The susceptibility of Anopheles aquasalis
generation) and An. darlingi
generation) to Plasmodium vivax
circumsporozoite protein phenotypes from a limited number of blood samples of malaria patients in Belém, state of Pará, Brazil, was examined. A polymerase chain reaction was used to determine the P. vivax
phenotypes in blood samples and the blood-fed infected mosquitoes were dissected and tested by ELISA. In all patient infections, more infected An. aquasalis and An. darlingi
were positive for VK210 compared with VK247.
