and control of Anopheles malaria vectors to guide the development and implementation of more effective IVM strategies of NMCPs. Based on extensive preliminary data and experience of team members representing academic institufions and NMCPs in each country within this ICEMR network, priorifies for research focus on key scientific questions that have a direct bearing on the future success of vector control operafions. This project includes 3 specific aims: 1) invesfigate the ecology, behavior, and malaria parasite transmission potential of malaria vector species to identify key factors that would facilitate more effective targeted vector control, 2) determine how known and suspected malaria vector species from each country in the ICEMR network differ in their innate vector competence for Plasmodium falciparum and P. vivax, and 3) assess the efficacy of current vector control operafions of NMCPs and conduct mulfi-country field trials of new vector control products that may strengthen capacifies of NMCPs to implement effective IVM strategies for vector control, In partnership with NMCPs, the ICEMR team will demonstrate the translafional value of research outcomes for improving vector control in ecologically diverse areas o f t he non-Amazonian region through an iterafive process of strengthening and evaluating IVM components of NMCPs.
