The susceptibility of
Anopheles aquasalis
(F
3 generation) and
An. darlingi (F
1 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.
