Fig. 4From: Malaria surveillance from both ends: concurrent detection of Plasmodium falciparum in saliva and excreta harvested from Anopheles mosquitoesSpearman’s rank correlation between presence of sporozoites in salivary glands and RT-rtPCR detection of P. falciparum. Each dot represents a group of 5 mosquitoes in a container, sampled from day 15 to 19 post-exposure.
