Locations of entomological surveys conducted previously and for the present study [74]. Human malaria sporozoites were discovered from dissected mosquitoes from these sites between 1951–1999 [24,25,26,27, 29] (triangles). Plasmodium knowlesi and other simian malaria sporozoites were discovered from dissected mosquitoes and by nested PCR assays from this site between 2005–2006 [30] (circle). The study site for the present study is indicated by a square
